Moving up
Captain Tom Tursi, that was the best well described presentation on docking techniques I have watched. Thank you for this class and for offering it at no charge on youtube.
Really useful video, thanks a million. One comment though, from a Mediterranean sailor . . . . You guys in Maryland seem to think nothing of using the side of your boat in docking, eg when pivoting around a slip post during the 'water man's turn'. At sailing schools on this side of the pond we'd get eaten alive at sailing schools for doing that. Similarly I note you tend only to have a couple of fenders out on the approach side whereas I was always taught to put out every damned one, maybe 6 or 7! Just shows . . . there's more than one way to skin a cat! Thanks again.
Interestingly the technique comes from fishermen on working boats. Perhaps they're less worried about scuffing their paint. ;)
Note also that it was intended for heavy winds. Sees like a good technique for getting control of a boat and turning it in heavy winds. A fenderboard or horizontal fender could be used on the piling to protect the boat better.
Took the class about a month ago (loads of fun and super useful; learned lots of stuff not in this video too). Fenders were only used for flat dock work (i.e. springing in/out). But note that those Island Packets have a nice stainless steel rub rail, which is the only place, that contacted the pilings. And at no time should you be sliding on a piling; at most only rotating around one (else it leaves some wood bits in the rubrail screw heads; how do I know?) But I asked the instructor about boats with pretty gelcoat sides and no rubrail in just the right place to protect them from the pilings. He showed me a flat boat fender (Google it; I'd never seen one before), that was aboard the boat just for that case. Another solution for (against?) pilings is fender boards, which I've seen a couple of times. In New York/New Jersey, where I do much of my sailing, docks are different: Chesapeake has a small tidal range, so often docks are fixed, but in my area it's almost a given that they are floating and typical cylindrical fenders rule. But unlike the Med, stern to docking is rare, so usually only two or three fenders are used per side.
I really enjoyed this presentation, lots of takeaways. For backing a boat into a slip, all of the examples start bow first and then turning to setup the boat to back the stern into the slip. Any thoughts about backing down the fairway stern first and approaching the slip? This is how I normally do it and and its worked well....so far. That said, I'm going to practice some of these techniques.
Backing may be easier overall if it's into the wind or for a starboard approach when going forward and the boat has significant prop walk. It avoids the problem of prop walk working with the wind during a turn from bow forward to stern into the slip. In other words it avoids some of the problems of the starboard approach.
Each boat is very different. I find an isolated buoy or anchor a fender at sea and practice coming up to it foward or reverse at different angles. Great practice with no risks.
Many thanks for a very detailed lesson. I was looking for a instructor to learn how to dock a single inboard fixed with rudder and here it is. I reallly appreciate your time you have put into this lesson. One of the best instruction videos out there to follow and practice. Happy and safe boating.
Very informative and helpful video. Your presentation is planned and executed very well, so that it's logical.
In the case by case scenarios, you address all the key forces that may be involved, except for current. You do mention current forces and describe how they affect the boat in the early portion of the video. In cases where there are also current forces, it's important for sailors to also consider and account for these forces in addition to all the others.
Definitely, though wind is a bit more confounding since it can turn the bow.
One of the best docking technique videos that I've come across. Excellent content. Thank you for creating and sharing this video.
it is a art in docking properly. Take time to present your boat in arriving and departing from your slip or dock side.
Some great tips there thanks. To some off the unanswered questions below I'd recommend really thinking about how the wind at different speeds and directions affects the bow, and where prop walk will take you and try to come up with answers of your own. Any ideas that include higher speed or high power are higher risk... Thinking it out, then time on the water is what makes you proficient. I learn by trial and error trying different suggestions ha ha. Cheers.
I've watched this many times. Just wanted to say thanks for sharing this. You're making the waters safer and helping a lot of people
Hi! Is it possible to download that PowerPoint file? Thx!
Awesome! You sir are an ace instructor. I thought I would never understand propwalk until I watched this video. You are methodical and you know exactly what a novice may be thinking which makes you intuitive. Thank you:)!
Great seminar. Thanks. How do you best SOLO dock a 26' (Pearson 26 OD) sailboat in a river? It has a 9.8 HP outboard. Slip is 2 pilings on each side as shown in seminar. Slip is perpendicular to river. River current is average 3 knots. Current depends on tide shift, so unless I hit it at slack tide, I have current ripping in or out, perpendicular to slip. Wind is usually 10 knots, parallel to river--so when the wind is opposite the current, it's easier to dock, but that is not often the case. It seems like the waterman's spring seems the best option, but once I get the stern in, the bow quickly spins with the current and against the opposite piling. Is there a way to use the waterman's spring and prevent the boat from twisting as I back in? (Going in forwards seems impossible solo.)
Excellent session on docking. Very informative. Looking forward to my upcoming class in March.
I'm curious: why such strong emphasis on backing into a slip at the end? My marina has very consistent westerly winds which blow me toward my slip neighbor. PLUS my prop walk is to the right. Thus, if I were to back in - prop walk would carry me toward my neighbor as the wind carries my bow toward my neighbor. So I go bow in to counter-act. This was a great video... I realize that my smartest choice is to get myself turned around bow to wind. Thus I have to do a standing turn in a narrow fairway. Thank you for sharing this video!
My slip gives me about 8 inches on either side of my 28' sailboat boat, past the fenders, but we only have piling on the starboard side, and an old PT boat on our port, which we don't want to nick and sink. Your video showed me how to use that piling. Thank you!
Excellent video, Thank you for sharing. Paul, Ireland
Excellent. What a comprehensive coverage! Thank you for sharing.
I appreciate the instructions very much. Would love it if you did a presentation on single-handed docking.
Thank You for a great presentation. I liked it so much, just purchased your book through the ASA. Thanks again!
Thanks for your excellent help....For years, every time I entered my slip at Marina Del Ray, I always yelled "Stand by for a RAM" and you would be surprised how fast people appeared ready to help me manhandle my 42 foot Grand-banks on a gusty Day.
Tom,
Great presentation...EXCEPT...the small white cursor arrow is very difficult to see.
Please consider ENLARGING the size of the cursor and CHANING it's COLOR to a higher CONTRAST color like YELLOW.
Much easier to follow.
Raymarine is now using this.
The rookie practicing the cleat hitch around @23:00 mark is starting from the wrong horn :3 Yes, I watched the video about it!
If the rudder is held hard to s/bd during the entire manoeuver; wouldn't the reversing stage be compromised by the rudder in that position?
Would it not be correct to steer port when reversing?
SunriseBoy Boat speed is slow when backing into a slip, so the rudder has little effect on steering the boat. The more important factor, is one of timing. Shifting the rudder to steer in reverse takes time, and the small benefit gained is more than offset by missing the necessary timing for your next action. I usually don't shift the rudder until the fore and aft centerline of the boat crosses the centerline of the slip, since in this case you need to be prepared to throttle kick ahead to avoid a slip piling or dockage that you may be angled toward. Thanks for the question...
Very much and many thanks, Sir, for this great explanation and offering for free out here. I am heading into an app to practice these theories and soon in real life onto the water. Looking forward to it. So, a part of your spirit in here will always be with me when I am docking in for the first time. Wishing u a happy living and fair winds.
Kindest regards,
Efkan
Thank you for a great video - just what i need to “understand” my first boat.
I love this channel. I'm wondering if you have a channel you'd recommend for power boaters. I'm particularly interested in docking techniques for twin engine inboard engine powered boats.
Excellent course from expert instructors. I took this course in person, they are great.
ua-cam.com/video/PoGMAEjiHmU/v-deo.html Be careful with older pedestal controls. I may have misinterpreted the directions for standing turn given in this video and the booklet that goes with it. I went out to practice this on my new-to-me 1980's boat with pedestal steering wheel and controls. With throttle up, I practiced the counting and the pause at each gear. I was just getting the hang of it when the controls broke and I had to get towed in. While searching for parts, I came across a PDF manual for the controls. "When operating engine controls, never shift into or out of gear while throttle is above idle. Forcing the levers or shifting into or out of gear while above idle may result in broken cables, transmission wear or failure and loss of boat control." I'm certain that the controls needed to be replaced due to age, but be aware of this when doing the standing turn. The piece of information I was missing was to throttle down to idle before changing gear.
He does warn you to be careful in the video to ensure you go into neutral, I would assume one would shut the throttle down while changing direction to keep engine rev's down.
Thanks for the seminar. Very helpful! I'm doing a flotilla in a few weeks in the med, so this is a great refresher before this. If you could have the mouse pointer larger, or more highlighted it would be a little easier to follow, but this is only a tiny thing.
Amazing content! I just purchased a 35' trawler with a single screw and I'm so happy I found this! Well done.
Very instructive, detail oriented like not other. Simply the best.
Thanks for an awesome video.
Question regarding: @43:16 (Backing out of slip bow to wind) - What do you do if you are on the right in a double slip i.e. no pilings on the port side AND it's a left handed propeller (stern walks to port) AND there strong crosswind blowing from the fairway exit? I would prefer not to exit fairway stern out
Thank you very much. Much appreciated!
From all those who are not in Maryland (or even in USA) - thanks for a great series of videos!
are there any computer training simulators for docking maneuvers of single engine sailboats (single inboard engine with prop in front of rudder) boats in various wind\current docking conditions? Hmm there may be money in an 80 s style console video game for yacht clubs...
At roughly 1:09:00, what do you do when a neighbor is sharing a piling (you can see in bottom right of pic)? If you put yours on top you run the same problem that you have with a pier bollard. When I was in the Navy, we would slip our line under and through a neighbors line so that we could still pull ours off first. But you can't do that when a line is on a piling and going away 180 degrees like in the pic.
Sir. Thank you for the video, some very good ideas there, well presented.
Could I ask one question? You say that most boats are most wind affected at the bow. If so, using a stern spring and reversing onto it to force the bow out with the wind on the beam or behind the beam night get the bow out, but wind would just blow it back in again when the spring is released. Would it not be more likely to be successful if you motor ahead against a bow spring and get the stern up to wind when being blown onto the dock/pier from the beam or behind the beam? Your three pronged wind arrow could be a little misleading.
Other than than great presentation.
Best Regards
Phil
+philipkenneth24 If you are speaking about parallel undocking, I agree and prefer to use an after leading spring line from the bow and power ahead slowly to push the stern out, and then back out from there... MDS
Actually you're both agreeing. :)
For a "Mediterranean mooring" at roughly 33:00, is there a recommended distance that the anchor is let out? Seems you run the risk of fouling passers-by's props if left out too far? It looks in the schematic to be roughly the length of the boat. Is that to scale?
I have a folding prop. i seem to have problems with kicks in reverse. what do i need to do?
George Lippitt folding props typically are lousy in reverse. My martec prop was great going forward..reverse not so much.
Great instruction. Very methodical. CaptainTursi confirmed a number of things I've been doing and I learned a variety of new techniques and tips. Thank you very much!!
Can some one tell me if I'm wrong about the position of the rudder at the 43:10 mark of this video? In this particular photo it is showing the rudder facing the port side of the boat but if it's a right turning prop wouldn't the rudder want to be towards the starboard side due to the prop walk??? any help is appreciated in advance. thx, RJ
It's the spring line that is steering the boat backing out in this view, not the rudder
Understood... Thank You
@@sailingsvtesla9052 Also, at low speed through the water, prop walk would have more effect than the rudder. But the spring line is doing most of steering the boat at that point.
Great video! Thanks a lot!
Helped me a lot, thank you so much. Do you sell the slideshow?
Very Useful. Thank you Sir!
Excellent instructive. One of my hardest and still not mastered (and I hate it too) is backing in. Thank you!
Choose the tide to park into your slip backwards, into stream and a light breeze from anywhere other than against stream. Blown-on is good. 2 crew. One for the 1st line. One for roving fender and 2nd line.
Stop the boat stern into the stream (out in the river)
Stand forward of the helm facing aft. Never move from this helm position.
Hold it there. Stationary in relation to pontoons. Glance at the bow sometimes but 90% look aft (where you're going).
Practise just with the throttle. Ease and she creeps forward. A tad more revs and she holds. A little more and she creeps backwards into the stream.
Keep holding it in reverse against the stream for a long long time. Until voyeurs get bored and wonder off while you really get the feel of hanging her off the prop, equaling the stream.
Now driving like a car, turn the wheel slightly slightly left. Wait. She will ferry glide left. Then have a go at ferry gliding right... Forget port/starboard.
You're in control.
Reverse Ferry glide into your fairway. At first she'll lose against the stream so Increase revs, just momentarily. Turn more and more into the fairway. Use the +/- throttle to stay central. Get nervous? Turn the wheel back toward the river and ferry glide back out. So, the further in and closer to shore, the weaker the stream. Compensate with helm adjustments. You're 45%-70% now and as your slip opens up will need to turn back towards it with a tad more revs.
You are moving slooowly into your slip, fewer revs as you go. No matter how slow, because you're into stream you will always have water over the rudder and so steerage and you have a clear view of the finger and the pontoon (end of your berth that you will stop 11 inches away from).
Slide her in, slow to a stop and hang off the prop again. Tie off the stern breastline first, hang off it and into neutral. Tie off bow breastline and bow spring. Finished with engine. Stern spring. Kettle on.
Remember the bow spring is the aft one and the stern spring is the forward one. Now reread the lines order again.
Ellul Walker thanks for taking the time to respond. Good advise to stand on until one gets the feeling, i’m always trying to rush a bit. Cheers!
@@Dan_C604 I'm slow as drying paint. Those looking for calamity get fed up and stop gawping.
Also, I think slow. I like time to see what the the boat wants to do and use that rather than fight it.
I like to be going slow enough to have more time and less (wrong) momentum to change if I need to goto plan B. You can always add revs. It's harder to unadd momentum.
My own take is a little different. Swap the contingency and mission.
Plan A. Go up the fairway, turn the boat and leave the fairway. Keep doing that. (survival confidence)
Plan B. When you master plan A, go up the fairway again and if you see a good opportunity to get her in her slip have a go at that. Otherwise complete plan A.
Priority is avoiding collision damage, it is not "to park the boat at all costs".
Or stick with dive in as soon as you're back, barrel up the fairway, take a flier at the turn point, get it wrong. Use even more revs to undo the momentum. Get screamed at because you didn't allow for drift. Wonder what the plan B should have been that you can never visualise anyway. Get teeboned across bow rollers or worse (because you were giving it manly welly to beat whatever "element was king" ).
Excellent and detailed review.
Great Videos. Thank you. I hope you are well.
having a sail drive, some of the ideas don't apply. What about an addendum with information when you don't have access to prop walk? Sail drives are more and more common, and so might be appreciated by many.
Every way works depending on conditions. The only thing you miss out is you need a calculator for all your angles.
Nice and detailed lessons. Thanks.
Standing turn in boat with outboard. Same rule right rudder only applies or is different than with inboard?
Thank you for sharing this great information. Truly appreciated.
Great advise on dock lines. My boat is left hand screw....lol.... Newfie once more.
Thank you very much sir. Picked up my 1st boat, a 40 year old 25 foot single stright shaft right turning power boat APR 2013. Drove it 5 miles from launch point to marina, 5th boat in, tied up alone and haven't left the dock since. Looking forward to a few short trips. Prop walk, so that's what made me look good pulling in. Thank you for posting and doing such a great lesson.
Many thanks, really helpful.
I really enjoyed your video on exiting and entering your slip. Could you please do one using a pontoon boat
very good, very informative to seamanship subject!
Great presentation. - In a parallel undocking wind opposed situation you mention that you prefer stern out vs bow out. Would explain why you believe this to be the case? Thanks..
Rich Jobin I prefer stern out because it's easier to fend off the bow, if necessary, than to fend off the stern. Also, when going bow out, you use your rudder to avoid the boat ahead, and this pushes your stern toward the boat ahead... So in my view, stern out is the better of two evils
Awesome video on docking techniques, liked it very much.
This was an amazing seminar!!
Can you help me figure out how to back out of a slip qith fairway exit to the left with wind on the nose. Thank you!
Thank You.....
Way to hard on drive train. Turn rudder full turn and then punch the throttle.
FYI
This video assumes your boat has an inboard engine. If you have an outboard some of these methods don't work so well.
For an outboard the prop is aft of the rudder so prop wash never really flows over it. For these boats the rudder is only effective when moving through the water, at a stand still such as the "standing turn" the rudder won't do much. If the outboard rotates then use that and let the rudder follow. I've been on a boat with a stationary outboard so all you got is the rudder. Tricky business that boat is.
The point is understand what works on your particular boat.
With an outboard, you can still steer very well in reverse because you essentially have a directional drive unit. You don't need to think about it because you are constantly steering to correct it. Prop walk is only an issue in an inboard situation. If a person has issues docking an outboard or IO because of prop walk, they probably can't park a car either. A person can't understand truly difficult docking until they "stern in" a single screw inboard.
Very instructional, however I thought you short-changed the discussion regarding heading in to a slip. Perhaps that is because you don't use that method as much at your school, but a lot of boaters are relegated to heading in to their slip and must do so in some pretty difficult conditions.
with no wind, what is the best technique to back out a sailboat from a slip when tied up to a finger dock to starboard side and another boat docked parallel on my port side? When backing out, I must turn the stern to the right so the bow heads out of the fairway to open water.
Back out straight. If you have prop walk, turn the rudder slightly in the opposite direction to compensate.
If the fairway is narrow, you can use part of a standing turn to point the bow out to sea. The "back and fill" of a standing turn will turn the boat in a very short distance.
You can also back all the way out of the fairway if you have a place to turn the bow to sea at the end of it.
I was gonna comment and say my boat will do a standing turn at idle, but like you said only right hand turns.. this is a good explanation for me to do a left hand turn, maybe I missed that part but idk... very good explanations.
Thank you, Capt Tom, for a great (and free) detailed seminar! This is a great service to learning boaters like myself. Much appreciated.
Very useful presentation :-) I learned a lot :-)
Thanks
Thank You, I looked like a pro my first time
Comprehensive, indeed. Dealing with all situations of docking!
Going into the slip is much better starting from downwind position and going in one go with slow speed
Just took ASA 118 yesterday. Regarding "Parallel Docking - Hemmed in Dock with Forward Spring "(52:00), our instructor demonstrated this maneuver with a bridle / one long line tied between bow and midship cleat. The bow crew used a boat hook to help place the line over the cleat. A little cumbersome for set up but worked like a charm.
Josh... We published a video on the Docking Bridle last year at ua-cam.com/video/ZJF7nr6TJx4/v-deo.html
@mdschoolofsailing Great! Just watched it. Very helpful. Thank you! We used your slide show as a handout in our class. Thank you for sharing all your knowledge.
I use a doubled line a lot, when I'm getting ready to leave somewhere ill switch my lines over to this, so they can all be released and retreated from the boat ... it works good for me...
Thank you so much for this valuable information. I think I am going to have to watch this video a good few times for all the info to sink in. Thanks once again.
Great job. Very informative and well presented. Thanks.
thank you so much. sametimes i need this video note for print.can you help me sir?
I can't get steerage in my boat unless I'm doing 2 knots minimum in reverse and even then it's iffy if there's wind. I love warps, lol
pretty informative indeed ........................
I’m trying to understand gps and how to read charts and find positions and how to stead the boat and hold the position
Prop walk is a real phenomenon, but the explanation of it here is incorrect.
Prop walk is caused by the interaction of the keel and the prop wash in reverse. The cone of swirling water, which is being driven toward the bow of the boat, deflects off of the keel. It spins counter-clockwise for a right-handed prop, and when it meets the keel, the starboard half of the cone flows up against the hull and then off to starboard. Meanwhile, the port side of the cone deflects down the keel. Because this happens aft of the boat's center of mass, the net effect is to push the stern to port.
As a result, boats without keels and with fin keels have a less pronounced prop walk than boats with full keels.
thedownwardmachine t. Biii
Propwalk is caused by the greater effect of the prop in deeper water. So the down half of the prop causes more effect than the upper half. Propwalk has nothing (!) to do with the keel. The movement of the boat of course is a combination of propwalk and propwash and keel and rudder.
@@tractot12x so energy that is directed in to the object you wish to move has no effect? that is nuts
@@KG-sy2vs That is not nuts, that is completly beside the point.
@thedownwardmachine I think he said "it's kinda like" a rotavator. It was a description of how to easily think about and remember the effect, rather than an explanation of the science.
I don't agree with all of it (because no Mariners agree with everything other mariners say and do) but the point of this seminar is useful takeaway for learners of boat handling.
On the subject of disagreeing. No offence intended but my belief is that your last paragraph is simply 100% the wrong way round.
Can you please do a video on how to use The capstan Of a Windlass for docking or other sailing procedures?
Great lessons, super video, greetings from Quebec
I have the same question as Ed Lecco. Does the school post replies to questions?
xxxboston2 Backing down the fairway is a good maneuver if you can master the techniques of backing in a narrow fairway in a cross wind and possibly a cross current requiring substantial speed for control... Go for it!
Excellent. Thank you!
Thank you for this informative tutorial!
very informative and comprehensive. thx
Very helpful👌🏻 thanks for sharing🙏🏻
great lessons. greetings from Denmark
Excellent and very clear - great info.
Nicely done. Very informative. Thank you!
Is this maneuver able to be performed when you have a tiller and an offset outboard?
very excellent ,learnt a lot of thingsready ,,
Thank you so much
Very Informative.
My new slip doesn't have any useable pilings to warp from (floating dock). Any tips I can try or am I basically limited to just driving it in?
You need to fit big cleats to the corners & other parts of the slip to warp from.
Love this video. Any suggestions coming stern in, starboard tie only with another boat on portside, (no ties, posts to port), and having wind coming off the dock. I could only get this slip in my area, switching is not an option, only going bow in which I don't wish to do. We have a clockwise prop, Hunter 410. I've used the technique at 1:12:40. Trying to find the goldilocks angle position to enter where wrongway stern kick, versus bow falling off is a challenge. In light winds this works well, even though my instincts to centre the rudder early are wrong.
Me too please!
How about the "pivoted sway turn" described here?

Will that do it for you?
