Always nice to see the masonry around the doorway smashed out to remove the boat. The sign of a true boatbuilder.
I grew up building fiberglass sailboats with my dad. For someone who had never done this type of thing before, I was amazed at your craftsmanship. Excellent job. You are an inspiration to others. Thanks!
Mark Grantom agreed!
@@dnick1981 totally agree.
That was an awesome video thank you for sharing it
the stern open to the sea and yet no water gets inside to sink her....that is profound!...the inner tickings of the art of boatbuilding.....thanks for sharing.
+John Rogan I'm sure a shit ton of water gets in but it just flows straight out again. Positive buoyancy bro. That's why he used foam for the core.
seems counter intuitive to let water come on board but I am not a boatwright.
The stern is not really open, it just has a low deck there.
Beautiful boat and thank you so much for step by step descriptions of the process. I have a 13 feet Racelite sailer (made in Vancouver, Canada) , with a 36"x16" - 3/8" steel plate swing keel, having a lot of fun.
Amazingly well presented. The human spirit to create never ceases to amaze me. Well done!
Laughed so hard I thought I would die at the end, you fufilled the old jokeabout building a boat and did not realise you would have to tear the house down to get it out!
There is that. Pick a well ventilated room in which to fibre glass. For bonus points make sure you can get what you are making out of the said room.
Amazing workmanship. Very nicely done. Makes me miss my old Laser 1.
Happy Sailing!
The stringer information I found very useful, thanks for posting. As always with everything, it probably cost as much to build as to buy one. But it sure was fun.
the pipe supports and hardware...pure genius!
Awesome video! Very good photos. I appreciate that you took the time to make this. Very helpful for a guy in the first phase of planning to build a boat. Thank you!
Thanks for the site. Couple suggestions for new fiberglass boat builders based on experience.:
1) Use a good isothalic prepromoted polyester resin instead of epoxy. Just as strong as epoxy and about 10 times cheaper in bulk. With fiberglass, the strenght is all in the glass. The resin makes it stick together and get hard. I know of no commercial boats made with epoxy. Good glass is clear and usually green. Brown means too much hardener.
2) Make fillets in corners with peanut butter (calcium carbonate powder and resin mix) using a ball of the "right" size". Fillets make corners many times stronger. Fair the outer radius with a template if you want. Corners are "stress risers". Fiberglass gets a LOT of it's strenght from flexing and load spreading.
3) Make fiberglass panels using a large sheet of polyethylene (HDPE) on a 2 x 4 frame.. It's the same material milk jugs are made from. Cured resin does not stick, no waxing or release agent needed, First coat can be the gelcoat, then a layer of mat. Panels are easy to work with (just spile them in), less waste, and need little finish work as the surface is completed and mirrors the panel surface. Use hot glue to attach panel sections to form ribs and ribands which are outside the hull. Add glass to the inside to desired thickness.
4) A high density (5 or 6#/cubic foot) polyethylene closed cell foam makes an excellent core for bulkheads, stringers and deck. Not much strenght in the foam, but has compression strenght which supports the glass placed over it. Resin WILL stick to rough closed cell hdpe foam. If foam is used for stringers, bulkheads, and deck...much weight can be eliminated without reducing strenght. Use peanut butter to bed the stringers and bulkheads.
I use polyester almost exclusively, but if I built a boat in my house, I think the low odor of epoxy might be better than the smell of polyester lol.
I see a lot of marine guys swear by expensive foams for foam core, but it seems like if you're not counting on the foam for any strength once the boat is completed, then cheap polystyrene should also work? It just seems like decent glass is so easy to overbuild strengthwise, I can't imagine why you would care about using the foam for anything but making easy structures with glass...
Please, can you share specific product codes? Because I don't know about products quality. I also want to know do you want to add some new products or remove after two years. Thx for your help.
I like the advice, but doesn't polyester, styrene dissolve many foams?
@@murat1968 selam murat, ben yardimci olmaya calisirim sana, tam olarak ne demek istedigini soylermisin?
That was a great video! Thank you so much for taking the time to make it!
Fair winds!
Awesome, the shaping looked perfect. Nice work.
fine work - congratulations. and a very interesting video with a lot of useful info as well. well done, guys!
well done great job boat looks great they are a fantastic boat . from an old javelin sailor in australia
well done mate, looking good, greetings from Greece
She sails great, nice job!
Beautyfull boat... sailing is romantic... is an adventure... is my dream.
thank for this video.
Very good job,and photos,thanks
Brisbane
Awesome job. Thanks for sharing.
Great job especially for a first time boat builder!!!
Great job and great description.
Beautiful job and very professional finish.
Muy buen trabajo, muy prolijo. Gracias por tomarte el trabajo de publicar un vídeo tan detallado.
Beautiful! Great video thank you.
Well done on the build and video. Finished boat looks great
AKA Nathan
thank you for this wonderful and insightful journey.
fantastic --very inspiring--well done
Super job, well done!
Great WORK! A very fulfilling experience I would say! ! !
Thank you very much and great Job. I'm not building a boat but something like a camper shell on the back of my C4500 Kodiac that has a flat bed that we carry wind turbines on and want to protect them. It's going to open up on top so the turbine can cantilever up and out for show
Magnific !!!! Congratulations from Argentina
Outstanding, thanks for sharing!
Amazing workmanship
Great job. Thanks for sharing!
keel and centerboard...quite profound...like the entire process!
Fantastic journey, enjoy!
Inspired, inspirational.
Impresionante!!! que bonito acabado... Gracias por compartirlo.
well done & nice video doc. enjoy
great job, the sailboat and the documentation... usefull
Very useful! Thanks a lot for sharing this!
While I appreciate the time and effort that went into this project, I'm stunned at the waste of time and money. There's a plan for building a Minicup 12-foot sailboat on the internet made of 1/4 inch non-marine plywood which can be but not have to be fiberglassed for additional strength and durability. I built one in my garage in two weeks and did not fiberglass it. I water-tested it among a fleet of Sunfish sailboats and it was much faster and drier. It's an incredible boat and you don't have to tear walls out to get the boat out of the house. It's flat enough to go through a standard door. I suggest before tackling a project like this that you try to find plans for the Minicup on the web. Last time I looked, they were free. It's a a great little sailboat that you can have sailing in two weeks or less.
Great video. Very helpful.
awesome build
Nice job; Buen trabajo. Gracias for sharing, dude...digo ...colega.
Tremendo Trabajo!!!!! Impresionante
Congrat, nice work. Fair wind always!
It will defiantly encouraging me to start build up a ship. as wall as small yacht.
Wow! That is the first time I see a boat with no stern stay afloat.
Funny !
ever see a sailboard ?
+Richard Beauchamp The open transom style is mostly used inshore choppy water on some faster boats. It helps get rid of foam faster. Its a specialized thing. Most boats have a transom.
muy inspirador!, felicitaciones!!
Like an artist at work mint!!
Nice job.
For your next resin work and for other builders: You should use nitrile gloves, the chemicals will go through latex. I sometimes use thick (longsleved) Nitrile gloves and one way Latex over them. Working indoors you should also use some respirator. Thats a lot of dust.
18 people gave it the thumbs down? wtf! Great video, 332 say thumbs up, enough said.
Those 18 people probably were astounded that anybody would spend that much time and build such a small boat.
Fantastico, well done.
Its incredible but I think this is the only youtube video about a complete proyect
Great job!
Thank you for posting this video. You created a beautiful boat that I'm sure will creat many fond memories.
I have a few questions:
•. What is your estimate of the final weight of the boat?
•. All in, would you share what you spent on materials?
•. Approximately how many labor hours did it take to complete the project?
•. Did you have any trouble sourcing the sail?
•. Now that you have been sailing this design, are there any modifications you have done or would recommend?
Again, thank you for posting this video. It really has me thinking about doing a similar project.
Well done
Here in the states foam sheeting can be found at low cost at Home Depot. Just be sure that it is closed cell foam otherwise it may degrade in a marine environment. Also, make sure that epoxy will not melt it. Some foams will literally melt like ice cream when laminated with epoxy. Easiest is to do a spot check using a scrap piece.
Muy buen trabajo!
You should be proud of yourself, I see that you used a computer software to draw your boat and it's all right.
I learned on the drawing table , I couldn't do anything until I told myself ''it' already there' ,then I drew my baseline from wtich all the other lines came from and it came to live; from the imagination. We are like god, we can create!
Very good video.
great job!
very useful indeed, thanks for sharing.
Good info. What type of foam and how thick was it?
thank you. Nice video
cool build...
Nice foam skiff
Thanks for sharing .
beautiful.... thank you.
well done,but you were worried about damaging the floor then started to demolish the house
Great job!!!!!Where did you get the boat plans?
Nice Work
Nice class !
Just came across this video looks great
Where did you get the plans>??
please advise
Merv
fiberglass and resin....will last forever!
un trabajo exquisito y muy buen vídeo!
pero porque pones peel ply si no aplicas nada encima de este?para dejar la capa peinada o eliminar exceso de resina?
Awesome thanks
i found this fantastic, thanks for posting. what is the name of the foam product how thick please.
Gracias por el video...excelente trabajo. he estado pensando en hacerme un "row boat" de este material, pero no se que tipo de foam es, ni donde se puede adquirir , vivo en España.
noticed the speed record was set with a mast and sail parallel to the hull...more of an outrigger...any thoughts?
how many hours and how many $ did it cost you ?
what is the wood you are using for the frames?
2nd time on my life that i witness the fall of a wall because of a boat, nice job anyway!
impecable muchas graias por compartir, el diseño del casco es de uds ? mastil y velas de 470 era para probar o queda si , ? saludos desde Argentina
Looks good! Where is the transom?
what foam was use in this project..
What type of foam is that?
That was cool
How much did the boat weigh ? What was it's length , width, draft ? Did you feel you should have made the deck deeper because of it's self bailing nature ?
God job
Was the boat involved in breaking the door frame and wall at 10:30??
hola que trabajo brillante.... que nombre tiene la musica del video...???? felicitaciones
You were so close to making a nice sporty boat.
Then THAT rig? I hope you developed your fittings and rigging after the video
I wonder how much it cost him, and how long it took him to finish?? Have you guys have any estimate??
I try to Google what is HDK putty for liming foam plates but I did can't find any product what is HDK PUTTY and which producents have it?
Cheers
Would this type of construction work for a camper shell?
Second Act I probably use aluminum tubing
Second act, It does work, I just built a van top camper on my chevy express 1500 I used 2 " xps board from the lowes. Put a layer of 10oz cloth with epoxy on the outside and some bed sheets and regular house paint on the floor inside, and I also painted it with acrylic house paint after fairing it with lightweight spackle, it looks nice and very very light.
