I love this video... Your ability to put a positive spin on lesson's learned is fantastic!!! The songs you chose couldn't have been more perfect (had to watch & listen multiple times). Great job getting out there and challenging yourself.
Thanks for the interesting video Koon. Experience with my Mirage on Great Lakes in Canada is that the big leaker is the front hatch. I proved this by putting my phone inside on video looking up and spraying water on the hatch from outside. Following tips on Hobie forums, I got rid of the outer gasket on the hatch lid, then added some 'formed in place' silicon on the underside of the lid where it was not meeting the hull gasket properly. Also replaced the bungee and made it pretty tight. It's still not perfect, but much better. My Hobie is about 2016 - perhaps upgrades to the design have been made since then.
Thanks for taking the time to share your experience 🙏. You are right. One reason why I failed to notice this for a while is because the hull will actually flex and twist which will create wider gaps for water to seep through. One solution is to use a inflated 14-16 inch tyre tube to tighten the hatch seal.
Wow awesome video. I had a crack in the drive well only small but after an hour would be quite a bit of water. Sealed it up with poly beads and glue. Series 1 Tandem island. Thanks for the lessons
Hello Koon Wei, Thank you for this fantastic adventure! I also own a Tandem Island which we sail in the US Great Lakes, Atlantic and Florida Keys. I mostly live in South Africa where we have warm weather like you do. I loved your musical choices for this video. So sorry about your battery and gear. The salty sea is a tough mistress! I salute your great adventure. It is amazing how quickly you took that water aboard, and also how you were able to make headway with the mirage drive despite all the water you took in your main hull. I think the surf board also helped your flotation along with the amas and akas. How does your jib perform? Its great to have somebody else to adventure with on another Tandem Island like you have. I usually go with one of my sons. If you ever are in the US I would love to sail with you! Keep up the great video and hope you and your friend will have another chance to make it out. I loved how you ate your provisions the next couple of days and how you were able to chow the noodles and make your cofffee when you finally made shore. Kind regards, Rick Gutierrez
Dear Rick, many thanks for your kind words and encouragement. I made some enhancement to reduce water seepage via the hatches. I love to head back to sea which I havent done for more than a year. Maybe next month I will have a break. The jib is good but the fur-roller need more reinforcements and probably need a line through the mast rotator towards the rear rudder to avoid entanglement when I fur the main sail. By the way, I have a friend with the same last name. He was from the Philippines. If I ever have a chance to visit South Africa or the Florida keys, I’ll buzz you 😂.
The boat is sailing above the water. The sea water barely splashed up the stern of the boat. Even if that channel's waterproof seal is worn out, but it is still above the water. How did water get in? 🤔 👌 You are lucky to be safe. Thanks for Sharing. 😊
thanks for sharing, and glad you got back safe. I learn a lot on this video., bounce back stronger 💪😎🏝🏖 maybe float bags can help but i imagine you dont have enough space inside your mirage . good luck next time.
Thank you for posting this. I was in rough conditions with the same boat and sprinted to the nearest safe landing because I feared this exact scenario. We emptied a few gallons and continued but wish there was a better way to empty the sealed hull, improve the gaskets and what not. Glad you made it safely!
I have about 80 1+1/2 liter sealed plastic bottles stuffed in the hollow areas of my Hobby Mirage so that if I take on water, I can still sail (slowly) back to port.
I thought so too but water leak from rudder cords doesnt appear significant during the test. But during rough conditions I cant say I am 100% sure that is not a contributing factor.
I don't think the twist and stow hatches were designed or positioned to be water-tight when submerged. The gasket-seal is more to prevent water intake from rain, splash, etc. Water also enters from the steering line openings in the hull if the stern gets submerged. What caused the rear of your TI to initially submerge? It is possible, of course, to simply overload the boat beyond what it was designed to carry.
Sorry for not responding earlier. Thanks for sharing your observation! The overall load was less than 200kg with a margin of safety of at least 50 kg for TI. The initial launch footage should show the good boyancy with rear and front above waterline. I have since cast suspicion on hairline cracks that could widen under hull stress conditions during bad weather and rough sea conditions as the next most plausible explanations. This could also explain why nornal leak test could not detect. Probably requires inch ny inch close inspection of joints and sharp surfaces which I havent done.
Yes, when I noticed from the rear seat that water was flooding the kayak, I had to make a call between stopping to bail out water or contine with the momentum towards the shore. I made a bad call to go on. And the subsequent speed of sinking caught me completely by surprised. And I had to move to the front seat to continue paddling as bailing water is impossible with the hatching below waterline. I am fixing a tube where bailing with a bilge pump is possible without having to open any hatches.
Thanks 🙏 but I didnt overload on this trip. If you look at ua-cam.com/video/m0OSf337BGY/v-deo.html this trip, much heavier load and stormy seas but no flooding at all?! Or perhaps lucky on that trip.
@@raydavies2545 not really to be honest… I patched what I could find but cant explain how the flooding occured to suddenly and within such a short time, like 30 mins. As said, I took far heavier load with no issue earlier. One remote possibility is a crack somewhere or front hatch has a gap that only manifest when hull is under certain stress conditions.
Yo da man! I guess your MPA meant PCG(Police Coast Guard). I kept wondering where were they when they most needed untill I saw them later in your video. Still can't comprehend why they can't help tow. It says a lot about you when you single handedly pedal & retrieved a submerged kayak back to shore. Sadly, likewise too for our well equipped PGG. Proud of you! Those rubber seals will harden over time. I had a Hobie Sport for 11 years.
Thanks Dan. I never had such leakage problems with my AI which I used for 9 years before selling it off after I ordered TI. Please note that MPA is Maritime & Port Authority of Singapore. They look after sea traffic like our LTA for roads. Police coast guard is like our traffic police but with focus on general border security, illegal trafficking. I fully understand MPA have their protocols to follow and they are already kind to escort me patiently. MPA will be happy to rescue me but not my kayak. I am fully responsible for my own actions so I should try to recover the situation on my own. The only other solution is to engage a small operator to tow the kayak but I was cautioned by the crew in Sea Matrix that I will be ripped off.
Towing a small compromised vessel like that can actually cause it to sink when it is pretty close to neutral buoyancy the drag could easily pull it under. the slow muscle method prob saved the day.
Hardshell usually more efficient and hardy. Inflatable is probably good for shorter distance or as lifeboat. I like inflatable for the lightweight and convenience.
@@koonweing thx for the reply, yes the inflatable may be deflated overtime while the 12v pumps are just getting smaller enough to be used while traveling. Then you could have all of the benefit of the inflatables without it's biggest con 😁
No I havent install a pump. Just wasnt expecting such a rapid flooding without any hull breached. I thought I could bail the water out when I got to the destination.
You had too much stuff on that thing, including solar panels - useless where there is no clear sky. Replace those and the motor with a good paddle or set of oars!
@@koonweing, you must have had good reasons to take everything with you. By comparison, I had less stuff in my boat - while I had everything I needed - during my 8-week rowing trip a few years ago. Did you lose anything? What was the cost of the damage? Such trips are great because they teach you what you can learn in absolutely no other way.
So many solar collectors? You also get electricity with a water turbine, you raise the sails, on the side of the blade they turn a small 12 v alternator. Kayak drilled like Swiss cheese, some parts in the kayak are filled with pure foam... Today, the Chinese produce all kinds of electronics... This is expensive, stupid, frivolous.
Thanks for the video Koon Wei, very helpful, to new owner like myself

Great minds think alike. I thought of that actually but then I cant carry my cargo. If I cant fix the leak, I have to install an auto bilge pump.
Some leakage of a heavily weighted TI can occur throught the rear rudder cord holes. It's hard to seal those completely without restricting the cords.
I thought so too but water leak from rudder cords doesnt appear significant during the test. But during rough conditions I cant say I am 100% sure that is not a contributing factor.
Luckily u are safe! Loved your adventures.

I had a crack in one of the cup holders I filled the kayak all the way to be able to find it .
You could see the troubles earlier on with water coming over the front easier and easier as it started first taking in the water.

@@koonweing that's odd. Josh Holmes worked out how to install an external bilge pump for those situations.
@@koonweing And did you find out how the water leaked into the boat in the end? Was it a failure of the hull?

Woah!! exciting stuff Koon wei!!
Hi U...
Where did you get the 4.4 furling genoa from?
LOVE IT.
Made it
@@koonweing can you please show how??
@@ParabrisasMotocicletas ok next video 🤣
Good thing it is designed not to sink. You put all that extra weight (solar, battery, fridge) just to keep your poison (Coke) cool. Priceless!
Maybe install a bilge pump?
It is strange to have batteries on board and not have an automatic bilge pump.
Why so many solar panels. You can't require that much power. Why did the craft submerge?
OH NO, WE'RE SINKING WE'RE SINKING... 🚢
German coast guard……. What are you……. Thinking ?
When is your next adventure trip?? Got few kakis on AI & TI interested :)
8th Dec - Pasir Ris to Ubin camp overnight… 😅
去时候好好的 回来变潜水艇了😂😂😂注意安全

Mamá, hazme grande porque boludo me hago solo ! 😂😂😂😂
Wow, adventure of a lifetime dude. I'd shit my pants if I have to pedal back to shore. Lol
Despite all preparations, there is always mistakes to learn from.
Don't you have an automatic bilge pump?
You have tone of power on that boat.
Or was the leaking too much for the pump
No I havent install a pump. Just wasnt expecting such a rapid flooding without any hull breached. I thought I could bail the water out when I got to the destination.
This looks like a big WTF
I think it's time to add a 500 gph rules bilge pump. So unfortunate, but a great life lesson.
Ordered!
40.00 sump pump could have avoided this mess. sucks for your stuff to get ruined
800w solar panels! At least you won't have any flat batteries 😅
Hoow are things?! Koon.enjoyed~how beautiful uploading!
Lucky not to bring my drone on this trip at the last minute.
RIP electric fridge...lol thats tragic
