Ok, I'm done with that repair - going sailing before I do too much more. For those who haven't used it yet, this JB Marine Epoxy is top notch for thin coatings! I think, in my case, it may even take the place of gelcoat or other UV product, especially since I may paint the sides of the boat at...

Here is a Video of the hull holding air for 11 minutes. I know I've had it hold at least 1/2 hour - so I guess I am doing well in that regard... I put the deck plate in - and sealed it property. No leaks there. One of the leaks (but prob not relevant to water) was a screw hole in that brass...

Ah, a challenge! I know it holds for more than 5 minutes. But you are right - being super-sealed doesn't mean much if one good crack expands with weight and load and is under the waterline. Still, I'm taking it as somewhat of a challenge to get it as dry as possible. Do a lot of MF and...

Thanks! Since I had the regular cloth sitting around I used that (covered on both sides with epoxy) as the backing patch. Then I built up with two layers of epoxy and cloth, one of which layers is solid afix to the old hull at the edges. I cut a little cardboard to make sure I stayed with the...

To my knowledge there is only pressure - when dealing with air. Volume is only the size of the item being tested in this case. I'd stuck on my breath for now since I am sure it is at least 1PSI. Important note would be how bad the hull in question might be. Since mines holds pressure (from...

You are the man! I went sailing in very rough conditions (Newport 20 MPH gusts) yesterday and after 90 minutes there was about a full pint or more of water in the hull. Too much - considering how much I traced down leaks and sealed the boat. I had checked the boat over and over - BUT, some...

Luckily I had no tight seal where the air pumped in - so although the pump was set at 6, it was relying on me holding it into the hole which it didn't fight tightly into...... In any case, I probably put 2 PSI solid into it - I'll keep it to <1 in the future. I don't think it would have "blown"...

Pics..... of the pinholes in the bottom of deck/hull rolled edge of the trailer - including second story (no, the zip ties aren't all that is holding the wood- metal brackets). U bolts hold mast. Of the entire trailer - still working on it, but you get the idea. It's hard to find small trailers...

I can get to most of the CB trunk from inside also - it looks perfect but I will put a coat of something or another in from the inside and, do more sealing and checking on the outside of it. It really does look perfect - almost like flat copper lined (color) and smooth, except where it meets the...

Slight update - which may help some. Boat still holds air nicely - BUT, when hosing it off after soaping it, this did a better job of allowing soapy water to hang on the rolled seam - and I did find some very small leaks (bubbles) along the hull/deck joint. I suspect that's not all the tiny...

I just read a post from an aircraft guy (here) that suggested a very low pressure - AFTER I already used 5 lbs. He suggested 1 PSI. I think it could take a little more than that. There are some good videos on youtube of soap spraying. We can breathe up to about 14 PSI.....so my take is that 4-5...

Hey all - owner of new Rocket (sunfish type) and also ancient Minifish. The MF definitely gets some water into the hull. A one hour sail without any dunking (capsizing), etc. will see maybe 1 or 2 cups in there - yes, I installed one of the 6" clean out to the left of the dagger trunk so I can...
