Hull Holes

We thought this was really interesting!

YachtingMonthly's Channel - YouTube

YachtingMonthly's Channel - YouTube

Himself was inpressed by how hard it was to make the hole.

We were both alarmed by how fast water could come in.

I was happy that what I have been taught and would do, were rated the best options, pretty much. (Tarp warped around the outside, cushion and locker board against the inside)

Re: Hull Holes

The plywood with the glue would work if you have a drill and self tapping screws. You would have to have the sizes for the drill worked out before hand, the cordless drill fully charged and the screws in a known place.

How are you gonna bend the ply to the hull shape? What if a structural member is in the way? Self tapping screws will break off in fiberglass before they tap in.
A good fothering sail and some underwater epoxy are your friends here. The screws might help if they can hold a piece of ply long enough for epoxy to set...

Re: Hull Holes

Well, I read an article a few years back where a couple saved their boat in the Caribbean when the hull cracked longitudinally. They used plywood and 5200 and a drill and either self tapping or wood screws (I don't remember which). So I know it works.

Have you ever tried wrapping a sail around the hull? Have you ever tried it in rough weather on rough water? Well, try it and let us know how it works.

The patching in the video is meant to be a temporary save-your-ass immediate solution.

It seems you were suggesting that your method was a safer choice. Pardon me if I'm incorrect in that assumption.

Re: Hull Holes

For small holes as in the video, jamming plastic garbage bags in with a stick works very well (BTDT)

Re: Hull Holes

I liked the board with a cushion trick and would be weary of using any spray foam or anything that would mess up the bilge pump.

Re: Hull Holes

my class for my captains card included working a sail over the hull to cover a "leak". but since there was no actual hole in the hull it didn't have the immediacy and impact of this demo. I have been told that a cushion and locker cover pressed up against the inside of the hull over the hole will slow the flow while you mess around with getting the sail or tarp in place.

The advantage of a response that needs neither power tool or fiddly bits like screws seems advantageous to me. I don't do fiddly bits well when functioning under a HUGE adrenal surge.

Days like that I live by the KISS principal!

Me too. But I would really like to hear from a couple who managed to get a sail wrapped around their boat and managed to stop the leak while at sea in rough weather.

Its like the emergency rudder debate. I have seen some that, I feel, would be almost impossible to rig in anything over 2' waves. They are tested at the dock and deemed a success. Try that same thing in 8' waves, then call it a success.

Re: Hull Holes

Thank you very much for posting those links! Did anyone figure out how fast the water was coming in? I think the fellow said that the boat picked up two tons of water in seven minutes. My rough calculations put that at about 4300 gallons per hour. I think I'll install some bigger pumps.

Re: Hull Holes

Capt. Hornblower used a frothered sail to plug a shot hole. Unfortunately the cargo of rice had already swollen and caused the seams to open. The ship sank anyway. Oh wait, that's fiction. Never mind.
