Adding Floatation to a NACRA

Does anyone know of a good way to add floatation to a NACRA? Got a big hole in my starboard hull on the 4th of July a couple of miles offshore in the gulf we made it back in ok but that hull was underwater the hole way back. Its got me thinking if I hit something that breeches both hulls that boat will likely sink entirely. Its a 1990 Nacra 5.5sl Edited so Andrew Scott thinks Im cool! lol!!!

Checked my boat there is not any floatation in the hulls. Any suggestions on what I can add for floatation that will fit thru a 4" inspection port? I though maybe those pool noodles or something like that.

Whatever you do--DON'T fill the hulls with foam! The foam will retain water and destroy your hulls from the weight.
Noodles are good and light--and won't make any noise clunking around. If you could get some bladder in there you can inflate, that would be good, too. Air is the best floatation.
You can get packing material that is really just air packets. That would work, too, but I don't know the durability of the plastic.
There has been a lot of joking about filling the hulls with ping pong balls, but that isn't a reality. I just get a kick out of envisioning the slick of pingpong balls it would make if the hulls crack in half!
packing peanuts would be just as bad!

Yes it would...maybe someone needs to come up with one of those self inflating devices? 😆 a hydrostatic release so if the boat goes down a few feet it activates and floats back up!!! Thats how some life rafts activate on ships.
As for pontoon boats I often looked at them and would say if I were to get a petro chugging, BP mess making boat it would either be a pontoon boat or one of those Chris Craft style wooden boats $$$$

Todd & Frank helped me patch that but I still have a real slow leak. The next thing we are going to try and add some filler to the resin and just paint the dagger well with it. But as I said the leak is real slow so I can sail it as is for now. I adjusted my mast rake and moved my weight forward last sail and it sailed like a total diffrent boat I was surprised of how balanced it was when flying a hull. It just felt right! When's the 6.0 coming to 10 mile?

I wish it were there right now! This weekend is San Antonio for a show...It just seems to go on and on. Glad your able to hit the water. I'm afraid I'm going to have to dial in my boat (and me) all over again. IF I get to head out, I'll definitely give a shout.

HA! At 7 bucks a tube - Wally world looks like a better alternative. The pool noodles are about 3" dia, so it should have enough room to bend and get them into place. So you adjusted the diamond wires for more agressive rake? Do you know what tension your running?

Well NMMA requires 10% of "capacity" of a hull to be in flotation. I dont think that's the aim on this though. Pfd's would cover occupants and the balance is just to keep the boat in a neutral boyancy state. My boat is 420#, and its actually pretty hard to "burp" all the air in the chambers - So to answer your question - I have no freakin idea 🙂
There is another product other than the "pool noodle". Polyethelyne foam would be more quantifiable in its flotation factor, as its used currently in the industry for this purpose.

A testament to Nacra buoyancy:
A few weekends ago I took four people out into Lake MI with 15 - 20+ westerly's. I rushed the set up to accomodate the scedule of one of my crew. (He only had an hour) We were out ripping for that hour (two on the trap) and as were were heading back to the beach my wife asked "Why is the boat sinking?" I then felt the plugs in the pocket of my vest! I had everyone go forward and we landed safely. It took 6 guys to ease her far enough up the beach to drain the hulls which were full.
