I have an 84 Nacra 8.5. One of the hulls leaks a fair amount. the tops of both hulls are soft. I think i know how to fix the hull tops. but i am looking for a good way to get inside the hulls to perform some repair. Is there any good documentation out there on the Nacra? Thanks

Take the decks of with a thin putty knife/blade.

I think they come off as solid pieces.

I am not sure if this cat is new enough but yes I think they cover large apertures.
I will go through my files to see what I can find.
right, I have these two photos.
I think the knife may be what was used and the blood tax for getting the job done. : )

That is awesome information. if you could find out the year they started those it would help. but I feel pretty good about just going forward. Do you know if i wreck one of the decks, can they be replaced?

Performance sells them but it is my understanding from another thread here that they have misplaced the molds (not sure if it is the same Nacra or not). I would suggest makeing a mold off of one of yours before you attempt to take it off.

Thinking about it, my boat may be to old for these access holes. Can i get the deck plates and then cut the holes? and then back fill? the cut out area?

Dave-

I don't know if you are squeamish like I am about doing fibreglass work but Aquarius is supposed to be the best in the area for repairs. Tom Haberman is who I've talked to there. But I'm squeamish.

Also if you're looking for people to sail with check out www.Fleet444.com We're mostly a Hobie Fleet, but we're open to other boats for any of the fun events just not at the regatta.

If your boat has deck patches like what was removed in these pictures, then you have these holes. There's no other reason to put on a deck patch unless there is a hole under it.

The pictures with the decks removed were from a Nacra 5.2. I have a 83 Nacra 5.2 that I removed the decks on for repairs. I used a chisel to get under the lip of the deck and then used a large knife and gasket scraper to get to the middle of the deck. If you have remove the rear deck, there will be a lot of resin around the daggerwell to break loose if your boat has them. Make sure Performance has decks for your boat. I still haven't heard if they found the molds for my 5.2 decks. I have found a used deck to install on mine though.

You have to beat the scraper/knife with a hammer to break the adhesive.
I'm pretty sure that the decks are made from a solid polyester/fiberglass lay-up with gelcoat finish.
If you muller the deck, you can take a mold off of the other hull before you get stuck into it

I am not sure of the tramp configuration on your boat but the Uptight Trampoline Tool works fantastic.
