Ok, that post has me afraid. Now I want to inspect inside my 30-year old 5.2 hulls

Yeah, that isn't cool, looks like I have some looking to do also, but I am pretty sure my bulkheads look different than those do.

i think it is a good idea to take internal digital pics. not like it costs anything. Even if it is only to understand a little more about the internal workings. That thread really tells you you need to keep an eye in the innards, esp on older boats.

not too sure but i assume those are australian made nacras and the bulkheads may be different on usa made ones. esp as it seems there were 3 different bulkhead types used over there

i,ll try and post some of the pics i find of my 1982 hulls so we can get an idea of what differences there are. the more different years we can get the better

I have an 81, I just checked all my bulkheads and they all look good and have no cracks and are attached all the way around.

i wouldn't kick yourself too hard airborne, from the look of your pics your hull failed just forward of a solid bulkhead
don't think a digicam down the inspection ports could have picked up any signs of impending doom eric e

Actually all the bulkheads are very solid. The stringers in front of the bulkhead on the outboard side must have been delamed. The reason I say this just under the stringer flange was dirty like it has been seperated for a while. If you look under other stringers the flange is clean like it just became delamed.

which makes me wonder how difficult it would be to lift those decks for an inspection, as the aussies did to repair the 5.8

maybe i'll just have a careful feel/flex around first

3 years ago I reworked the interior of both my 5.2 hulls; in front of and behind the front cross beam. Delamination of the stringers is quite common in boats of that age. I reinforced all stringers and installed 3 bulkheads in each hull in front of the forward cross beam. In addition I installed bulkheads immediately infront of and behind the dagger board wells.The decks were easily removed, a lot easier than my P19 was. In the end I added about 6 lbs per hull.

Do you still have any parts to your Nacra? If so, please let me know.

Wow it looks great. It kinda reminds me of another one, but just can't remember where <img src="http://www.catsailor.com/forums/images/graemlins/grin.gif" alt="" />. Glad I could help out.
