A lot less as that boat won't see any air if it hits a wave.Also there is a big difference between 60 and 80.

You are trying to split hairs here. Both boats have huge decks, and more feet of joint than I can even guess at. You have a 16000 lb 400 SS, and a 10000 lb 382. Neither is a lightweight, and both are going to do a lot of stressing of that joint. Even if the decks are the same length, the 400's is 3 FEET wider. Thats about 40% wider than the 382.

we run our 292 very hard and have yet to see a problem..knock on wood. its a 2003.

I talked to Formula today at the boat show,and while they say they have never seen it happen if it did its driver error....I told them that if the fiberglass broke I would agree but if its the glued joint I would not.One thing I did find out is the hull warranty is 10 years not 5 as stated earlier in this thread so depending on date the 382 in question was put in service it may still be under warranty.If so it should be towed to Formula and let them deal with it.

The guys at the show were telling you what Formula's hull warranty is on todays boats. They were 5 year hull warranties through 2004. In 2005 they went to 10 years. This is stated in the 1st letter from Formula in this thread, and I just went through my 2001 Fastech catalog from Formula which says the same thing.

Actually they said the 10 year started in 1998,but if your brochure says different that is probably correct.

Mine go back to 1995 when I bought my first one. The 2004 (and prior) one shows 5 years for everything. The 2005 shows 10 for structure and 5 for mechanical.

If its 10 for a 2001, then this 382 is right on the line depending on when it was bought. I would think that the letter from Formula on the 1st page of this thread would have said it was still in warranty, but it said it was not.

Driver Error?
 

That's an interesting response. Lets see. Throttle down, steer,mmmm. 5 boats, same club, all broken seams, same issues. Yes Driver error I'm sure thats it! It surprised us all that Formula did not seem to take this seriously, mine is the newest at a 05. I was reimbursed at a "percentage" of the repair. I never read in the hull warrenty that there was a owner share in structural failures. In this day of safety first I would think a problem as serious as this would be spearheaded by the factory instead of posted by a owner as a courtesy to fellow 382 families. These deck joints were not properly fitted from the factory in our opinion. In my case the plex was not applied in enough quantity and oversqueezed according to the installation info from Plexus. I hope Nort was helpful in passing this info on to perhaps prevent a tragic failure in the future.

I'm sure someone at Formula knew some boats had these issues, and they implemented a manufacturing change, or perhaps just did them more carefully. When you double the length of your hull warranty, it usually is done for a reason.

It would be interesting to check the hull numbers of boats that have this problem, and see if they are in close proximity, indicating a period of time, or even a specific build team.

I don’t know if there is any correlation here, but the brochures say the weight of the 353 was 8575 through 05, 9100 in 06, and 9500 from 07 on. Also, I have an old boat test of a 03 where the top speed was 85 with 525’s. The latest boat test of the 353 clocks in at 80 with the same power. Maybe they did beef things up when they extended the warranty.
