Trophy 2152 WA (Boat Construction?)

Transom was laid up and then a big clamp to hold while it cured, then final glass over the top.
99% sure that all plywood was XL.....easier for purchasing and cutting etc (can’t confuse them)
Plywood was likely laid into wet glass and then overlaid with more glass

 

Sorry Gonzo, in nearly every situation......foam under the decks will do nothing to stop the capsize.......assuming the boat is not stable upside down (a big if) then if the boat flips the right way up (another big if) then the high foam will help keep it stable in the swamped condition......
Capsizing and stable when swamped are very different scenarios

 

Re-read my post. I stated "To keep a boat from capsizing and float upright when swamped"

 

Gonzo-anyone reading the thread caught ms error. Just so you know.

I think the bigger question is would the trophy have any such consideration. And I doubt it. Whether the OP can provide it or spaces allow it is another question ms can speak to...

 

Most boat manufacturers used foam under the floor and around tanks. I suppose that floating upside down is better than not floating at all.

 

Apologies, I misread it

 

Well, it is easier (read cheaper) to put foam under the floor......but I know some builders (Bayliner/Maxum/Trophy among them) always tested the boat to ensure it met the regulations, and we did some work with pre molded foams so that we could locate them under the gunwhales.....especially useful on smaller outboard boats. As far as the 2152 foam....it will not be enough/high enough for level flotation.
Interesting fact about foam, adding lots of foam (low and high) does not really work, you need the boat to float enough when swamped that the higher foam actually does something....too much foam too low means the boat floats so high that it must must heel too far over before the high foam actually does anything....and by then it’s too late and capsize is inevitable
