@MISkier , valid concerns
Sound wise, experience steers me to not be concerned, as my supreme is also not cavity filled, by design, and has proven to be the quietest boat of our bunch with my other mods.
Level flotation issue, is admittedly a rationalization..
Foam always gets heavy, eventually.
There is 4" of foam under the top of the deck. so the boat will be recoverable I suspect.
I've been first to respond to a fairly new-at-the-time overturned centurion BW comp than never leveled, just the bow pointing up, the stern banged along the bottom to shore. So, it's not a sure thing level flotation is effective.
The foam that was in this boat, and many like its contemporaries today, was essentially already water. Pre sunk, if you will.
I put more air into it, so to speak.
It won't go down fast unless punctured.
Closed bow is a big plus on this model regarding stuffing it.
Gas floats...
Yes, all a calculated hamster wheel of rationalizations
Yes it may not float level all that long. but, will never bloat again either.
Replacing the foam was a serious consideration until I spoke more with other boat restorers, who seemed dismayed by their effort and temporary results, in all sorts of crafts. I didn't want to do this again on the same boat
@Ronny61 , good eye, yes plantation teak, atop 5/4 uhm, my bud says mahogany, I think it's meranti. We can call it mahogany, because he gave me those scraps from his deck project!
It is seriously solid, zero deflection even with the wide brackets and no support in the middle
So different than the springboard that it had
