The Land N Sea is billed as positively floated...unusual for a 28x8 boat. There's a minimum of 2" of foam in all the walls, more in the roof and the bilge is also foam in all open spaces. I haven't run into any wood except framing for the aft door and it was a joy to rebuild - dig out the old, fit and epoxy the new between the outer and inner skin. The transom is also part wood, but it's not sandwiched, the wood is exposed inside so a transom rebuild wouldn't require a lot of finesse.
The insulation is so good, that with 4 adults, 2 dogs and a 2 year old we need to open windows to cool off in 60* nights...but the roof a/c does a great job even in 100* temps.
Just a few reasons why I've grown to love this old girl.
