it would last a long time, depending on the foam you used. 2 part foam is sold by weight... lbs per foot cube, the higher the denser. a good range of weight would be 2 lb foam, do the math for the weight of the dinghy when filed with foam. now 1 pound or even lighter would work, but it would break down under impacts pretty quickly, basicly it would bruise.
now if you could do some sort of foam rubber so it has some spring back, it would do well, that way it would not get "bruised".
the foam idea is nice but it would be pricey and heavy. the below link has prices and each density has its properties listed, ie how dense, stiffness etc

edit t37 if you get rid of the dinghy let me know, i real dinghy even with leaks would be better than what i have
