Hello all, this is my first post, but hope it’s not a repeat ( I tried to search, but couldn’t find anything). I’ve got an issue with a phrase I’ve heard, and I’d like you input. The phrase in question is, “tuflites float better”. I tend to go back to my engineering days, and remember that buoyancy is a function of shape, fluid density, and object weight. Clearly tuflite technology could produce overall lighter boards, but I feel like the weight of the surfboard is negligible in terms of overall weight (say 2lb board weight difference goes to max 2% weight difference on the lightest of surfers). The lighter board could be more responsive (different moments of inertia) but shouldn’t affect the buoyancy. So, what the heck do people mean when they say “tuflites float better”? My only idea is that perhaps the measurements listed on the boards don’t include the skin thickness which would add volume, in comparison to a blank that was glassed normally and had thinner skins.
Typed “density and buoyancy” into the search box and got this…

that’ll give you plenty to read and should answer your questions.
You missed density in regard to the foam in your query.
lots of people say they are too corky too, ride one and you see what corky means....
Buoyancy is increased when the board is lighter. The material of the core or skin is not important, as long as the overall board wheight is lower than a standard pu board. You read a lot of phrases like “eps floats better than pu”, “epoxy floats better than pu” or stuff like that. thats all bllsht.
Buoyancy also increases with the volume of the board.
