[QUOTE="farmer4life, post: 503792, member: 34062"] 2 lb foam is lighter thus gets you 2lbs extra buoyancy vs 4 lb foam. Unless you need better structural support from the foam, I’d think 2lbs would be sufficient. Foam gives about 62 lbs buoyancy per cubic foot, less the poundage. So 2 lb foam is about 60 lbs buoyancy, 4 lb foam is about 58 lbs buoyancy. There are lots of threads on here about calculating foam needs. This one has helped me: [URL="https://www.tinboats.net/threads/how-much-foam-do-i-need.25283/"]*****HOW MUCH FOAM DO I NEED*****[/URL] However the link to the usgbc doc is broken. I found this link as well which was very helpful to figure out the calculations: [URL]https://safeafloat.com/wp-content/uploads/2021/04/F-_-G-_-H-Flotation-Final-4-14.pdf[/URL] [/QUOTE]
