[QUOTE="Bigkat650, post: 251063, member: 7270"] It's all relative... Search 'Specific gravity' either on this board or google, or click here: [url]https://en.wikipedia.org/wiki/Specific_gravity[/url] I have flipped my canoe dozens of times, and the only reason in floated was because of the foam... If you want to figure out what raw materials comprise your boat, you can calculate how much negative buoyancy you need to float--i.e. how much of the raw material weight has to accounted for in order to keep the boat neutrally buoyant, so it does not sink. It takes some math in order to determine the answer, and I calculated roughly what I needed--then added about 40% more to make sure I was set. Overkill is always the answer. [/QUOTE]
