Default Re: 25 seafari questions - weight calculations

Quote:


I don't know how anything else is weighed. The USCG lists the net weight of a vessel as the weight of the volume of water the vessel displaces as loaded. It is mathematically the same as the vessel's displacement. But as water density can vary, the net weight can change, whereas the calculated displacement remains the same. Displacement is always calculated against fresh water at 59* Fahrenheit. (I don't know why it's calculated that way, but it's the same temperature used as a base when calculating "density altitude" in flying.

That makes sense to me, it was just the word net being used for an entire weight that conused me. I`ve read that the same boat will float higher in salt water than in fresh. That`s interesting...I`d like to test that theory one day.


I`m in agreement with the recomendations of Dave and Connor but I`m pretty sure nuthinfancy is set on a bracket and outboard. I believe it can be done if done right. Hopefully Strick will chime in as he`s really done his homework on this topic.
