FAQ

What is a block coefficient?

The ratio of the hull\

Why does a boat sit deeper in fresh water?

Fresh water is less dense, so a greater volume must be displaced to support the same mass. The change is small but enough to matter for a vessel with limited clearance.

Is this accurate enough for stability work?

No. This estimates displacement from bulk dimensions. Stability, trim and loading calculations need the actual hull offsets and a naval architect.
