Power/Speed usage online calculator

Hi everyone,
let me introduce a useful tool to determine required power to propel a boat at different speeds.
I already posted a link at "Replace Diesel with electric engine" thread, but there are many pages already, and it is not easy to find it.

Required input parameters:
1) Boat waterline length, measured in meters
2) Boat loaded weight (displacement), measured in kilograms

Optional parameter:
1) Boat usable battery, measured in kWh

Of course, the calculation is approximate, because I use basic parameters only to calculate. Accuracy in most cases 80%+

I hope this tool will be useful for someone


P.S. It calculates monohulls only in displacement moving mode.
