A moze ktos z kolegow przetlumaczylby to fachowo na polski?

This form allows you to calculate the theoretical maximum speed of a displacement hull. This is an approximation, and boats may occasionally exceed their theoretical hull speed for brief periods, as when surfing down large waves, or when temporarily planning in unusual conditions. Also, this limitation generally does not apply to multihulls, though they are technically displacement vessels.

*Hull speed:

This is a useful rule of thumb for determining the relative "Heaviness" of a given design; in other words, is the boat heavy for its length?
- over 380: very heavy
- 320-380: heavy
- 250-320: medium
- 120-250: light
- 50-120: ultralight

*Displacement
to length ratio

It is the measure of power to weight. Though the speediness of a given boat is determined by a host of other factors in addition to this one, it's still a useful comparison tool. Other factors being equal, the boat with the higher ratio will be the faster boat overall. Boats with sail area/displacement ratios below 16 will generally be fairly slow. Boats with ratios over 22 will be very fast, and some extreme multihulls will have ratios over 30.

*Sail area
to displacement
ratio

The Capsize Screening Formula was developed by the USA Sailing Association as a rough rule of thumb, helpful in comparing the initial resistance to capsize of various boats. Boats with a Capsize Screen factor of 2 or less will have a normal initial resistance to capsize and will in general be safer offshore boats than boats which exceed this value. The lower the value, the better.
