Waterline
Also: waterline
The waterline is where the water surface meets the boat. Its length largely determines how fast a boat can be.
The Packrafting Store writes that hull speed depends mainly on the length of the waterline. Long boats such as the MRS Nomad or boats with an extended stern are therefore faster than short, round packrafts.
