waterline length , LWL (abbreviation)

Vessels that have this type of hull travel through the water at a limited rate which is defined by the waterline length.

The boat has a waterline length of 90 feet and is 127 feet on deck.

Most boats rise outwards at the bow and stern, so a boat may be quite a bit longer than its waterline length.

They travel through the water at a limited rate which is defined by the waterline length.

Its overall length is 7.87 metres for a waterline length of 6.03 metres.

For vessels with displacement hulls, the hull speed is determined by, amongst other things, the waterline length.

"San Diego doesn't plan to lose the cup to a 90-foot boat," he said, referring to the waterline length of Fay's new yacht.

It was supposed to extend the boat's waterline length and therefore its potential speed.

These boats have long overhangs which allow the waterline length to increase as the boat heels over.

As the yacht heeled over in the wind, more waterline length became available thus increasing theoretical hull speed.
