plane, planing boat

Plane rhymes with "main". For a boat to skim across the water rather than plow through it. Planing boats (hulls) are lightweight and have relatively large engines or sails. Nonplaning (displacement) boats are relatively heavy ones that cannot lift out, and their speed generally is limited to their hull speed.
