Reverse chine - easy to draw but a bit more difficult to describe.
The chine is where the bottom of the boat joins the side.
Most chines incorporate a spray rail - a horizontal section up to a few inches wide. These deflect spray and increase lift.
A reverse chine is where this spray rail is angled down and much wider than normal. The idea is that it should should trap water and air under the hull for lower drag.
The front end of a Boston Whaler is an extreme example of this feature.
Have a look at Ballistic 7.8 metre hull. This has reverse scallop chines. Quite a hard ride in a chop but amazing sea keeping qualities. This boat has nerver heard of "Chine Riding" www.ballisticmarine.com
