The Fin
Jeff McCallum's modern keel: a traditional keel base length with added rake and less area, in solid fiberglass on Futures bases.
A pair in solid fiberglass, in charcoal, 5.0" deep on a 5.9" base with a flat inside foil. McCallum kept the base length of a classic keel, which is where a keel's drive comes from, then added rake and took area out of the body and the tip. What is left still runs down the line like a keel but does not have to be pushed all the way through an arc to get round it.
How that reads
A long base drives the board forward and gives it a settled, fast trim. The added rake and the narrower tip cut wetted surface, so the fin releases at the end of a turn instead of tracking on, and it will change direction without a big committed arc. Against a full traditional keel it gives up some straight-line hold in exchange for release and a shorter turn.
Who it suits
Wide-tailed boards and fish shapes — the craft a keel is normally cut for — ridden by someone who wants more turn out of them than a classic keel allows. Twin fin surfers after keel drive without the tracking that usually comes with it.

From True Ames
An upright template with a modest rake and enough base to hold a line, set up to keep a wider-tailed board from washing out in the turn, so the board redirects off the back foot instead of arcing around.
Our take
This is the twin you reach for when you want a fish that surfs with rail authority rather than drifting down the line: it tightens the turning radius and gives you a real top turn instead of a long carve. If you want speed and hold over pivot on a wide keel tail, the McCallum Keel pulls harder.
