The Fin

Mick Mackie's sidecut keels: 8" of base under 4.7" of depth, swept back hard, for fish that get surfed down the line.

Mackie has spent two decades on twin fins and fish-type craft, and this pair is the most extreme keel of his that True Ames makes: 4.715" deep on an 8.00" base, 23.47 sq in, with a pronounced sidecut in the trailing edge and a lot of rake. Solid fiberglass, sold as a pair, fin system chosen at checkout.

How that reads

The base is where the drive comes from and the depth is where the drag comes from, so a keel this long and this shallow makes speed and projection down the line while sitting the board low in the water. The swept-back profile draws the turn out rather than pivoting it, and the minimal depth is why the fin will still break free predictably when it is pushed past what it holds.

Who it suits

Fish and other wide-tailed boards, and the kind of wave that rewards them — a long drawn-out wall or a pointbreak. On a board you want to surf off the tail in the pocket, this is the wrong fin; it is drawn for trim and speed.

If this is not the one
