Trapezoid Keels

I don't think they were the first to make fins like that...deforest said:
There are a lot of similarities between the trapezoid keels and the Greenough 'paddle' single fins he originally built for his windsurfers to put more of the fin into deeper, undisturbed water.
I've been riding these keels in a 5'3" Stretch fish:
They definitely have some 'whip' to them and almost load up like a flex fin does thru turns. They have a definite feeling of going through the gears on bottom turns which is awesome. I would like to get them on a bigger wave or more open face then the sloppy summertime surf here offers. I'd say they are a little looser than a standard keel of the same size, but seem to be equally drivey... need more time on them. Definitely look weird!
That's harsh. Vulcan is an independently-minded guy who's doing really inspiring (award winning) stuff. His trapezoid keels are interesting to me, though I've yet to ride them. Tomo and his father were inspired by Greenough and others when they made those cut-away twin fins. There's a deep, rich history here that must be taken into account.deforest said:
Hi5 to Vulcan for trying new things.

Here is some photos from MT's instagram. Looks like he was actually "riding" these fins himself back in the mid 1980's.
Surfcat created the hatchet fins as well as the tunnel fin even before roy stewart did. Roy stewart did break the sound barrier on an olo at raglan a few years backdeforest said:I discussed this with Mark Thomson. Greenough rode mainly mats exclusively since the late seventies. I've never seen a picture of Greenough riding a kneeboard, or standing up for that matter, with any of the types of fins like the one in that article Duffy posted. I think MT really perfected those fins and lots of other people have since tried to replicate them, but none really understand what makes them work. I heard Chuck Ames is a great fin maker, but I think MT has been in the game so long, and ridden surfboards enough, that he's really dialed in those fin templates (IMO). I've only ridden MT's powerdrive fins, but i'd be curious to ride some of the others and see how they feel.
