The dolphin drives with it’s tail and pectorals so shouldn’t we look more closely at this part of the anatomy when we consider how it relates to surfboard performance?
Just thinking out loud, Rich
By the way, did you notice that the pectorals are very nice cutaways?
Guys,
The pectoral fins control ROLL, and PITCH. Drive is tail fluke alone. The DolFin however well intended, was a complete DUD, as it relates to surfboard performance. Not so the mid size “Brewer” fin, and to a lesser degree the deeper “Downing” fin. The Downing fin simply had too much flex, and did not drive out of turns well.
I like the idea… like Thrailkill explains though, maybe you need to consider the use of the fin itself… No point copying fins that have a different use…
I browsed through some more high speed fish such as mackerel, and i found an interesting fin.
The underside fin, near the belly… it stays vertical, and is stiff, with no muscular control , that is… i dont think they can expand it whenever they want.

The underbelly fin sort a resembles the rear fin of the FCS H2 set…
The fin sits in the middle of the fish, with water running in a straight line past it…
Maybe these sort of fins can be templates for the rear fins in thrusters or single fins? I don’t really know but its just throwing another idea out there.
… fins… wings… foils… birds… planes…rockets… possible sources for inspiration.
Hope that helps.
