Both of you were going to do ride reports, weren't you? I'm especially interested in the outcome of R D M's fin experiment. I hope folks don't mind the bump up of an old thread.
I haven't had any more luck after the tinkerings I described on the previous page of this thread - still way too much drag (poor foiling and and too much horizontal surface area I think).
I haven't given up though. I have another one on the go with a reduced chord and a much more gradual transition (in front or rear view) from the fin base out to the each of the fin "branches". Hopefully this will do the trick.
Thanks for the update. A more gradual transition from the base to the twin fin blades, sounds like it may be the answer to the drag issue. Glad you are still working on it.
What about as the trailer on a thruster? A quad with really narrow spread?
I believe Herb Spitzer did something similar to what you are describing. He can give you a response based on his experience, if he's looking in. I've not done any other setups than what you've seen, so cannot do more than speculate. That said, I don't see any reason why it would not work just fine. I've toyed with the idea of doing a quad, but it never got beyond being just an idea.
Airboy808,
If you make the conversion, be sure to follow up with a report back on Swaylocks, or on this thread.

Hey Bill.
I haven't had any more luck after the tinkerings I described on the previous page of this thread - still way too much drag (poor foiling and and too much horizontal surface area I think).
I haven't given up though. I have another one on the go with a reduced chord and a much more gradual transition (in front or rear view) from the fin base out to the each of the fin "branches". Hopefully this will do the trick.
Thanks for the reminder to get going again.

This is a bump up for OBXbuddha. This thread was a result of interest generated from the Falkenau thread. Hope it keeps your fires burning.

Bumping this up for ''Everysurfer'' and anyone else with a curiosity about the performance and validity of the ''Twingle'' setup.
