Twin Fin with Futures

I’m looking at making a 5’10"/5’11" round nose fish style board coming up this Christmas break (Third board I will have made!). I would like to have Futures on the outsides and a standard box inside so I can ride it as a twin or single fin. Future Fin’s only twin fin option comes with a trailer that I will not be able to use because of the standard box at the tail. Any ideas on how to utilize Future Fin boxes for a true twin fin?

I’ve thought about making the fins, but I would like to initially buy a set and maybe make my own later on down the road.

Rider info: 6’, 180lbs

Thanks in advance for any input!

They make a keel fin set in fiberglass.

Or just don’t use the trailer.
