I have and use a modified Hobie system on my boat and think it works very well.

I think the Nacra system is the best for going through surf, but is not as good once you are out there. Notice that many of the HT's in the Tybee 500 had a knock off of this. However some had a different system that worked in a simmilar manner.

The stock Bimarre system is kinda awkward to work and probably tough to get down while trying to sail through surf.

I like the simplicity of the Inter system, but laks a little in the "beef" department.

The Prindle rudders lock down well, but getting them locked and unlocked was always my biggest problem.

For sheer elegance, you can't beat the Marstrom T-boat system.
