How are you finding the Flow Fins on the mirage drive?
Better top speed, less effort etc???
Thanks.

Just the one flow fin on the rear and it is fabulous on the A.I. Helps with the tracking and also allows you to pedal effectively at greater speeds when sailing. I use the drive in the Outback as well and it makes it rock side to side a little when going hard, but I prefer it to the two turbo fins. Tried two flow fins but it was too much effort for my short legs. Not so much a higher top speed, more of a lower cadence, but a little more effort. I reckon the Outback top speed is capped due to the hull design.

Thanks Mav, interesting to hear from someone who has already tried it out, especially when you've used the same hull as I have for some of that testing. The outbacks top speed is definitely capped by the hull, my max without wind/tide assistance is 10km/h and my absolute max is 13km/h (caught the wake of a boat). Might just stick with the regular set up and turbos for now but can definitely see the advantage as far as the AI is concerned.

2015 model outback must be a hell of a lot faster than the 2013 model

might need to check that speedo it could be reading high

I reckon that'd be about right. I could manage 11km/h (GPS) in the Revo for short (30 sec) bursts and I'm not particularly strong, so I guess the Outback would be a little bit slower.

I guess the 20mm longer cranks would give more torque, but a slightly slower pedal-rate.

whats the single flow fin like with the AI in single hull mode? Does it rock more than the OB, I could imagine so.

Is it effectively like having a higher gear? Expect having longer pedal shanks would offset this to some degree.

The AI in yak mode doesn't rock as much as the Outback, might be something to do with the substantially longer waterline?

The longer cranks make the single Flow Fin about as much work as Turbo Fins. So a slightly higher speed I suppose, but I haven't measured the speed and not sure how I would actually measure the difference in effort it takes to push the pedals. Plus the more I use it, the more I get used to it. It is funny dropping back to turbo fins, it feels like there is little resistance.

The yak range is not designed for flow fins, so there could be warranty issues. The steel cranks shouldn't make an issue.

I've tested these to and I really like them. I have the same set up as Mav, turbo fin on front, flow fin on rear. However, they have to be thru-bolted. Forget about using the adjustment system Hobie have on the pedal arms with these, as they will cause issues, guaranteed. Have spoke to marty about this and the plan is to supply them with 35mm 8M bolts. I have used wingnuts on mine to maintain adjustment (going from lowest to highest seat position changes leg length requirement), but I'd have been almost as happy to use a standard bolt. SLH will have these available next week. Piccy attached

I had a Hobie pin fail pedaling hard in the surf. The pin skipped out of the hole and tore through the plastic covering the metal between holes. I went to standard 316 through bolts after that and was happy with them for a while. However changing between the PA and AI meant moving pedal positions so I went back to a pin arrangement. This time though I made a custom pin, longer than the standard Hobie one and as long as it can be and still move between holes. So far this new arrangement is performing well. :up:
