I'm trying to figure all this **** out on my own, because, well, that's the fun part. But I have a few lingering questions. And probably a lot more to come, sigh.
I'm building a Class 5(ish) Y-Over design.
Here are my specific questions:
- Adjustable mast rake? I see some variation of this a lot, so how does the adjusting bolt actually contact the base of the mast? A metal sleeve?

- Chassis tubing. I gather that the legs are 6061 T6 Alu, roughly 50mm in dia with a 4-5mm wall. How about the steel chassis? It obviously has to sleeve the legs, but how thick should the tubing wall be?
- Where the legs and front arm are sleeved it seems like most designs are using just a simple keyhole slot and clamp joint. Since the tubes are round and there is so much stress on the system sideways, why don't these slip? Or am I misunderstanding the design?
- I understand a large part of the benefit of this style of frame comes from it being dynamic and flexing under load. Do I have to worry about over-building the chassis and making it too stiff?
- I already asked this, but I'm going to try out the Pugsley Large Marge (65mm width) with some 20mm thru axle hubs laced with regular bicycle spokes. Really hoping it works cuz damn them things are expensive!
- Also already picked up a 6.3m sail and 460mm carbon mast! Now I'm scared to toss it under the machine. :/
Here are my plans thus far.
Thanks a ton!
(And my closest sailing spot is a 9 hour drive away... why am I building this again?)
