With regards to the question about the clip-in pedals:
- Shimano SPD cycling sandals
- Cheap SPD double-sided road pedals from Amazon, flat on one side so you can still use sneakers, clip-on on other side. I figure if they rust out in a few years from saltwater I'll just replace for $25. I hose them off after each use and spray with WD40 and they are holding up OK.
- Pedal axle extensions like
https://www.amazon.com/gp/product/B0B4W ... UTF8&psc=1I had an old set of Mirage Drive pedal arms. Removed the existing pedal axles carefully. Drilled out the holes neatly a bit. The hole needs to be drilled to just the right diameter to accept the pedal threads. Then used a bench-mounted vise to press and carefully thread the pedal extensions into the Mirage arms. This took some finesse and patience. The pedal extensions are much harder metal than the aluminum arms and so they will cut threads if you are careful, applying significant pressure with a vise and slowly turning with a pedal wrench. Then thread the clip=in pedals into the extensions. The width between the pedals is perfect, very close to a bicycle.
I have hundreds of miles on this setup and no signs of failure, it seems rock-solid. Makes for a much more pleasant pedaling experience. I think there is a huge market here for Hobie to make clip-in pedal arms but I bet they don't because of liability if someone rolled a kayak while clipped-in.
