The tiny pins that came with the mast step link from Hobie can quickly end up bending the step link and causing a mismatch as the base of the mast centers on the cup on the crossbar. I replaced the 3/16" pins with 1/4" Ball-Lok Quick-Release Pins (
West Marine link). The two pins are much longer than you would use on the side stay, for instance. I don't remember what length they were, but 2 inches comes to mind. I drilled a hole in each of the bells to run a lanyard between them, so I didn't lose the pin(s) in the sand. They're a little expensive, but they won't ruin your retirement. Besides if you wanted to save money you wouldn't have bought a boat.
