This has been discussed several times, I use a system like
this one but have an idea for a simpler solution: I have an eyestrap on the mast, about 70 cm or so above the base, for the jibsheet jam preventer, I'll just hang a line with knots from there, with a bungee takeaway under the tramp, to pull myself aboard. Maybe step on the the dolphin striker with the knee or with a foot against the hull. Unfortunately I cannot go sailing yet, what do you think?
