Be advised that learning to sail in a small keelboat may present some physical challenges. Physical actions around a sailboat are often awkward, and require the ability to move from side to side from a low seated position, to duck under the boom while moving, and to step from the dock down to the sailboat below during low tide.
Try placing two kitchen chairs facing each other and moving from one to the other quickly to get an idea of the movements. You must also be able to hoist a small main sail and pull in on jib sails.
If you are concerned about potential mobility issues interfering with your experience on the water, consider learning sailing through a program offering instruction on larger, cruising style sailboats where physical strength and agility requirements are typically less demanding than those on small boats.
That being said, learning to sail on small boats like ours is an exhilarating experience…and also a lot of fun.
