If less is more...
then my kayaks certainly fit the bill.
Each is lightweight and I can carry it a block or two between the car and beach.
No launching facilities are needed.
No control lines are present. Except maybe a piece of line for tying up to a pier or to tow wandering Rhinos or conked out motor boats.
No mains, jibs, genoas, spinnakers, lower courses, fishermen, flying jibs, studdingsails, t'gallants, royals, etc. And certainly no steenkeen motor! Instead the propulsion is simply one double-ended paddle.
Maintenance procedures are simple. Roll the kayak over on the beach or pier to remove rain or lake water quickly.
Some gunkholers think their centerboard boats do well if they can quit sailing and paddle, motor, or pole into shallow water. But how many of them can handle three inches of depth!
Bridge clearance is a non-issue... air draft is about twenty inches when I bend down to paddle under a marina gangway.
And no danger at all of accidentally hoisting the bitter end of a halyard or topping lift beyond where I can reach it.
