Option 1:
Pay the marina. (every year)
Pull the $1000 depth finder, the ignition key, the envelope with the "papers" and store in the trunk of the car.
Put the cover on, all the time hanging over the sides struggling with the snaps with arthritic fingers.
Worry every time it rains real hard or the wind blows.
Just before going fishing, do the reverse and figure out where to store all the wet canvas.
In the Fall, pay someone to clean the hull, shine the brightwork, etc.
Option 2:
Pay the boat dealer to sell you a launching trailer. (one time cost)
Easy peasy at the launch ramp, solo or with the family.
Put the boat in the garage and casually throw the cover over her to keep her clean (also easy peasy)
Casually wipe her down and keep her clean and looking like new as time permits.
Charge the battery any time you want, like just before you go back out.
In the Fall, do maintenance on the hull.....err, never mind, doesn't need any.
Been there, done that. The "work" required to keep the boat at the dock greatly exceeds the time and effort to launch and retrieve.
