Keep your sailboat. You go just as fast. You are used to the boat, you know all the systems. If you have trouble hoisting the sails, get an 18v Milwaulkee drill with a 1" winch handle sized bit and up they go. Unless your 70 yrs suffers from dimentia, sail is still a great way to go, but don't cause a complete halt to your boating by taking on a new challenge that you are not up for.
I dunno... systems is systems. Sailboats have 'em, powerboats have 'em. I'd imagine any sailboat would have pretty much the same systems as a powerboat of equal appointments and offering similar features. Engine, plumbing, whatever... and fixing something on a trawler shouldn't be much different that fixing the same thing on a sailboat. (Assuming access issues don't hose up the plan.)
Your comment seems useful as counterpoint, though, especially if OP already has a sailboat. (Not clear.)
OTOH, turn key, point boat... (usually)... can really simplify the "getting there from here" part of boating... even compared to electric winches... and without regard to the various service, maintenance, and upkeep issues inherent to most all boats.
FWIW, learning new systems might also be interesting and useful mental exercise for its own sake... contributing to preserving/maintaining mental agility and all that...
