Welcome to Cruisers & Sailors!
If your interest is primarily trawlers, you might check out Trawler
I am identity-confused; a lifelong sailor that recently bought a trawler. So I play on both sites...
With the present health
realities, I suspect few owners with boats for sale
will want to rent. That would seem to make showing the boat
to buyers much more difficult.
An alternative is for you to buy a sailboat or trawler in need or repair and use your professed skills to increase its value. Even better if the boat is the one you want to loop.
