I certainly see more black smoke coming
out of the exhausts of commercial boats than yachts.

Commercial boats get paid for WORKING, so maintenance goes undone until you
can't go WORKING any more. (An example is Charleston shrimp boats go
uncaulked until they're leaking so bad the pumps can't keep the water below
the intakes to go shrimping, their prime reason for being.)

Yachts get maintenance, most well before they actually need maintenance
because the owner has money and nothing to do with it. Ain't it grand?

Also, a fisherman headed out to be number one isn't interested in "sweet
spot cruising" to the fishing...(c;

Reasons for all the black soot shooting out the dry stacks welded up by
Uncle Henri are fairly obvious...(c;
