For the second year in a row I have chartered a 3-day family vacation
as a combined instructional charter and cruise, i.e. I go on vacation
with my family while a captain helps me with the boat.

Last year I did this in a 42 foot trawler; this year it is a 54 foot
Bluewater.

For the second year in a row air conditioning has been inop on the boat
and the rental school seems to think this is a typical occurrence in
the boating world and something a renter should just take in stride.

Perhaps I need to recalibrate my expectations. Or perhaps the school
does. I do not know which.

If a boat is advertised as "luxury accommodations" and is taken on a
3-day instruction/charter cruise costing several thousand dollars, is
lack of A/C an expected occurrence and non-issue?
