We are far from experts. But the first time we chartered a Moorings 41.3
monohull so our experience might be a relevant:
1) We had problems with
power management and
lost food because of thawing. You need to listen attentively to the charter briefing and heed any comments about how long the
engine needs to run to charge
batteries and cool the
refrigerator. If they say to run engine for two hours, do so after you have finished
cooking and opening the cool box so as to keep the food fresh.
2) We very much like to bring frozen food. We freeze the soft side cooler and freeze as much as possible of the food. We haven't used dry ice, but do use icepacks. Then check it in on the airline. Last time we took 6 x steaks, 2 x Costco large cheese plate, 1 box wine (not in the cooler), bacon, lunch meat, lox for bagels (someone else brings the bagels for the first breakfast) and a large chilli. We also bring coffee, tea, decaf tea, and fixing for Smores (hersheys+gram crackers+marshmallows).
3) We have been to the BVI twice and were not asked to pay tax on the food either time.
4) We had moorings supply the rest of the food. No problem with that, but next time we will try to do everything ourselves.
Have fun
