We generally list items as "per person" or "per boat". Trying to make sure those on a more limited budget are aware of what is covered by the "Kitty".
We generally do not include meals ashore, but note the cost of entrees at the restaurants we are considering.

Items included in kitty include meats from US(250), Riteway($500), Alcohol($250) , fuel($350), ice($80), (Water not needed as Sea Tiger has watermaker), trash($20), taxi (STT and Roadtown)(40 per person), rental car (1 day Anegada $85), fuel ($350), Dock Hand tips($40), Mooring fees ($210).

Specifically listed as "Not included" in above are shore meals, shore drinks, Ferry fees, 3 meals ashore (Arrival night, and 2 other islands, including 1 "lobster dinner".

I have all listed in 2 columns of excel but could not attach. Obviously, anything not covered by kitty reduces the kitty expenses and shifts to per person. Ferry often paid by credit cards and thus left out of kitty. Also shore meals/drinks vary widely by individuals and thus felt to be best requesting separate checks.
