the Chesapeake Bay

possibility of a trip to Bermuda
Whadda u tink? 30, 40, 50?

Yawl with a 4 cyl 38hp diesel.
You can sail. You can motor
everything. I've done the Delmarva trip 4 times now (some discussion on my blog, below) and I found that the ability to motor
as much as 100 miles really cuts down on the need for marina hopping, should the wind
die. The longest run between fuel
stops can be Cape Charles to Lewis to Cape May, depending on draft
, which is over 150 miles. So, perhaps 30 gallons is a good minimum. More likely, you can fuel
in Ocean City or Chincoteague if the wind
The counter argument, you mentioned; your fuel is going to get very old, which can bring its own pain. You cannot leave the tank 1/2 full, unless you really want polymerization/oxidation sludge and biological contamination issues.
Clearly, the best answer is more tankage and more trips!
PS. I am looking at uping the tankage on my new boat - Bermuda is calling... loudly!
