What do your engines burn per hour at cruise
speed and figure your range? I suspect you will be surprised at how few miles that will be. You can extend that by a fair amount by slowing down, or by running on one engine
for most of the time. it is a little harder on the autopilot
, but doable. I suspect that you will need large bladder tanks
to get you to your next fuel stop with a safe margin for error. I dont know if this is a new or used boat
, but I would take with a grain of salt
any range that a builder
or previous owner says. Being a bit skeptical is better than being 100 mile short of a port and out of fuel. ______Grant.
