I wouldn't be concerned about the number of hours of motoring time in calm conditions. I would be very concerned about the number of hours of motoring time in really rough conditions when you have to bash straight to windward to get to safety
I carried enough fuel
on Exit Only to motor
for 1400 miles using the starboard engine
for twelve hours and the port engine
for twelve hours, alternating the engines as needed to get the job done.
I cannot tell you the number of times I turned the engines on to get into port before dark, to make it to safe harbor before the front came through, to get out of harms way.
I wouldn't sail in a yacht with a limited motoring capability near the coast or offshore
. You never know what is going to happen, and the ability to motor
indefinitely can mean the difference between life and death, between saving the yacht and losing the yacht.
Of course, Joshua Slocum and Harry Pidgeon sailed around the world without engines, and it worked for them. But when I go to sea, I want to push the odds in my favor.
A no compromise engine with plenty of fuel
gives you a decisive advantage in your battle with a sometimes wily sea. Boats get into trouble all the time, and more boats are lost
close to shore than offshore
. Coastal cruising is chock-a-block with hazards. It's when I am close to shore that I am in the "Danger Zone". I would rather sail offshore with a marginal engine/motoring capacity than sail close to shore with limited range under power.
