There's a reason why the world's maritime industry stopped using sailboat fuel to power warships and cargo vessels.
Can you guess the reason why?
The doldrums?
Speed. I’ve pointed this out in my sailboat group. I’m from Savannah, Ga and one day at the beach, I saw a boat called the Philadelphia Express leaving out. I was tracking it on an AIS app and noted that 4 days later, it was in Lisbon Portugal. 4 days! Great if you need something there fast.
But, like I said, our boat (a Tashiba 36) is slow, no matter how we propel it! But, she can sail the world given time.
