The sailboat really needs to be faster. I also agree about the need to not have to hold down w to sail, my poor finger.
I did a little test for the sailboat against the raft, and it seems the sailboat is no faster than the raft. In the test, I took the sailboat up to the trader first. It took 17~ minutes. I took the raft back and the time was almost the same 17~ minutes. And no, the commodities trader didn't have any tin for sale
