You could just type "Exit" to get out of the boat...
I thought I tried that, must have missed it. There were others like doorways without a compass direction where I had to cycle through the compass points to move. Anyway not the end of the world, especially not in a speed written game. Just a QOL addition that would be nice, particularly as in these comps you often get people who don't play a lot of parser games and clear instructions can help them out. For the record I didn't give your game 1*
