Oh, since we're sharing, my first seed was: duzpmJcTP8

Turned out to have two Maypoles, a nearby Trader, and every boss on the first (quite large) island (some narrow channel swimming required).

My favourite feature of it, though, is the isolated 200 metre x 40 metre island that is 95% Plain, and 5% Dark Forest, where careful placement of torches prevents all spawning and allows growth of flax and barley without risk of attack. (That did require some sailing.)
