Hmm. Have you looked at Blood and Plunder? The era is right, but most are "action" poses - crew preparing to fight. They have plastic "sailor" sprues coming out that might better fit what you need, but those aren't due out until the fall of this year. Here's a pic of that sprue:

BnP figures run a little tall, too. Closer to 30-32mm (not too bad, but I notice it).
Have you looked at the Frostgrave Ghost Archipelago Crewmen? They're a little smaller (more like 28mm), and a few more open hands - but again, lots of cutlasses, crossbows, and sundry weapons.
Sailors doing sailor stuff - that's a harder find indeed!
