I'm about to start a campaign which will have the PCs on boats much of the time, and I'm trying to figure out how to handle boat-related skills. Back in the 3.x days I just used Profession (sailor), but I'd rather not add a whole new skill (although one of my players made a convincing case that Seamanship was a reasonable analogue to Dungeoneering). The default option would just use whatever skill is closest to the check at hand, but I would like some way to represent a character as a skilled sailor. Another suggestion was to invent a Seamanship feat that applied to ship-related checks (eg, +3 to Nature checks to navigate, +3 to Athletics checks to climb rigging, etc.). Thoughts? Has anyone handled this yet?
