Here's a few that I like a flavor-wise but are all also strong mechanically (all have full BAB, all good saves, decent skills, and some stat synergy):
Magus/Swashbuckler is good- at low levels inspired blade is a good option for stat synergy; eldritch scion is a bad archetype at low levels but after 8th an eldritch scion/vanilla swashbuckler is probably better than an inspired blade/other magus...
Daring Champion cavalier/Bard has been mentioned but I'll repeat it... I like the arcane duelist archetype for this but the archaeologist has some potential too. Mechanically, one of the dervish archetypes is probably best but I don't really like their flavor for pirates.
Divine Tracker ranger/Druid has a lot of synergy, can get an aquatic/amphibious companion, has water and weather control abilities, gets blessings for flavor, can wild shape into sea creatures... I haven't looked much at them but the tempest or aquatic Druid archetypes might fit well in this style game.
Eldritch Guardian fighter/Buccaneer, Savage Skald bard requires a little explanation... Take a parrot for your familiar and give it the sage archetype, dump your Int- now you're a bard that sucks at knowledges but your talking parrot has them covered, lol; you're still a hard fighting salty dog who always has a sea chanty at the ready when it comes to blows.
Mutation Warrior fighter/Steelhound inquisitor doesn't gain bombs but is otherwise a gunslinging alchemist (on steroids)- could be fun as the ship's cook/brewmaster (or the quartermaster).
Gunslinger/Inquisitor is all about proper god/philosophy selection... Mechanically it's a bit of a powerhouse (judgement and bane on your guns can be pretty sick), but you need to worship the right god to get the right flavor- either one strongly in favor of slavery or one vehemently against it will make him the token zealot who truly is concerned with that conflict above loot or crew or anything else. (Gunslinger/Warpriest could probably do this well too.)
Stygian Slayer slayer/Arcanist (or Wizard) would make for a mysterious/shadowy enemy who can track or scry, use stealth or invisibility, and eventually can dimension door (or teleport) in and out of their ship as he pleases.
