Salty Ditty by Kevin MacLeod
Avast ye maties! All your boat are belong to us! Super chipper piratey-like 8bit tune. I mean, it could be used for non-nautical things, but the audience will probably be all like "Hey! Why is there an 8-bit pirate shanty going on here!?" Perfectly loopable for all your casual seafaring games. Or game reviews. Or actual voyages. Or voyage reviews.
