If you look at the map there is a lot of contiguous water in the game and it would be nice to take your boat, perhaps pay the cart guy to haul it to another body of water, and row it to close to your next destination. Then you could quest and bring your loot back to the boat to store and to haul when you are finished with the area.
I dunno perhaps a Dwemer outboard you have to feed soul gems to might be cool as well.
