Aluminum is not the best material for a saltwater boat. I own a 22' Alumaweld and bought her mainly because I trailer around quite a bit, up to the Straight, Coastal out of Westport or Chinook, and also doing the lower Columbia below Kalama, or back to the South Sound.

I've had issues with the way my boat was rigged at the factory, wires spiced in the bilge area, windshield wiper grounded to hull rather than back at a ground buss, and the lack of a weather resistant fuse assembly at the batteries.
A friend has a North River which appears to have nylon washers to help isolate hardware from the boat, but he has had issues with the fuel fill/vent intallation allowing water into the fuel cell.

Every boat is a trade-off. List your wants and needs. If you still decide to go aluminum, well, go with an outfit that will cater to a salty boat. :two cents:
