The additives offer no benefit if you are routinely burning through gas, adding fresh gas to the tank, and don't have a way for water to get into the tank.
I only use additives in fuel that's going to be stored for a few months or more. My boat only gets additive (Stabil Marine) when I fill for the last time of the season, just prior to Winterization. I buy at least 95% of my boat gas at automotive pumps (this no additives) too, because my boat is typically kept on the trailer when not in use. I've been doing this for at least 15 years without a single fuel-related issue.
