Marina's Store is right around the corner from where I am moving to this week. Perfect. But ya, a power washer can do alot of damage, I prefer to have just a hose and soapy sponge.
Jesse, I would start a bikini wash, but would hire young hotties to wear the uniform, lol. I was actually thinking about that a few months ago....but more of an automated place where you spray off your own cart, with a brush or sponge and just have a coin machine to accept the monies. It could be making it's own living 24/7 with little or no real work load on the owner. Hire a night time watchman and you are set. It saves on manpower and sunblock, lol.
