Dr Pain, That is a hard question as I tell people when they ask me how much to do their boat. I first have to look at the job at hand and then find out the customers expectations. I also have to look at the size and type of vessel. Flying bridge, tune tower, outriggers, teak, stainless, aluminum. I have a wash price per ft that depends on the length and type of vessel, I have polishing pricing, compounding pricing for both light and heavy oxidation and a sanding price all based on length and type of boat. A flats boat is quick and 43ft Maverick is a lot more per ft. Also the gulf coast prices tend to be more the the Atlantic Prices as I have seen. If someone calls me and asks what a wash cost I tell them $5.00 for the wash from the rub rail up on a 45 and below. I tell them is just a quick swing and "If They" want me to look at the boat and go over what they want done the price may go down depending on their expectations. Pricing is the hardest part to this all, you don't want to be the cheap guy but also you need to cover cost on product, time and distance. Call around to detailers in your area and see what pricing is going for, I do wash boats for $2 a ft if I am hitting them on a weekly to biweekly bases. This is a wash, rinse, wipe and go. 25 footer in less then an hour and hopefully I have 2 or 3 in the marina to do on that trip, then off to the next stop. Scheduling is the bear, everyone wants a clean boat on the weekend. Good luck.
