I cleaned a 35foot SeaRay yesterday.I clean boats every year, and yiou would think by now I would know enough to charge more. Water-damaged including woodwork. I cleaned wall panels and the bunk-beds in the side cabin. Mold mostly on outside walls, ceiling in good shape with no leakage evidence. Very detailed working environment, using SS and three individual PMF upholstery tools,switching back-and-forth as needed. I left the ceiling for another trip, as there was no forward berth mattress to utilize. Started out at 8am and finished at 3pm, all for $400.00. Truck ran from 7-3:30, so with fuel costs included, I was doing the client a favour as such. My next scheduled, is a 390 SeaRay, and I will be quoting it at twice the price.
