My 1989 Robalo 2660 leans to the port, while running and standing still at the dock. Had the boat surveyed before I bought it and the surveyor said there was no delamination in the hull and there was no moisture content. The water tank, stove, head, and sink are on the starboard as well as the helm (obviously). Gas tank is in the center. I don't have trim tabs but they wouldn't keep the boat straight while docked anyway. Anyone know why she's leaning?
