Transporters choose the truck, trailer, permits and route from your boat's dimensions. A difference of a few inches in width or height can decide whether a permit or escort is needed, so measure carefully, and say so if you aren't sure.
Length overall (LOA)
Measure from the very front of the bow (including any bow pulpit or anchor roller) to the very back (including the swim platform and outboard motor or engine bracket). This is often longer than the length in the boat's name or brochure.
Beam (width)
Measure across the widest point of the boat, including rub rails and anything that sticks out. Why it matters: the standard maximum width on U.S. highways is 102 inches (8 ft 6 in). Wider loads need oversize permits, and much wider loads need escort vehicles.
Height
If the boat is on a trailer, measure from the ground to the highest fixed point, such as the windshield, T-top, tower, arch or flybridge. If it's not on a trailer, measure from the bottom of the keel to the highest point, and the transporter will add the height of their trailer. Why it matters: many bridges and overpasses limit loads to around 13 ft 6 in, so tall boats may need parts removed or special routes.
Weight
Use the dry weight from the manufacturer's specifications, then add engines (if not included), fuel, water and gear. An approximate figure is fine. Transporters use it to choose equipment.
Sailboat extras
Also note draft, keel type and mast length. See sailboat transport.
