How to Measure Your Inflatable Boat

A Maximum of 72" Tube Center to Center

B Maximum of 12'-6" Distance fro Bow Tip to Transom Support

Size Limit on Inflatable Boats - In order to support the Transom, the boat should be no more than 12'-6" from the Bow Tip of the boat to the Rear Transom. Dimension "B"

It is best to physically measure the boat, however you can compute it approximately by:
EXAMPLE : Boat is 15' Overall length - the inside distance from the inside front to the transom is listed as 10'-0" - Add the Tube Diameter 22" = 11'-10". The center bunks will then position under the transom for support. In some instances you may be able to pull the Boats Bow flush against the Dolly's handle to gain extra distance. Maximum Weight Capacity is 700 Lbs, and large boats may need multiple persons to move the dolly.
