Simply measure the boat. You can either measure side to side or back to front. Use a long tape
measure to help with this process. For side to side, measure from the perimeter strap on one side up
over the highest point of the boat to the perimeter strap on the other side.

Then, add about a foot on each side to the total to account for tucking and fusing on each side. You can also measure from the back to the front of the boat, starting at the motor and measuring to the front of the boat, and adding a foot to account for tucking and fusing.

Be sure to measure at the longest part of the boat as well. This method works well for smaller boats but may not be possible for all projects.

                             the rub rail                                     Above the      
                                      &                             =               rub rail
                      the highest point                              measurement
                            on the boat

Most traditional boats have a rub rail around the outer edge of the boat. The above the rub rail
measurement is the distance between the rub rail and the highest point on the boat where the
shrink wrap is expected to cover.

So, from the same spot as where you’ll be taking your below the rub rail measurement, measure from the rub rail to the center of the highest point on the boat.

Next, figure out the below the rub rail measurement. This measurement is based on your preference
of how far down below the rub rail that you would like your shrink wrap to fully cover.

                          How far below                                               Below the 
                             the rub rail                         =                         rub rail 
                        the shrink wrap                                          measurement
                              will cover

Cover the exposed area of the boat, which means everything above the waterline up to the rub rail.
Be sure to take this measurement in the same place along the both with which you took the above
the rub rail measurement.

Last, figure out your tucking and fusing measurement. This accounts for the extra material that will
be used to tuck the shrink wrap edges under the strap and heat weld the shrink back to itself. Add
6”-1’ per side.

                        Extra material used
                        to tuck shrink wrap                   =               Tucking and fusing
                              edges under                     
                             (6” per side)

Add the above the rub rail measurement, the below the rub rail measurement, and the tucking and
fusing measurement and multiply this amount by 2 to get your desired length of shrink wrap.

Our 7 mil shrink wrap is the most commonly used shrink wrap for recreational and personal boat
protection. It’s perfect for wrapping all size boats. Ideal for wrapping objects that stay in one place.
