Boat Size Calculator

How to find the right size boat cover.

1. Measure the length and width of you boat over the highest points (seats / windscreen / centre console etc…) as per the diagrams (dimensions L and W). Take the measurement from where you would like the cover to fit over the sides and end of your boat (typically just under the rubbing strake).

Please note that our covers are not designed to go over the top of ‘A’ frames but tuck around the sides.

2. Enter the length and width in centimetres into the size calculator and click the ‘calculate’ button, the calculator will tell you which size of Ducksback boat cover you require.


The size 7 cover is specifically for 7.5 – 8.5 metre RIBs.
