1. Measure the Overall Fabric Length
Using a tape measure, take the following measurements on your boat making sure you measure from 15-30cm below the point of the bow of the boat (assume this is where the hem of the cover will be) all the way back to 15-30cm below the stern, ensuring the tape measure goes over the windscreen.
If you have a Bimini, ensure this is folded down and resting on the gunwales and that when you measure from bow to stern the tape measure goes over the folded-down Bimini.
If you have a permanent Bimini or other similar structure mounted on your boat, this style of cover will not be suitable for your boat. Please look at the Jumbo-style semi-custom covers.
2. Measure the Overall Fabric Width
Using a tape measure, take a measurement 15-30cm below the widest part of your boat on the Port side gunnel and across to 15-30cm below the opposite Starboard gunnel ensuring that the measurement goes over the highest part of the boat, ie, windscreen.
Once you have these 2 overall measurements refer to the below table showing the overall cover dimensions for each size of cover offered and match up to arrive at the best fit for your boat.
