HOW TO MEASURE BOWEYE TO TRANSOM
Accurate measurements are essential when choosing the right trailer for your boat. This guide explains how to measure your boat correctly, including the key bow eye to transom (BET) measurement, helping you determine the supported length needed for the perfect trailer fit.
Boat Length
When deciding on a boat trailer, you will notice that when referring to boat length it mentions the bow-eye to transom (BET) length. Boat trailers are fitted to your boat by this measurement and it is the most critical measurement when selecting the proper trailer for your boat.
When determining the bow-eye to transom (BET) length, you should never include the swim platform, bow pulpits or Euro transoms. Many boat manufacturers include the length of swim platforms and bow pulpits in the overall boat length. It is important that you make sure you get the correct bow-eye to transom (BET)/drain plug measurement otherwise it can result in an improper fit.
You will find some resources below to help identify where to measure to and from when measuring the bow-eye to transom (BET).
