[Rhodes22-list] Trailering With/Without The Mast Crutch? - Winter Storage

[Mitch Mitchell]

I’ve been using kayak pads. You can buy ones that match the railing tube diameter. I haven’t done much trailering Yet but it seems to work.

I built a smaller crutch to bring the mast down closer to the stern rail and used webbing (2000’ roll from Amazon) to create a grid to hold a tarp and prevent pooling. So far so good. The weight of the mast is on the bow pulpit as per normal and on the improvised crutch (two 2x4 sections) sitting on the transom as does the regular crutch. The web strapping ties to the stern and side rails with web straps completing the side rails.

>> The mast was not designed to be unsupported for ~22 ft, the distance between the bow and stern pulpits. Think of the mast as a spring. Left unsupported, the mast will vibrate as the trailer goes down the road. If you add in the mast crutch, the unsupported distance is cut by ~1/2. This increases the resonant frequency of the spring outside the range that will be encountered on the road. While the mast will not fail immediately due to this over the road vibration, every cycle is adding to total fatigue cycles. The vibration on the trailer is much higher frequency vs when the mast is stepped on the water. This means the fatigue cycles add up pretty fast on the trailer. A 100 miles at expressway speed with the center of the mast unsupported probably racks up the fatigue cycle equivalent of several years of use on the water. You are definitely shortening the life of your mast if you trailer without the mast crutch supporting the center.
