Since I brought Flirt to my Father’s, her mast has been resting on the snow tyres and rims to my Land Rover. While it worked well to keep the mast off of the ground, it looked fairly trashy and was hard to mow around.
Thirty some odd years ago when my Parents had their Grampian 23, my Father made up some plywood “hooks” that were bolted onto the cedar fence that surrounded our backyard. It worked very well at both holding up that mast and protecting it from being bumped around and from our dogs (My parents raised Siberian huskys at the time)
The fence around my Father’s place is chain-link (and in not the best of shape) so constructing something similar to what he did was out of the question. Instead I took 3 5 gallon buckets from work (they ship fresh fruits and veggies to the restaurants in them and then toss them in the trash), built up some 2x4s with plywood hooks to fit in them, filled each with 40 pounds of cement, and painted them green.
I now how three very heavy but easily moved supports that can hold my mast and boom (Which is still lashed to the trailer) up out of the grass, safe and sound. I think they cost me all of $20 total to construct. (half of that was paint)
