Love your handy work Slack! Was talking to a fellow supper while waiting for our boards to be off loaded, I was struck with envy when he started assembling a rather fancy board caddy. He rode off with gear whilst I limped off with surfboard, sup and paddle. I had to come back for rods and bike.
I did catch up with him a couple of days and his fins had a new foil, the wind had caught hit big Sb Drive and flipped the trailer whilst riding down a hill!
Im thinking about strapping an axle arrangement to the tail of my big board to tow it, using the board as the spine.
