I like the Danforth anchor idea as I don't think the cylinder block or mushroom would hold the boat in white cap weather with the main up. I've been thinking that if I drive a stake on the shore I can have a long line attached to the wheels and for launching I could just let them float, as long as I wasn't at a ramp or similarly congested area. If there was an anchor off shore then there could be a line attached to that also. Maybe the line could be a loop between the stake on shore and anchor off shore with the wheels attached to a point in the loop. It would be like the clothes line Mom had when I was five, there was a pulley on the house and another one some fifty or seventy five feet away attached to a post or the garage. There was a rope that made the complete loop and she would hang the laundry on one side of the loop and pull it out using the other side of the loop. I always thought that was pretty neat.
