Monster foam noodles sold at Walmart cost about five dollars each, size 5" diameter x 42" long and are good for rolling a small vessel like a jetski or small row boat, or small sail boat across the front yard and down a rocky embankment ramp made with 2"x8"x10' planks.
For retrieving the small vessel in the fall, get a $45-power pull with the polypropylene rope included from Tractor Supply. For relatively light moves the rope power pull seems to be easier to use than than the stronger cable pulls made by Maasdam and sold at the late great Laconia ServiStar Hardware.
........ anchors away! ....
..... plus now you have three or four foam noodles for swimming improvement and synchronized water ballet!
