So, the PVC cat in the other thread got me thinking a bit. I see lots of discussion about beach wheels, cat trax, Etc., but no mention of just sliding the boat around on a couple PVC tubes. I kind of sail in a bit of a vaccum (same lake, same boats, each year) but that's what we do at my local lake. Stick em under the boat and pull. On firmer sand they'll actually role with the boat. Move em a few times if you have to go far. This morning, I had to move my boat about 40 feet to back up from a rapidly rising shoreline - couldn't have taken more than a minute. Not sure if this is a commonplace practice or not - thought I'd mention it as I see a lot of folks balk at the cost of wheels, whereas a couple tubes will set you back about 15 bucks.
