Not a sales pitch. I used the Anchor Buddy and my friend used the West
Marine model and, like me, is happy with the results.

Worked great. Kept my boat off the rocks and kept it near shore. Allowed
me to pull it to shore to let guests on and off as desired. And released
back to safe distance off the rocky shore. Use the float trick that comes
with the instructions and it's slick as downtown.

A good lake tool for keeping the boat off an unfriendly shore. Not
necessary for hull friendly shores. And not recommended (by me for
unprotected or rough conditions).
