I usually keep a box of those picture hangin hooks in my box, (submergered boats can be a bear to "pickle fork" in),The first thing my 10yro son does when we show up to "the pond", is walk around and inspect everyones boat for a hook,(he operates the local boat recovery service here),he sells and installs these hooks(just a drop of ca glue), for a buck a pop,which also subscribes the customer for that days service's......the way these guys (maniacs) run at "the pond",keeps him(and me)in beer and bubble gum for the weekend.....
