I had the opportunity to help a nice family get their very big jet boat off of a gravel bar today. I did not ask how it happened because I did not care, it just does sometimes. I was talking with my boating buddy on the way home about the experience and we made some observations that I will try and list out here. They may seem obvious, but only if you have been out there pushing a big inboard around for any length of time.
1) Let the water (if there is any) do some work for you. Push or pull down stream.
2) If you are turning the boat, push/pull as close as you can to the bow. You have the most leverage and it is lighter. Usually the ass of the boat is what is buried and you will be pivoting off of that. The lever arm may be 10 or more feet long with a pointy nosed boat.
3) lifting the back of the boat is silly unless you have a big mechanical device. The engine and jet unit weigh over 1000 pounds, let alone the hull. If there are 4 people they may have to try and lift 200 pounds each or more to lift the boat up a little. Not likely for long.
4) Get the nose pointed down stream. Boats move better that way.
5) Get as much weight out of the boat as you can.
5) This activity is especially bad on any herniation of an intervertebral disc.
6) Bring enough gear in case man power alone does not work. This includes a shovel, LOTS of rope, and a way to make a mechanical advantage for pulling. Maybe a sea sock or parachute. Has anybody practiced with this gear?
7) Standing in the water is cold around here. Have wading gear with you even if you don't plan to get in the water.
8) Don't be afraid to ask for help, but maybe reserve hitting the help button on the SPOT unit for a little while.
9) Don't quit, just keep working at it.
10) For heavens sake, get a stomp grate for your inboard boat. There should be a law against selling them without.
