Craziest lift bags

[raftingtigger]

...raise the engine first then the boat. ...

The engine was never underwater. The boat sank because it filled with snow over the winter (the tarp/barrels that keep it from sinking got displaced). The engine was in storage.

"You could raise the Titanic with one gallon plastic milk containers and string if you had enough of them and places to attach them." Yup, your 'rope' and attach points only have to be as strong as the amount of each lift bag individually.

Well, in March I started with this

7 bait barrels and a short tow into the boat ramp I had this

A few hours latter and with a pump I had this

The fun part was the water temp of 34F and a 2.5 hour dive to rig the barrels.

Finally got the pictures from camp. First is about 1/2 way, second is 3/4+ raised, and the last is the end result. Enjoy - I sure did.

I love it.
As the say, where there is a will there is a way.

Cheers

Me and my friend lifted a fire-gutted boat from 70ft with 15 partially air-filled oil-drums last week. We sank the drums, tied them to various parts of the boat (anywhere we thought would hold) and then filled with a scuba tank and octopus hose without the reg- ie. feathering the tank open and closed to fill.

We used two 12L Steel tanks. Starting at 200 bar both tanks got to around 70 bar.
Thus 2x 12L x 130bar at 3ata would be about 1000L of air to start the lift.

The strongest part of the structure was the engine block so we had 8 drums attached to that part alone. I was bricking myself if the wood underneath was to give way while we were filling, but I guess Murphy was busy elsewhere that day.
