A Columbia 24 underwater only weighs 3500 pounds. You can put two small boats (17 foot up to about 25 foot will work) over her separated by 4 by 4 wood beams lying on the bow and stern of the two boats. Put slings under the Columbia and lift with a come-along. You will only need to support 1750 pounds on each boat with only 857 pounds on each of the four lifting points. Its safe, controllable and cheap to get everything together. We have done this in places where we couldn’t get the barge and crane and when we didn’t have air bags handy.
Using old drums is difficult to setup and I wouldn’t do it that way. The company in Providence RI that makes the air bags will rent them out. I don’t have the name or number handy but an internet search will find them. Its easer to rig a bag then it is to rig an oil drum.
All the best,
