So our lake is way down and I currently have dry ground underneath my boat which is in a lift. Want to take advantage of that by replacing my lift bunks. I have a fixed wooden dock with 6x6 posts. My thought is to bolt up some joists underneath the boat (19’ across) and lower the lift so that the boat rests on the joist while I work on the lift runners. Thinking that a 2x8 single joist for the front and then a double joist in the back would be enough to support the boat. Please tell me if you think this could work or will my wife find me under the boat buried in the mud…..ha. Thanks.
