Hello MC Captain
I recently faced the same dilemma. I ended up buying a Hewitt 10,000 pound lift. I have a 2017 ri57 and loaded on the trailer with about 800 pounds of lead it’s about 9700 pounds so I assume The boat is close to 8000 which leaves no room for any extra weight on the lift. To be safe I would always want to size a Lift to be hold about 20% more than the weight it’s Carrying. I also assume that there might be one or two people in it when lifting the boat also which replace extra weight I’ve never owned one before so I’m not sure if this is the case but it makes sense to me that would be easier to line up that way.
