I am about to convert my lift as well from V-hull to Tritoon for a 23RSB. I want to have as low of a profile as possible due to seasonal low water. (currently my lift is high and dry due to the scheduled draw down of our lake this year...most years have plenty of water year round but it can be shallow) My Bennington Dealer suggested three 2x10s that are 16 ft long in treated lumber (MCA treated - so it'll be safe with aluminum), each running under a toon. I do not plan on covering them with carpet but may stain or water treat them. I plan to use carriage bolts through the existing aluminum I-beams, counter sinking them if possible. Does this sound reasonable? Are 16 foot long bunks required? (I see many of you use shorter bunks.) I know Team Bennington suggests that all of the toon support points be supported, but that doesn't seem possible on a 23 ft long toon. Attached is a photo of my current lift. The cradles are 9 feet apart. If I use 16 ft long bunks, I will have 3.5 ft of bunk extended in front and behind the cradles. (and 7 ft of pontoon not directly supported). Should I place the bunks spaced evenly so the same length of bunk hangs over the back and front of the cradles? Thank you in advance!
