@6balls personally, I don't think there is a big difference with either a vertical or cantilever as well. Now our HOA prefers the cantilever. We will be the only boat on our dock, 15 slips, that have a lift. Even though we have prior approval for a lift, we're just trying to make sure no one is upset after we put it in. The one other consideration with a vertical is the outside width of it. We have 10' to work with. I see some are 108", but I'm not sure if that is outside or inside width. I haven't seen as detailed of a drawing on the verticals as a cantilever.
I'm finishing up with document that will be sent to the HOA on boat lifts so they will include that in the bylaws. I'm going to include both a vertical and a hydraulic in it and hope for the best.
