not hard at all. mine was used. has a separate base the tower slip fits into. just made the base higher so the legs hit the roof. legs have some play before you bolt them down so you can line it all up the way you want. i also have a stick mounted at the top of the tower. its all simple ingenuity
Hi, I have the top of a large tuna tower from my 48' sportfish that would be perfect for your boat. I removed it because of height clearance issues in my area. It is actually offered with the sale of my boat but if I sell it separate first thats okay also. Its located in Bridgeport Ct. My boat is listed on ebay right now and there is one phot of the boat with the tower still installed. Its a 48' Marine Management Sportfish.
