Bought a used 03 BT Cruiser (21 foot). The PO did something to the back ladder and it is seriously messed up. Kind of looks like he hit something horizontal towards the top and the bottom. Who know...
Brand? Not much info from me. I needed some parts and found exact match at marine store. I would suggest doing some close measuring of current ladder. Close look at the mounts to the rig. You maybe able to find make on existing.
