21LSB... For a 20' Twin Eliptical Pontoons, would 12' long alum planks be ok for support and boathouse lifting or would 16' be a better option?? See PICS All suggestions Welcome!! Thx! John (very new)

Your cross beams are 102”, or 8.5’...which is the width of the boat. Gonna be a tight fit. My Hewitt lift is sized for a 120” clear width, so I would suggest making those beams longer.

I would also go with the longer bunk boards.
