Yep they can be a sundeck also
thats the way the bayliners are. they have grooves in the gunnels and notches on the engine compartments that allow the seats to convert to a sundeck.
Like what Justin said,
I only built boxes under the seats for storage. The seats came this way from Bayliner.
Bear first time I read this post. I must say you have some real skills. That bayliner you rebuilt was incredible. I am sure the person you sold it to was one lucky person. Well I guess if you ever decide to go into another field you know what you can do for sure.
