to the layout, we have that. Think how far back/forward you want the bench. We got ours near to the jockeys so they could reach for the grab handles on the back of the jockeys and we got a reversible backrest so you can sit facing backwards out the wind or watch skiers.
Problem is if people are sat on the bench facing forward you can't get across the boat between them and the jockey backs. The space behind the bench is wasted unless we reverse the backrest, so if yours is fixed I'd move it a bit further back in boat to utilise the deck space between the two. Just a thought. Ours is 6.3 humber op.
I like tonyt 's ribquest colours if you like black, haves a look. Our boat is yellow and White, yellow tubes or patched show dirt/stains!!unless you live in a Marina, ours is moored.
Going to be nice!!
