Bench or Jockey
Ask yourself the question, what are you going to use your rib for ?
You can see shots of my rib all over the forum which no doubt raise comment that she's a big leisure cruiser. She is, however, I've been out there with the best of them in the worst of it and find the bench seat fantastic. Why ? Well, contary to some opinions one can sit and helm in any conditions, however, I do appreciate that some bench seat setups are perhaps not configured as well as mine. Next, you can also helm standing up and as you'll see from my RIB she has a very handy grab rail. Further even in the rough stuff with a well padded seat and backrest there is no jarring.
The best advantage of the bench is when one is just cruising with the weather we (I) ideally like to cruise in. Sunshine, slight swell, shorts, friends and a picnic. When you pull up in the bay there's nothing better than sitting on the bench with your feet up whilst others straddle their jockeys with no where to lean back to catch the rays.
Again, ask yourself the question, what do you want from your rib ?
Buy it & Use it, then sell it and buy something bigger
