The scrambler is a resort 'yak - stubby and stable. Not a lot of room, and it paddles just OK. But if you're paddling any distance at all (and you're not huge in the hips) I recommend the Scupper Pro TW.
It'll hold all your dive stuff, and it's a touring rig (long and narrow) - so it paddles like a dream. The Fish & Dive is another yak targeted at divers. But I hate them - they're double wide, making them very stable - but they paddle like a barge towing another barge. Load them up and you're just working too hard to get to where you want to go. Unload it and just go and play some weekend, and you'll ask yourself why you're hauling around all that extra plastic. No thanks.
My boat needs to do more than serve as a dive boat - I tour with my wife when we're not diving (by touring, I mean paddle around...not like from So Cal to Anchorage stuff...) I fish from it, etc. I'm confident that you'll do more than dive once you get it, and paddling is what you'll be doing most in any yak - I just don't understand why you'd choose something that doesn't paddle as good as the SP.
