The Oasis (2011 and newer) is probably the most versatile boat in Hobie's fleet of kayaks. It has stand up stability, holds a ton (almost), solos at over 5 MPH cruising from the front seat and is more fun to use solo than tandem (IMO). Mine weights 86 lb. (bare) and I carry it in the bed of my small truck with a bed extender for easy loading.
The secret to solo performance is ballast. The boat runs fastest from the front seat with about 25# ballast in the extreme rear. From the back seat you go about 1/4 MPH slower with about 55# in the nose. Of course that would vary depending on your weight and gear. The objective is to have it ride level. Also you want your unused drivewell plugged or sealed (I use packing tape with excellent results).
For fishing, the back seat has two rod holders,gives you access to the cargo well and the front cockpit, and has lots of width (best for standing). The front cockpit is longer though and you can mount rod holders on the rails, but access to the other parts of the boat would be severely restricted. With the dual steering controls, you can move back and forth, getting the best of both!
The Oasis handles wind and chop quite well. I think it comes with the large sailing rudder, and I would recommend Turbofins. I use the standard Hobie cart (least expensive) and it handles the boat loaded with gear with ease (not great in soft sand though).
