The boys are right - I have exactly the combination you're looking at. The 30 is a tad underpowered for the 4m Searider and doesn't have power trim and tilt, but is perfectly adequate for your first RIB. Just don't expect to start pulling skiers with it, although it will pull a ringo as long as the occupant is not built to Herr Rat's proportions
You'll probably want to upgrade the package at some stage in the future anyway, so little point in splashing out too much cash until you're more experienced and have a better idea about what you want out of a RIB and what sort of conditions you want to go out in. If you want to discuss further give me a ring on 07768 153 386.
