RIBase
armstrong brackets/ floation boxes

I notice that the americans seem to have a thing for placing armstrong brackets/floatation boxes at the stern of their ribs. Is there a reason it does not seem to be done on this side of the pond? Nice boat by the way.

Because it would look funny at the front?

Actually, no idea why they're popular here and not there. My 18' RIB has the motor pushed back by something like 2.5'. You actually gain quite a bit of deck space, as the area normally taken up by the motor tilting up is free. The pod itself makes a decent swim step for divers coming back on board.

I'm sure pushing the motor back has an effect on handling, but I haven't quite worked out what it is, other than making a smaller hull act as a longer one (assuming a wetted box - it would theoretically be possible to push the motor back with no additional wetted surface, though I've never seen that.)
A longer hull for a given wetted beam should be a bit faster for a given input power (I think.)

Have you run the boat and seen 60mph, or are you guessing on top end? Im building one and using a single and trying to see how big i need to go? was thinking yamaha 350hp.
