I had a very close look at these RIBs, and in the end it was between the Avon and the Pro Sport
They are a Medium V Hull design - but handle very well.
They are built in the Channel Islands - and if they can cope with the seas there they should be able to cope with most things you would want them to do.
They are very well spec'd, extremely well finished, and competitively priced. I did have a whole load of information from them - right down to how the hull was made - but I cleaned out some files off of my computer last month.
I would recommend having a closer look
