Thanks to everybody who gave information and experiences.
I went to the boat show on Saturday afternoon to have a scout around and see some of the boats in the flesh. I have to say I wasn't as impressed as I expected by some of the airfloor models, given that this will be my only boat, I know some of you have one as a second boat alongside your RIB's. The other thing that I found interested - and I appreciate the guys on the stands had been there for 7 days - was how uninterested most of them were in trying to help/sell a boat.
I'd just been to see friends on one of the dinghy stands, and stumbled upon the Barrus stand and a very helpful chap called Peter from Blue Water Marine in Salcombe, it must have been fate as that is where I want to use the boat.
I was very impressed with the additional strength and build quality of the HD series of boats, even taking into account that they will be much heavier with the Ali floor. I managed to get a 380XSHD with a 20hp 2 carb Yamaha for only £500 more than Tohatsu wanted for their boat (airfloor) and engine package. Really chuffed and looking forward to picking the boat up in a couple of weeks time. Peter ended up selling 2 boats as my friend bought one too
Oh and I will be having launching wheels and an electric pump!!
Will post pictures when I get the boat in October.
