As Greg has summed up above, the 805 ticks a lot of boxes for my needs. It was the right boat to buy 2 years ago and having spent a few days weighing things up, it's still the right boat for me now.
Went to see the Barracuda 9 today. Love the front deck area but there is no real gain in stern deck area. Add in an outboard instead of a full width dive platform hanging out back and what I would gain in some practically I would lose in other areas. Interior was just too much of a compromise as regards space, layout and storage. A nice boat but just not right for me at this point in time.
A huge thanks to everyone for all your contributions and helping me look at things from all angles.
I've decided to modernise my 2007 805 and the next time she's out of the water I'm going to invest in a more modern plotter/sonar.
Now that's a whole new can of worms!!
