This looks very like a 5.5 'OffShore' I had which was made by a guy up in the North East. I think Jono may have had an older one. Mine was 2003 and fitted with a Honda 90 it was a first class boat. I had my own ideas on what it might have been 'based' on but it had a generous V with a sizeable planing pad and was a great boat in rough seas. The build quality -especially the shower tray area- was first class in both finish and strength.
The high console offered great weather protection - appreciated when these pictures were taken in early April. Another nice feature was the seat pod split from the console by a 9" gap which both separated the battery completely from the fuel tank in the console and meant step through to sit on the seat instead of having to lift a tired leg over the seat. Nice when you're tired and/or the sea is lumpy. It also had a 3" trunk moulded on top of the deck to neatly route all cables.
Just thought I'd share my opinion in case anyone comes across one for sale and wants to know what it was like to own/use. I'd have another one in the morning.
I agree a 90 is never going to be good enough on any 6.5 especailly a solidly built one as for full of lardass divers.....
