Broker's Comments

Here looks a really great example of these much admired boats!

She comes with a lovely, great cockpit with plenty of room and a seat that converts to a double berth - access to both engines is fantastic here too. The whole lot is covered by a large cockpit tent that, whilst it needs a valet, looks like it has plenty of life left in it.

She has a comfortable and well-equipped helm and down below a cosy, yet very practical interior, with a galley unit and heads to keep you comfortable on those overnight stays.

All in all, this boat, whilst she seems to have a few minor jobs to do, looks like a rock solid and very capable vessel that needs to be taken away and used.
