I think there is a significant risk of vessel depreciation if red diesel gets binned. I sold out of the motor boat a year ago because I didn't want to stand in for a £30k loss. I've heard that the mobo market is soft at present; part of which is due to folks standing back and watching what happens. With diesel prices having gone up significantly anyway the increase due to binning red diesel will be less of a shock when/if it happens. But I see what you mean about not going out very often - I worked out that my previoius mobo (Targa 39) would now be costing £1.60/mile - which is ok around the solent but a cruise over to Brittany (say 400 miles = £650) gets a bit rich.
