You seem to be saying: Assuming I need to generally run my engine (as a generator) for charging my batteries for 4 hours (in my case), when cruising for 4 hours or less, 50% of my usage is for propulsion, 50% is for domestic. Anything over 4 hours, 100% is for propulsion. Is that your assumption? I wonder if engine hours in locks could also be considered as 100% non-propulsion? Thus if I record how many locks I cruise in a day, and divide by 3 (since a lock is generally considered to take the same time as a mile) I can subtract that (number of hours)/2 from the propulsion total. Can you point us to the HMRC, or any other, website that explains what is going to be allowable under each heading? WBW John
