I e-mailed BW last night and recieved a reply at 11.30Hrs this morning.
Thank you for your email
Your friend is incorrect, the numbers on the registration do not indicate the year of registration.
The registration number is just a straight number sequence and the computer system automatically assigns the next number in the sequence to each new boat
Other news, we rode our bikes today to the nearest village, so what I here you say, well it is a long time since I rode a bike, at the moment nothing hurts.
