Hi Simon, Don't be worried mate there will be Plenty of good advice on the day, 12v is OK, you will be in a team of
three. One tug takes a single tow round the course the other two tugs take the other tow round, then when you get back to the docking area all three tugs go round with the third tow and that is your course compleat.
Hope this helps you.
Cheers
John POLL
