Personaly I think speed is relative.. My boat did not come with a speedometer but id guess it goes 70 something.. We were out the other day heading across the broads.. Typical situation where the 4 big cruisers all headed across my bow from the west all failed to stand down.. upon looking to my stern I realized another 35+ footer was full bore up my stern.. IMHO I had no choice but to avoid this typical situation with liberal use of the throttle.. It all worked out well and I remembered to give them all the universal signal..
