Woodsy,
Yes, it's very clear to me also!
But I can't tell you how many times I've been in that channel and had to try to encourage people to move along. To me, this means that most people are trying hard to comply with the 'no wake zones', but almost to the point of being dangerous to others!
Small boats and jet skis may not feel it as bad as larger boats. But if you have a 38 foot boat (12.5 ft beam) that has over 16,000 lbs of weight (think: inertia), you sure need to maintain headway!
I've often thought I need a bull horn instead of a horn to warn others, but that may not help much either!
