This maneuver is to prevent propeller cavitation and the resulting loss of thrust. Without thrust your boat can easily hook and spin. One of Tres' pearls. Not that he just advocates jerking the wheel.

Ive taken the course twice. It had that much value to me and the safety of my passengers to learn to operate correctly. It's all fluid motion and hands are not at 9&3. Hold... And release. Way more to a proper turn as I learned it but why would Tres or anyone else give it away. It's our investment and learning hands on is the only way to "get it".

Take the course, it's worth it hands down.

Exactly what I attempted to point out above......I hear people all the time say how expensive it is but will buy 3 sets of props in a year. As you mention, what is the price of you or your passengers life worth?

This thread is loading up with misinformation. Mr. Martin is clearly talking about stepped bottom vee's and cats. Straight bottom vee's are a different animal. Also, there is a big difference between prop ventilation and prop cavitation. Prop ventilation occurs when the propeller approaches the surface of the water, and is the subject of the article. If sufficient air is entrained into the flow of water the prop can no longer produce thrust and ventilation occurs.

Yes, essentially when the boat is turning the hull is displacing water and therefore the propellor does not have clean water to grab. The course teaches you to keep the propellor in clean water so that if something were to happen, your propellor will always have a clean water source to correct. I would suggest everyone to take this course and not just go out there and trying this based off an article. It's harder to perfect in execution. Brad was a great teacher!

I did it in his class but in real world boating life, I have used it only a few times.

Mine is a flat bottom Vee and he not only showed me this move in my boat, he wanted to beat it into my head that this is how to turn the boat each and every time.

My guess, and of course no harm was intended in the process, is that the passage at the of top of this thread was taken out of context.

Having written a bunch of safety columns with Tres Martin as the most excellent source, I understand how important it is to include all the variables he cites.

So I would ask after taking the course and being told you should turn your boat this way everytime, why do you not do it??

Is it really for the time your running hard and on the edge "like a race boat" or really practical for the go fast boater?

How many of you guys who took the course, learned this turning technique and impliment in daily boat trips?

I use it but not every time. It is not really fluid as just turning the wheel can be. Does it work though, yes.

In the end I learned some things from his class but most is basic things I know myself. I do feel his class is more for a first time cat owner or a high powered boat.

If it was not a insurance requirement, then I would have never taken the class and I feel I would be doing just fine like I am today.
