Greg,
All the guys have given great advice based on their experiences.
The most problems for me are the larger power boats in narrow channels. The obvious problems they cause is their belief that bigger has the right-a-way. This is true, but the pattern I see:
1. The term more dollars then sense holds true.
2. Watch and see that most do not use the correct trim for their speed, creating large wakes.
3. Note as they pass in close quarters almost ALWAYS, they never look back to see how the smaller craft handles their wake.
Sadly, most people with big money expect special entitlements. They feel more power & expect the little guy to lay down. If you notice many top earners have a long list of victims on their climb to the top.
I have learned over time that it's not worth it trying to SAIL in channels with traffic and/or current. I see the purist sailors with sails up, paying the price of wakes. I've seen masts & keels break, sails rip, boom shuttering and rigging exploding. I've witnessed people being injured, and/or thrown overboard.
The law states that any boat in Navigable waterways whose wake causes damage to another boat IS liable. So, after going thru your wake induced emergency, make sure you have binoculars to read the boat’s name in case he’s moving off quickly. Hail your local Water Nazi, marine patrol etc. to document. Tell them you are taking damage inventory & will update them. Call ahead to the next bridge tender & report this also to him. Give him the boat’s name & he will write it down as it passes. This is info you will need to sue the bastard.
Now for the wake handling, all boats by design will handle differently.
What works for me, as FLY mentioned is to turn to him. I try the “gently nudge method.” I try to show my intent but you don’t want to be too blatant, as he may be an ******* and decide he wants to show you a lesson.
As he passes (hopefully you have room), I turn my bow into the wake @ 30-45°. For me this keeps me upright instead of THE ROLL. You may also move your berth to a better spot and/or contact local authorities for more speed signs, etc. If you are with BOATUS, contact them. They may influence the officials for more or better speed markers.
I have many friends with large powerboats that are excellent operators, but there are the *******s & they will always be there.
