Boats and motorcycles
"RCE" wrote in message ... Ok. Now that we all understand and agree on the mechanics of steering a motorcycle, let's consider this situation. Twin screw inboard. No wind. Little or no current. Helm hard over to port. Starboard engine at idle Starboard transmission in "forward". Port engine at idle Port transmission in "reverse". Which way will the boat move? Eisboch Being that you are slightly right leaning and have lost a significant amount of weight and your thrusters don't work, your boat will crab to port as long as you don't sneeze while facing to port or fart while facing to stbd. |

May not go anywhere considering engines are at idle Oh, it will move. I posed the question poorly. Better questions a Which way will the bow move? Which way will the stern move? Eisboch With the rudder in the neutral position the boat would pivot to port. With the rudder hard port one may think the boat may tend to move even more aggressively (bow) to port.... After seeing Jim's answer you have to understand that I *meant* to say "tend to move even less aggressively to port".......and "walking" port to starboard....... Yeah, that's the ticket! |
