Re: Big boat handling

Or learn your stopping distance. You can use the bouy trick noted above, just don't hit the buoy . Approach the bouy at a few different speeds, slow ahead, dead slow etc. Then observe how long it takes the boat to come to a complete stop when you stand on it in reverse, half reverse etc. Make a mental note of how many boat lengths it takes to stop the boat.

You can do the same thing with your turning radius. Your GPS track can be useful to generate a turning radius. Just go out, slow ahead, put the wheel over and observe, then measure the radius with the chart plotter and make a mental note of how many boat lengths the boat takes to turn a 360. Then do the same with backing and filling. Obviously backing and filling will give a much tighter radius.

You may note these figures with diagrams are published on the bridge of pretty much every commercial vessel; crash stop distance, turning radius. Pro ship handlers know with a pretty high degree of accuracy how much room they need to stop, turn and how close they can bring their boats to the dock before they bump.

That is strange. I've driven and owned bikes in both the UK and Germany (and other countries as well) and all the equipment was placed identically. What was the British bike and what year was it?

Re: Big boat handling

Before 1970 many bikes had their shifters on the right side. Most British bikes and a few Italian.
as well. It was random. HD offered both. So some left and some right. Then in 1974 US government mandated all bikes sold in the US were right foot brake. Still many flat track race bikes remained reversed so you could shift in a left turn as most tracks are run. And the rear brake doesnít matter much anyway.
Now itís uniform throughout the world to the best of my knowledge. Also prior to 1974 shift patterns were fairly random. Now one down the rest up. That was also mandated by the US government although cars can still have any pattern they want.
Bike was a Birmingham Small Arms BSA circa 1960. Bought it used. Replaced it with a Norton which had the conventional set up.

David, any chance you could have a motor/prop offset from center .
If offset could explain LH prop pulling to sb in reverse.
I sail on an very old wood gaff rig oyster dredger (50' on deck) with prop offset to sb,
turns to port very nicely, starboard not so good.
And they really do take longer to stop!
