Re: Teach me how to backup into dock?
Got me, I've been struggling with this for a while now, my boat turns perfectly left in reverse, but goes straight backwards with the wheel turned to the stop trying to go right. A big PITA...I'll get it right sometime.

Sounds like "tranverse thrust", the bottom of the prop is throwing water sideways pushing the stern of your vessel. One way to deal with this is to swing the leg the other way and give a little shot ahead to swing the stern to the desired direction.
(edit) Looking back, I realize I didn't explain very well.
In addition to thrusting ahead, the bottom of your prop throws water sidways like a water wheel, this effect, called transverse thrust, is most noticable in reverse a slow speeds.
If you have a right hand prop (clockwise) like most, in reverse the bottom of the prop is throwing water towards the starboard side of the boat pushing the stern to port.
Try this out in an open area as it takes some practise. Put the engine astern with the wheel hard to stbd and allow the boat to gain some momentum astern. If the boat is not turning in the desired direction fast enough (anti-clockwise looking from above) then in quick series of motions, shift to neutral, turn the wheel hard to port then give the engine a little shot of ahead (not enough to stop the astern momentum) which will turn the boat in the desired direction. Neutral again and turn back to hard to stbd and then reverse again. Repeat as required.
Hope this helps.
