Backing in is really quite simple
We just took delivery on a 410 which is basically similar to the 420. I was told to do the following:1. Stand facing to the stern. This way, when you want to go left, turn the wheel to the left.2. Go as slowly as possible, often times you only need to shift in and out of reverse to accomplish the moves.3. Begin at about a 45 degree approach, then turn sharply toward the dock. Be sure to have someone fend the port beam to bow area to avoid the dock corner. 4. As you enter, you will need to turn the wheel sharply to the boat's other side to correct the circular movement into the dock.5. Buy yourself two to three flat bumpers and place them at the end of your slip. As you reach them, leave the boat in idle reverse. This "parks" the stern and will allow you to adjust the bow, stern and spring lines so that the boat is centered in the slip. This parking thing is also done when you prepare to head out. It really holds the boat in place while the lines are untied from the dock cletes. And, the flat fenders prevents any marks on to the boat.6. The key to this is to go slowly, adjust for wind and current, and use the gear lever to take you in and out of reverse as you back into the dock.7. Backing a Hunter into a slip makes boarding easier with the scoop transome.Good luck,John Richards/v Jack's Place
