Steve, did you jump in with both feet!!!
Steve,Everyone developes ways of docking. I understand your desire to make it safe and easy. If you are docking in a normally cross wind dock, the process is difficult and different every time with wind speed or current.You can rig your dock with soft line to help your docking process similar to the product you are looking at. One thing before you spend money is to evaluate your docking technic in each wind position. Then make sure you evaluate the wind on the way into and out of you slip.Some days may be rough even for the seasoned sailor, and when unsure, do a drive by and ask dockside people to help. ( this may open a new can of worms, just because they are dockside, doesn't mean they know how to help. Chose the dockside help when possible.) Learn which way your boat responds the best when backing or moving forward. The turn of the prop effects that. If it is an outboard, the side of the boat that the motor is mounted combined with the turn of the prop affect manuvering.One of the guys at my lake backs into his slip and does it the same every time.Wind or no wind he pulls past his spot,(his boat backs well to starboard, so he always backs to starboard.) He has developed a line system that is intresting.He has a bow line that will reach to the stearn. On that line, he has a stainless ring about 2" in diameter. As he approaches the dock in reverse, he puts the boat in neutral, steps off the boat, hooks the ring on the cleat at the end of the dock and tails that line as he works the stearn in. That line in the ring allows him to control his bow into the dock with his hand on the stern pushpit, 27' away.He practised this manuver again and again in no wind situations until it was a habit. He loves to take others sailing, he may have 4 people on the boat but when he is docking, stand aside, he is a singlehanded docker. If you have been out with him before, once he is off the boat, you know what might make things easier for him, but don't mess with his system.Most of docking is learning your boat. The pitch on my prop pulls my stearn to port. I mostly dock on the starboard side. So if I come in hot and hit reverse, the stern comes off the dock. If the wind is from the starboard, it makes a simple docking manuver difficult. It doesn't normally effect the outcome until the wind is about 15 knots. Then I recruit help or run like crazy to do the manuver.Steve, everyone is different. If you think this devise will insure that you don't mash the boat, great! Before you buy it, think of ways you can insure yourself of less expensive ways of secrue docking. That way you will be confident and not worry about some cruising to other areas. The wind and current are the things you must be aware of. r.w.landau
