I am the inventor of the BullsEye Boat Sight that is a part of recent discussions. The website bullseyeboatsight.com provides more info and videos with how to use of the product and how to install it on boats. The BullsEye has been tested over 2 years up here in Minnesota and 2 winters in Okeeheelee with dozens of drivers from 6' 5" to 5' 6" on the top brands of boats. I will try to assist with some answers to questions and comments as we go along here. It is a very useful affordable way to assist drivers of all levels to improve a little or a lot in providing the best and most consistent drive path. Trust me, this thing works or your money back! More later.
