Jolly Island Mark Island navigation

[Grove84]

Had a great afternoon on the lake yesterday and decided to navigate a new section of the lake for me. Was heading back from hole in the wall and decided to navigate Jolly Island - Mark Island back to govenors. Was following my chart and comparing it to the GPS on the boat. Then encountered the seam in my Bizer map. I relied on the GPS and the compass in reference to the markers and followed another boat which I try and avoid . While the outcome was positive and I learned a new portion of the lake after being on The big lake for 15 years. I am looking to locate a map that I can study this navigation route to become more comfortable with it,assistance is appreciated
