OK, I have to get this off my chest.....but it does include some "vandalism" which has left some guilt in me over the past 35 or so years. I was in high school and we had trailered my friends father's 14' boat up to Winni for some early Spring fishing (yep, he trusted us).
The water was extra high that year and I (foolishly) had no chart, though I knew the Lake somewhat. We were coming out of the cove in front of Idlewild between Cow and Ragged Island. the water was high enough to be above the (then unknown to me) unmarked boulder which is visible most of the time. I figured we were clear of the cove and any obstructions (having cleared the red marker) and opened her up to head back to Gilford. Oooops....we went clear over that monster rock, sending the boat in the air and busting the prop shear pin in the process.
The weather was closing in and we noticed some water starting to enter through a crack we created in the hull. Had to get the shear pin fixed...but we had nothing to use. We saw a cottage on that small Island between Ragged and Cow and quicly paddled over to scrounge. The only thing we could find was the screen door hinges and they worked perfectly! Fixed it, then nursed it back across the broads with the bilge pump running and made it on the trailer "safely".
Now, every time I see the scene in "On Golden Pond" where the screen door falls off the porch, I'm convinced it was inspired by that "petty theft" of my youth.
Whoever owned that Island at the time, we owe ya.
Now I'm wiser and more experienced and NEVER go anywhere without a chart.....or a shear pin.
