Instead of going through the Graveyard, go further East over between Melvin Island and Chases Island. It's wide open over there instead of tight in the Graveyard, deep, and no rocks. Even with other boat traffic, you can stay on plane. I had a house near Suissevale for 20 years and can count the times I went through the Graveyard on my fingers with no repetition.
Why look for trouble?
