I have found that wind direction is a big factor, but when you get way out on the big lake current and waves can be crazy and change. If I were to pick areas to fish for walleyes from a boat like you mentioned I would probably pick launches near Port Clinton , but wind direction is key. My boats are small too but not quite that small I keep a close eye on this situation also. The West side of the Western basin is a good place to catch walleyes too and it is sheltered somewhat from the Western wind.. Keep in tune with wind and wave forecasts and heed their warnings. Also a little farther East at Huron I have seen a lot of smaller boats on the water at the mouth of the river. A small craft can sneak out and find some deep water and still be able to slip back into safety pretty easy.

My experience is not nearly as great as many on this forum, but this has been my experiences as it relates to your question.

My 2 cents,

Kent
