Please don't respond that other things kill loons, we all know that. However I would be interested in data that shows loons are NOT effected by boat wakes.
Hazelnut wants me to post the bow numbers of boats that kill loons. Sorry, I can't do that. I will fall back on the knowledge that bigger boats have bigger wakes.
