I can take 4 adults fairly comfortably in a 21-foot boat. Groups of two or three are recommended for the most comfortable and productive fishing trips for walleye, smallmouth and crappies. For muskie fishing we can only take 2 adults.
The more people in the boat the more limited we are in types of fishing presentations and fishing in windy conditions. It is always recommended for larger groups to split up and hire multiple guides for a more productive and enjoyable experience on Vermilion.
