I think you would be hard pressed to make a profit by targeting fishermen as your main clients. Maybe you already own the property and accommodations, which would help, but building something from the ground up financing it all may be another story. When I go on a fishing trip it is just that fishing from daylight to dark and all I pretty much want is clean accommodations to shower sleep and eat. Seems to me but like most all other lodging around lakes, you would need to make the majority of your money from memorial day to labor day. No disrespect, but I personally could not afford BB rates on a fishing trip based on the number of hours I am there versus on the water. Grant it my wallet is not as fat ad others, but even when money was not a big issue a couple of years ago I would spend less on lodging to justify spending more on tackle. Good luck in your venture and hope you make millions
