I always wondered how Boater's World stayed in business, but also noticed that they had lower prices than WM. As noted above, I would go into the stores, and they either had no one else shopping, or maybe one other person. And the people that work(ed) there were completely clueless when it came to helping or giving advice about the products that they were selling.
Not that the WM people are much better with advice or product knowledge, I have found them to be hit or miss depending on time and location. But every Boater's World that I ever went into had few customers and staff with little expertise in the products that they were selling.
