Fully Tek and I both run primarily technical charters with trailerable boats on the Great Lakes.That's something I've never done in all my years of diving. Where you going? Oh cool. Sign me up. Here's my deposit.
We aren't going anywhere unless someone tells us where they want to dive and books the boat to make that happen.
I operate on 3 of the Great Lakes, Fully Tek operates on two of them. It isn't unheard of to drag an oversize load over 1000 miles for a charter. I have a charter next year that involves 700 miles of trailering and two ferry rides with a truck and oversize trailer. A large part of that trip won't be refundable regardless of if we run or not. When I go to Whitefish point for the month of September, my first 3-4 days charters are just covering expenses to get there and run.
So, while I do refund for weather and mechanical issues, I also fully understand why he doesn't. Especially if you are just going somewhere for a week and get blown out for the whole week.
It is different than hopping on a Horizon or Rainbow Reef boat for a quick run out to the Spiegel Grove.
