CHH, you know firsthand about the costs involved and I've helped pump gas into your boat and watched the numbers fly up into the stratosphere, so I get the part about fuel cost.
But there's some things that don't mesh with $250 for rigs which can be found 20 - 30 miles off. Isn't Stetson 60 miles off? Double the distance, only $25 more?
In Florida, Oriskany trips are $150 and it's 22 miles off. Plenty of six-pack operators doing well going out there, often carrying 3 or 4 people. Trips from 15-20 miles run under $100. And locals complain of the high rates.
They get more dive days, true. But while weekends are busy, weekdays are much slower. Note we booked our Friday trip just a week ahead, and we had our pick of charters. It's hard for me to justify $200+ for a 2-dive rig trip when I can go to Florida for the weekend and get 6 dives for not much more.
I would do a lot more local rig trips if the cost was around $125. That may not be feasible here but adding a third dive to a $180 trip brings the cost per dive back to that level. The Flower Gardens are really a pretty good deal, about the cost of two rig trips and offer much better diving (and food).
I wish the Flower Gardens were about 30 miles offshore, this area would be a diving mecca.
