DCDivenut:
If you could pick one destination in the Caribbean that is not currently serviced, or underserviced, by a liveaboard where would it be and why?
N.E. Grenada: The Southern (airport) end is served by dive ops and a liveaboard (or did it give it up?) and is mediocre diving. The NE end is a delight but a bit distant and has some rough passages/not great harborages to hide.
Bonaire: Is saturated and after paying the airfare, hard to imagine people ponying up for a dive week that would be double in cost. Besides, half the fun of Bonaire is the shore diving and the restaurants. Aruba and Curacao? Not worth the bother.
Los Roques: Difficulty of air transit to Caracas as well as to Gran Roques, Lack of commercial infrastructure and food stocks to support a vessel (without having to make ongoing crossings back and forth). Many shoals. The diving is shallow and subject to occlusion of viz with moderate currents. This makes diving the many many ancient wrecks a challenge, but well worth it for the advanced diver.
San Andres (North to) Corn and the Half Moon Banks: Mechanical maintainance infrastructure issues, food supplies, as well as transportation to and from the area is limited.
The Bay Islands of Utila, Roatan and Guanaja: Because the infrastructure is weak to support a commercial passenger vessel mechanicaly and the inexpensive diving offered by the Roatan land based is roughly the same as what the current liveaboard offers.
The Bay Islands diving is largely untouched by recreational divers. What is known, even by frequent travellers there is the mere tip of the iceberg. Two weeks on a well supported vessel cruising Helena, Morat and Barbaretta (the Eastern tip of Roatan), as well as forays just around the East end to the North side when the weather would be good is an indescribable joy.
Also part of the Bay Islands:
Cayos Cochinos can be a difficult crossing with absolutely no infrastructure.
Cisne (Swan) for the same reason.
Belize is still under served. The cheap airfares (comparatively) make it viable. On land- everything you need to keep an operation running, kind of.
The Flower Banks? Weekend outings and well served. The Dry Tortugas? If well marketed and kept cheap, you could make a go of it.
The greatest problem with liveaboards is that they have to cater to the lowest common denominator. When you offer referral OW dives as part of a certification package while you're aboard, the ship simply can't plan to take you to the better dives (i.e.: the Tobago diving, land based vs. liveaboard)
Some ships have attempted to overcome this by offering 'special' packages on unusual routes, offering gentle warnings to first timers. Sometimes this works, but they haven't been big sellers for most, however the Nekton fleet has done well with special exotica offerings.
If you want an example to follow, look at how Nekton operates. This is what I believe to be the best liveaboard operation in the Caribbean, and in the top ten in the world.
Why? How much money do you have to spend on this project?
