Here's my idea. Matt's right, we probably should start another thread for this, but before we do I'll outline the concept and the logic. This might be a little long winded, so try to bare with me while I pontificate.
The problem is one of competition. The fishermens collectives can make the rules as they choose because they control access to the habours and the boats. If you could find a way of introducing some competition between fishermen you would breakdown their consensus and they wouldn't be able to reach these nice cosy arrangerments with each other.
OK, so how ?
Well, this is a bit of a leap - how many of us have had a near miss with a fishing boat recently. I've had three near incidents and witnessed another in as many weeks. All as a result of less than aware fishmen at the helm of the dive (converted fishing) boat. This got me thinking there ought to be a special license for diveboat captains. This would improve safety and as a by-product introduce a schism in the fishermans collectives that would provide the competition needed to open the market.
The first task would be to design a course, standards, and certification procedure for diveboat captains. This shouldn't be too hard, you could plagarise existing courses from BSAC/CMAS and localise them.
Then you would need to persuade a certification agency to take the course on, or alternatively, start your own. Then train some instructors.
Meantime you start to actively publicise the dangers inherent in todays current boat operations. It shouldn't take too much effort to get the ball rolling. After that you introduce your certification as "the answer" and encourage divers to ask for "BoatSafe" (or whatever you decide to call it) whenever they sign up for a dive.
It would take a while, and lots of cash, and a fair bit of effort, but within a year or two operations without "Boatsafe" certification would start to loose business to those that do.
One of the primary requirements of "BoatSafe" would be that all captains of diveboats would have to be certified divers. This would encourage the creation of specialist dive/boat businesses in the harbours and discourage oportunist fishermen from just renting a few tanks and taking people out weekends on the fishing boat.
Once the fishermen are the divers, much of the problem starts to go away. A good example of this is the situation at Kumomi in Izu. The original fishing/boat operation has been joined over the last two years by another 4 operations, two of which are specialist dive/boat operations. These newer operations are far safer, have better boats, are more aware, cheaper, and more flexible. One of them has introduced another 16 sites to add to the original two. The result of this is that Kumomi is now one of the cheapest places in Izu to dive.
Just as well too, cause it one of my favourites
So I propose a new thread where we discuss the things that we might include in a "BoatSafe" certification. (including perhaps, a better name).
