I doubt it. Snorkeling is OK. Never heard of anyone using it to dive and I've been there 6x. Generally the only boat dives you can go on are the resort you are staying with or getting tanks from if you are staying at a private condo. FWIW, I went there once, and figured it wasn't worth the $75 trip (years ago, probably more now) and hassle of being on a boat with the inevitable newbies cutting bottom time. Never have stayed at a resort with boat dives as part of the package. If you do at least that's a spot you can't get to from shore. Most of the rest of the dives you can. You can even do some 'wild side diving from shore, if you know how (not easy). What I like about Bonaire is going where you want, when you want, and diving the way you want. No schedules.
Got this from one of the reviews about the taxi:
[The only way to dive here is on organized boat dives.]
To Air is Human,
To Respire, Divine.
