Off the topic, but I love that mark pictured on the website (where POR 56 is close reaching towards it). Looks to be the perfect size, with stripes to know when you spun it, a flag on top - really nice! Are they inflatable (it looks like it is but it's hard to tell from the picture? Can one buy them via Internet?
We use similar bouys here in Spain too - they are available from diving shops (the flag is one of the international 'divers below' symbols and is incorporated into the inflatable bouy). The POR version looks as if it's been painted with black and white stipes around it's base to make it even clearer if it spins around when hit - good idea! I have an internet diving shop site address here in ESP where you can buy them if you want it.

Well, they look really nice! Our previous experience with inflatable buoys around here was that (even when weighed down) they tend to "skip across the surface" (move around a lot) because they don't sink very deep... But that mark looks well "entrenched"...
Thanks for the offer Roy... I'll check our local dive shops here first (but I might e-mail you if they don't have anything nice like that).
