Thankfully, I don't know any jetski dealers - in Gibraltar or anywhere else. You *may* find that jet-skiers are more welcome on the Mobo forum: because some of your number have failed to recognise the needs of sailors in the past, you *may* find that we don't wholly share your enthusiasm!
But since jet-skis choose not to be boats legally when it suits them in avoiding the consequences of their actions I see no reason why a boating forum would expect to discuss them and agree with Thistle's reply.
Wonder why they should waste such emotions on inanimate objects. People, not machines under their control, may or may not be nuisances. There's enough water out there for all of us.
Jonski - as seems to be the norm on here now, a new user asking for advice is castigated because his form of water enjoyment does not fall into some others area of expertise. You will be treated with more respect HERE and frankly more likely to get a better quality answer to your question. Good luck /forums/images/graemlins/smirk.gif
The trouble is that it's easy to be a hooligan on a jetski. Tough with a long keel gaffer! As with thoughtless mobo drivers, the few idiots taint the whole barrel. True, we are all water users but I fear that is the only common factor and the best we can expect is tolerance between philosophies that are literally oceans apart.
If you are still on this forum (despite some replies) you could try Andalucia.com as they have a forum and a local there may be of help. I can't think of a supplier but if there is one it will could possibly tied to a motor or motor bike supplier/dealer. Obviously best bet (as stated) is manufacturers.
