Good site! Some excellent reading suggestions in there, particularly Solent Hazards and Wight Hazards which are essential for us yachties but most powerboaters don't seem to think relate to them!
I hope you don't mind if I make some suggestions that people may find useful:
A couple of real-time weather stations you may want to add as well for Lee on the Solent and Cowes
http://www.ivegotwind.co.uk/ - Lee and Hill Head
http://www.cowesharbourweather.com/weather/ - for Cowes
http://www.greatweather.co.uk/ - for the most comprehensive weather related links on the web!
And for tides at Portsmouth -
http://www.pol.ac.uk/ntslf/tides/?port=0008
http://www.gafirs.org.uk/ - the Gosport and Fareham Inshore Rescue Service based at Stokes Bay.
It may also be worth adding the VHF lists for the marinas, sailing clubs and Harbourmasters in the region. There's a list on here somewhere, perhaps you could, with John's permission, simply link to that.
I really like the site, I will be back and forward watching it evolve!! (If you do a "Solent Ribsters you're likely to meet gallery" then I'll send some pics!!!
PS - Where in Hampshire are you? I'm guessing that you know your rib is named after a caravan park in Hook!!!!
