Get a Navi GT-31 and a waterproof pouch. WindSurfnSnow sell Navis. I use a Paqua Midi I bought from Whitworth Marine. I would imagine both would do mail order if you are far from Sydney.

Maybe a shop closer to you sells this gear too.

In regards to software to retrieve results from the GPS you can purchase Realspeed or use the KA72 site.

Give Sam or Chris a call at Wind surf n snow on 9971 0999.
They have all the latest GP stuff and packs to put them in.
Its addictive, welcome to the club

I called Sam about gps yesterday and he said they out of stock but expecting some more in a couple weeks.

I will prob pick one up then as well and look for a Botany team to join.

Hinch, join a team, have a sail and post your session from your GPS reciever.
Session only counts if 2 team members sail on the same day, doesnt matter where it was. In Sydney there are the Cockies and the Double Demerits.
Everyone pretty much knows everyone so depending on where you sail pick your team. Be careful though, there are some pretty strange people on the Demerits
