Lyndon, bring it down to the club next Saturday and we can have a play with it. If it can generate a GPX file then you can definitely use it to see Google maps etc of your data via the www.ka72.com website.
If you start posting 40 knot peak runs then we might need you to buy a new GPS! But for just cruising around formula sailing it should be fine. Geoff used to use a Garmin etrex before he bought a GT31, maybe chat with him. His biggest problem was that it didn't seem to record anything about 25 knots peak speed for him.

Look us up on www.gpsteamchallenge.com.au - Lake Macquarie team.
Cheers
James
