If it would be seen as an unfair advantage to have these units on some boats but not others the display can be taped off. As long as the unit is on the boat and turned on it is archiving the data for display later. Ther is some other outfit that will put their "bug" on each boat and collect all of the data from a regatta. I think this was done for the Key West Race Week. Sound a bit more involved but may be worth checking into. I think they give you a finished package that can be sent around ekectronically.

One thing about the Velocitek verses a regular GPS is that I think the refresh rate is faster and as someone said just the speedometer alone was worth it, it is for me.
