Hi Giles Intresting observation.. if the boat or laser were tilted would the straight line transferred from the laser onto the curved hull surface (and painted on) produce a curved line when the boat was righted?? Lasers produce only straight lines because they rotate about a axis (of evil?) which is prependicular to the direction of the beam.of light. If the laser were set up so the axis (that word again) were not parallel to the axis of the boat it would still produce a straight line, just not parallel to the waterline, or perhaps parallel but above or below it. The question is, would that straight line be curved when the boat was righted, I say yes Keep sailin' Wayne ----- Original Message ----- From: "Morris, Giles" <giles.morris@unisys.com> To: <montgomery_boats@mailman.xmission.com> Sent: Friday, February 21, 2003 1:52 PM Subject: RE: M_Boats: Vibration
Just thinking about this, and I'm sure you got there before me...
The axis that the laser rotates in will have to be perpendicular to the plane of the laser and the waterline, otherwise the pointer will follow a curved path. Did I make that obscure enough?

Sybil,
Great idea for marking the "real" water line of the boat.
But now I've got my new toy and will have to play with it before I can try your idea.
Thanks for the idea.
Connie
