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?

I made a water level to mark the waterline. Attach a 2-foot section of clear tubing to the end of a garden hose and secure the other end of the hose to a stationary point a few feet above the waterline. With the bulk of the hose hanging below the proposed waterline, hold the clear section of tubing up so that it intersects the waterline. Fill the hose with water until the water is visible inside the tube at the level you wish to paint the stripe. The water level in the tube will remain constant as you work your way around the hull, so just mark and connect the dots to determine your new waterline. Works great, assuming the boat is level and the water isn't freezing... Joe Kidd M15 #207 "Poco A Poco"

Here's an easy way to remember what Connie and I have been trying to describe. "Did you hear about the fellow who bought water skis and spent the rest of his life in frustration looking for a lake that sloped?" Water in a stable enclosed area (lakes, basins, bowls, glasses, water hoses, etc.) will always remain level. Displace that water with a rock (which sinks) or a boat (which floats) and the water will still remain level. If the water is contained in a lake, the waterline on the boat will be obvious. Even if the water is contained in a hose, the same principle applies and the water level will still remain constant. Joe Kidd M15 #207 "Poco A Poco"

A while back I worked in Mexico on a powerboat tooling project, and in the absence of a transit we used a string to establ;ish the WL. We taped it to the stem with masking tape and one man got on the other end and slowly bent it around the boat, keeping it level, and another put little tabs of masking tape on it to keep it from sliding. Sounds hokey but it worked great. It was done by an old Mexican boatbuilder, who was also a master with a plane. Nearly everything I could do with a router he could do with a plane, and usually just as fast and as good. Makes you think.

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

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
