Tod, Maybe you posted and I missed it, but did you make the rudder cover or did you have it made? Details please. It looks very nice looking. steve Steve R.

Hi Giles, Two Martinis later - stirred, not shaken - let me try and clear up the problem. First the boat will have to be place on a flat surface and adjusted so that the water line is parallel with the surface. You then also have to make sure that the boat is level - Port to Starboard - Now you have to set up your laser so that the laser is parallel to the floor. Then you have to adjust the height of the laser (always keeping it parallel to the floor) so that it hits the intended water line (a vertical adjustment). Now, if you sweep the laser from bow to stern, it should define the waterline. It is determining a plane. and that plane is the waterline. Hull curvature doesn't enter into it, since the laser plane will cut the hull to match your adjusted setup height of the laser. You are right, if you don't have the laser in the same plane as the surface that the boat is sitting on. Then you can probably draw waterlines that would put Picasso to shame. .............but the Navy does that when they camouflage paint their vessels. If someone objects, say you are the Navy Auxiliary! Once the snow is gone, and it's time to do boat work again, I'll report on the ease or difficulty I had with my intended "solution" Connie

RE: M_Boats: VHF radio use

>VHF use was weather monitoring, and emergency use Weather transmissions are on a different band, but most (all?) marine VHF sets have the ability to receive (not transmit) on the weather channels. (BTW: My wife's car radio receives weather band, it's so useful that I can't think why they all don't). The VHF channels are assigned for different purposes. There is a list at http://www.qsl.net/tcarc-ntx/marine.html . Generally, you would listen on 16, and switch to another channel (e.g. 78) to decide which restaurant you prefer. If you stay in US waters and aren't required to carry a VHF, then you don't need to buy a license. Otherwise, you do.

Forgive my naiveté, I'm not a radio user, but I'd always understood that VHF use was weather monitoring, and emergency use. And hasn't the FCC rules recently changed so no fees or associated licenses are required as before? Thanks. t Tom Smith & Jane Van Winkle Sandpoint, Idaho M15-345, Chukar

>handheld and fixed unit Anything aboard an M-15 is likely to get wet (true of any boat, really) so I would want something submersible. The antenna height is probably more important than transmitter power, but looking on the West Marine site I didn't see any handhelds with the option of plugging in an external antenna. That's a pity because it would be a good solution. But perhaps they all have that option now (my Standard handheld doesn't). My own preference would be a handheld, both for convenience and because the best radio of all is the one you have with you. My handheld gets a lot more use, even aboard Dolphin which has an ancient fixed-mount VHF. Giles Morris Arlington VA Montgomery 15 "Umiaq" Vancouver 25 "Dolphin" Miscellaneous small craft

If I work at it long enough I can make the simplest thing complicated. Just rambling, and this is of no practical interest, but... Imagine that the laser pivots around an axis (say, a photo tripod) that's tilted back (away from the boat). At the center of the boat, it'll be pointed higher that it will when it's pointed to either side. So the line on the boat will be curved downwards at each end (or up in the middle). If the tripod is pointed straight up then the line will be straight. That's only looking at it from the side, of course -- if we look down then it curves along the side of the hull - but it should at least follow the level of the water (assuming we got it in the right place. So the waterline curve is never straight in 3 dimensions, and only in two when we transfer it in a particular way. I wonder, too, whether we actually want it straight. If the boot stripe is a constant width then (I'm no artist but) I'm not sure it looks right on hull that's curved and has a sheer curve (rather a graceful one, I think). Oh, boy! Talk about needing to simplicate things. I never did paint a boot stripe on Umiaq, and on Dolphin I just followed the line molded into the hull -- which turns out to be several inches underwater, so my boostripe is underwater and (because Rustoleum doesn't work as anti-fouling) looks like a strip of green shag carpet running around the hull just under the water.

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(a)unisys.com> To: <montgomery_boats(a)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.

Rendezvous?

Not to change the subject....well maybe to change the subject....are there any plans for one or more M-Boats to assemble this summer, other than the pending group going to the Keys? As in CBR 2003 or other? I need to make some vacation plans. Howard
