Hey Jerry, I like that Mexican solution. It seems to me that the use of any type of transit or laser level requires that the boat is level. To me that's always been a problem, short of putting the boat in the water. The boat needs to be level in all directions and the only place I can think of that would possibly give an accurate reading is the v-berth and that's not guaranteed. On the other hand the Mexican method only requires that the boat be only parallel to the surface it's setting upon. Well, all that being said, I don't know how to get the boat parallel either. How did they do that? Rick M15 #337 Bluebird

I've always done it with a transit, but a laser level should do fine. When you finish one side, without moving the level mark a spot on a wall that you can see from the new side, which will set the level up perfectly. Once I worked on a powerboat tooling project in Puerto Penasco, Mexico (I was a gringo wetback) and the Mexicans struck waterlines with a long string; a bit longer than the boat. They cut a stick to the len gth equal to the height of the waterline above the pavement, marked a starting place on one end of the boat and attached the string there, with the other end attached to the pole. The pole man slowly wrapped the string around the hull while the helper taped it into place. It worked surprisingly well, but it does take some skill and a good eye. Better to go rent a transit.

M sailors, A couple of months ago I recall someone out there asking how one goes about accurately painting the waterline on a lapstrake hull....like my M-17 "Little Breeze". A good question because my last attempt was pretty sloppy (I had a difficult time treading water while trying to paint ). This afternoon while working in the shop I got an idea which I am anxious to try and wondered if anyone had already tried it. Among my many tools is a laser level. What if I put "Little Breeze" on her trailer.leveled her up fore and aft and athwart ships, set the laser level up about 20-30 ft away, adjusted it to match the existing waterline mark at any place and then penciled where the laser line was along the rest of the hull. As soon as I get a clear (not raining) day I'll try it and let you all know, in the meantime, if you have any comments, or have already tried it, let me know...Regards. Arnold Sharpe, M-17 #265, "Little Breeze"
My M17, "Griselda", still has her origonal factory applied boot stripe and, I assume, the basic hull molding is still the same for the newer models. Would it help if I gave measurements to fixed points for the bow, midship and stern points of the boot stripe? These points could be duplicated on your hull and boat leveled to those marks. (the surface doesn't even have to be level if it is just flat) The line could then be drawn using a stick cut to the proper length to measure from the ground to the WL. Just draw a mark at the top of the stick at the fore and aft end of every strake along the length of the boat and "connect the dots" with masking tape. I have used the "stick method" several times over the past 50 years and it has worked well for me especially for lapstrake hulls. Let me know and I will go out back and take a photo and measure the reference points. Just don't be surprised to see some of the scroungiest paint you have ever seen. After all, Griselda is 35 years old and was last painted 20 years ago. Hull paint is next on the refit agenda when I have a couple of warm days. Ron M17 #14 (fin Keel) Griselda

And if you don't want to spend the money on a transit, I bought 25' of clear plasitic hose at Ace for $8.

Wrong time of the year for this, but the best way, if you don't have a boat handy with a WL so you can take some measurements, is to put the boat in the water and mark it fore and aft. Remember that the bottom of the strips should be about an inch above the true wl, and the top of the boot top should taper larger as it goes forward. jerry ----- Original Message ----- From: "Rick Langer" <farreach@optonline.net> To: <montgomery_boats@mailman.xmission.com> Sent: Friday, December 05, 2008 1:52 PM Subject: M_Boats: Waterline idea
