Actually, all the boats I have done have about an inch of "drag" in the keel (the forward end of the bottom of the keel is about an inch higher than the aft end) except the new Sage, which has 2" of drag. This gives the bottom of the keel a slight angle of attack and reduces the wing tip loss. jerry ----- Original Message ----- From: "Joe Murphy" <seagray@embarqmail.com> To: "For and about Montgomery Sailboats" <montgomery_boats@mailman.xmission.com> Sent: Sunday, April 10, 2011 10:51 AM Subject: Re: M_Boats: Bottom paint and water line determination
In my previous post I said I used the support that the keel rests on to use as the most level spot. I just wanted to add that after I launched SeaFrog, I was thrilled to see that the water line was perfectly uniform all the way around. So I guess the keel was the best place. I also said earlier that I started at mid ship just below the 5th lap. But this year I raised it one more inch. It was fine the way it was but that was only if I balanced everything just so. For some reason I was fairly diligent about doing this underway, but in the slip I found that it was so easy to stow more stuff in that cavernous port lazarette. (Hey Bob, maybe you should put the shallow laz on the port side where the engine and battery are traditionally located and put the 'vault' on the starboard side...) Anyway, as a result I have just enough list to bring the water line just below the water. Amazing how fast those pesky little barnacles mount up. Plus I got tired of hearing my sailing partners in their boats commenting on the fact that they couldn't see my waterline while I was sailing. But somehow they didn't mind drinking my beer!!!!

Joe,
What did you for reference for the fore and aft levelling? Is it okay to use the cockpit seats, with a level on them?
Thanks

As you can see from the pictures that Bob shows, I put my waterline just below the 5th lap at midship. To create the rest of the waterline I first leveled the boat. The tongue jack adjusts fore and aft. A floor jack on the axle adjusts the side to side leveling. Then I made a water hose level made from a 25' piece of clear 1/2' tubing. I filled the tubing with water. I had a friend help me by holding up the tubing right at the 5th lap. As I raised/lowered my end of the hose it would in turn raise/lower the water level at my friends end. Once we got the water level at his end to match the 5th lap, all I had to do was to walk around the boat and mark where my water level was at my end of the hose. Then tape above the mark. It's a little bit of a process especially with those wrinkles that we love so much..... until it's time to paint the bottom Joe Seafrog M17

Hey Joe.....I posted a message on this subject on Trailersailor.
I agree, start with a good barrier cote.

I painted the bottom of my M17. I just looked at the photo gallery of M17's in the water to see where the water line was at midship. That's the nice thing about wrinkle boats. You can measure it pretty easily. Now, having said that, I'm in the process of raising the water line an inch. I think that's just because I carry too much crap. And beer!! But I'd rather raise the water line than cut back!! IMHO, I would definitely start with an epoxy barrier paint. But I'll yield to the pros that contribute to this group.

THINKING, of painting a virgin Monty 15 bottom, where would I start to figure out a proper water line. If one was to poll the gallery could one find out how many keep your Monty's wet for the season? Thanks Smiley M 15, # 616. Very soon to arrive to its new home.
