Full Keel Westsail 32 Tayana 37 Whitby 42 Valiant 40 Bristol 35 example http://www.tgw.net/sailing/qca/jpegs...gdrawing_L.JPG http://www.macnaughtongroup.com/sovere2.gif Modified or cutaway "full keel" Nordica 30 Morgan Out Island series example (this one is a bit more cut away than others) http://www.libertysails.com/assets/images/sail_plan.JPG Fin Keel Almost every production (ie "brand name") boat Cal, Ranger, Columbia, Catalina, Pearson, Morgan, C&C, Hunter, etc etc http://www.catalina22.org/nsa/racing...s/image002.jpg This boat has the rudder taken off http://www.mudhead.org/images/Classifieds/side.jpg comparison http://www.tc.gc.ca/marinesafety/TP/.../Fig-1-1-2.gif http://www.marinewatch.info/keels.jpg http://www.marinewaypoints.com/learn...mages/keel.jpg Here is a boat specifically designed to gain some of the benefits of both fin & full keels http://www.macnaughtongroup.com/Anacortes%2032.htm Shoal Keel Could be anything, fin or full... just means that it doesn't stick as far down below the surface of the water. Bulb Keel Just like a fin keel, only with a big lump of heavy stuff at the bottom to improve stability. http://www.mallorca-bootcharter.de/media/v60/keel.jpg http://www.segelsport-hille.de/1/TRAILER%20J80%202.jpg Wing Keel One of those multi-purpose variations: the wing keel is just like a fin keel, only shoal draft with a wing like an airplanes at the bottom. This adds weight low down and also makes the keel more efficient with regard to lift/drag ratios (ie less leeway, higher speed). http://www.yachtsnet.co.uk/archives/...-wing-keel.jpg http://www.ospreysguide.com/ducky/im...rside-keel.jpg http://www.vacantisw.com/images/Articles/frontview.jpg Swing Keel Heavy ballast, pivoted with some means of pulling it up so as to sail in shallow water. http://www.northshore.co.uk/index.php?p=swing/swing http://www.romah.freeserve.co.uk/0im...el_profile.gif http://www.nanco.se/case_studies/bilder/idesign4.gif Drop Keel Similar to swing keel, only it slides up and down instead of pivoting. and something with a centerboard and a daggerboard. A centerboard is the same as a swing keel, except less intended to be ballast and used on smaller boats; also they usually pull completely inside the hull when 'up' whereas swing keels often don't. Daggerboards are just like drop keels only without the ballast (drop keels are sometimes called dagger keels); also daggerboards are used in much smaller boats like Sunfish & Lasers. Now here's a combination you don't see often ![]() http://www.mitchellyachts.co.uk/page3.htm One thing to bear in mind, this discussion of "the keel" and it's external form should not be confused with "the keel" as a structural member; keel & keelson are often used interchangeably in the structural context. Hope this helps, seems possible that I should have stuck with just some pics and not put in any words ![]() Fresh Breezes- Doug King |

Leaboards twin bilge keels Trying to confuse the poor guy? ![]() Actually when my wife & I first started looking at big cruising boats, one that got serious interest was a Bolger ketch with leeboards. While I hesitated, somebody else bought it. So what is a keelson? Interior structural member along the centerline, usually laid down above the ribs & tied into the floors but sometimes notched for the ribs & beveled for the garboard. Here's the best pic I could find on short notice, scroll about halfway down. http://www.amespointboatworks.com/Ca...Knockabout.htm This is a gorgeous boat too. Fresh Breezes- Doug King |

While I hesitated, somebody else bought it. Darn. Ive never seen a Bolger design in person. Pertty cool. I have always lusted over a 45' Texas Scow Scooner. Oh, and the sailing scow Alma in SF, CA. Now that is the most graceful shoe box I've ever sceen! So what is a keelson? I was hoping for a wise crack on the order of, "a keel made in Sweeden" Interior structural member along the centerline, usually laid down above the ribs & tied into the floors but sometimes notched for the ribs & beveled for the garboard. Damn, I didnt think anybody over hear knew anything about boats. Good on mate! Bob |

This one was a 45' gaff leeboard clipper-bowed ketch... hull form similar to the Thames barges, rather boxy (not hard chine) but with handsomely shaped bow & stern. Very shoal draft, pivoted masts, not so great as a passagemaker but a boat that could do anything including the canals. The design is called 'Bird of Dawning' (blech), I think a half dozen or so have been built. I have always lusted over a 45' Texas Scow Scooner. Oh, and the sailing scow Alma in SF, CA. Now that is the most graceful shoe box I've ever sceen! If you pay 5$ extra you can go sailing on the Alma. It's kind of fun even if you're herded on board with a gaggle of tourists. It just goes to show how much times change, at one point these type of boats were as common as pickup trucks. So what is a keelson? I was hoping for a wise crack on the order of, "a keel made in Sweeden" If I'd thought of that, I have said it. DSK |

Did you read about Evgeniy and the boat he built in his kitchen and lashed to the outside of his apartment? http://www.riverearth.com/seabird/20...1_archive.html |
