In my quest to better understand keels and what the differances are can
someone post boats that are fitted with the following keels?

Full Keel
Fin Keel
Shoal Keel
Bulb Keel
Wing Keel
Swing Keel
Drop Keel

and something with a centerboard and a daggerboard.

thanks,

Why not go to a website where that information is readily available and
where you can see the hulls cut away, external features, etc. Many
boats can be ordered with different keels....

Modified or cutaway "full keel" Nordica 30
Morgan Out Island series

Fin Keel

Almost every production (ie "brand name") boat
Cal, Ranger, Columbia, Catalina, Pearson, Morgan, C&C,
Hunter, etc etc

This boat has the rudder taken off

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.

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).

Swing Keel

Heavy ballast, pivoted with some means of pulling it up so
as to sail in shallow water.

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

Finally, something we can all agree on.

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.

This is a gorgeous boat too.

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!

I was hoping for a wise crack on the order of, "a keel made in Sweeden"

Damn, I didnt think anybody over hear knew anything about boats.

Good on mate!

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.

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.

If I'd thought of that, I have said it.

Did you read about Evgeniy and the boat he built in his kitchen and
lashed to the outside of his apartment?

Wonder what the neighbor's upstairs thought when the mast went up!
