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

Westsail 32
Tayana 37
Whitby 42
Valiant 40
Bristol 35

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

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
