No, LWL is a straight line measurement just like LOA.

LWL is measured in a straight line from the water at the bow
to the water at the stern. LOA is measured from the stem fitting
(not the plow anchor, mind you) to the transom at its longest
point in a straight line.

Isn't the LWL measured from stem to stern along the path that the water
takes? Hence, for a given 'straight' LWL, a beamy boat would have a slightly
longer LWL than a narrower boat. Of course, this would mean that an estimate
based on a straight line measurement would be slightly short.

Yup, some subsequent Googling confirms - cheers.

Maybe you could sink it to the gunwhales and it'd be as fast as a
26.6" LWL yacht?

Ozzy, go to sleep NOW. You can't say anything funnier than what you wrote
above!

LOA (Length Over All) is a measurement from the tip of the bow, around the
edge of the deck - as in toerail - , to the edge of the stern). LOD (Length
Over Deck) is the straight line measurement you describe.

Therefore, two 30' yachts, one with a 12' beam and the other with a 10' beam
will have different LOD's!

a.. Length Overall (LOA): The extreme length of the ship along the

That's silly. Are you saying my cat's LOA is 9 feet longer?

I can find a number of sources that say LOA is straight line, not around the side. Here's
one:

The measurement your talking about may play some part in a handicap rule, but it certainly
isn't used in builders' specs.

I hate to say this but deep breath Neal is right and you are wrong.

LOA is a straigh-line measurement, including things like bowsprits and
sugarscoop sterns. It is what it calls itself: overall length. That's
what can make it differ from LOD, which is also a straight-line
measurement but of the deck only, not including things like bowsprits.

LWL (load waterline) is also a straight-line measurement.

So, in your example, two 30' boats with different beams will have
identical measurements for LOD *and* for LOA, assuming neither has a
bowsprit or other appendage which would add to the LOA. For example,
if both were 30' LOD but one had a sugarscoop transom, that one would
have a longer LOA than the one without the sugarscoop.

LOA----

You better measure tip on Bow to farthest projection on stern. That what
you pay moorage on. That my friends, is THE important measurement!!
