Default LORD NELSON 41 QUESTION

Sure, I'll rant about heavy displacement boats, Pablo. We've sailed a
Westsail 32 for years and years and loved it. You can NOT escape the
compromise between speed (aka "performance") and seaworthiness.


???

Several misconceptions here. There are many completely different &
unrelated ways of evaluating any given boat's performance... for example
light air, VMG to windward, etc etc. Speed of sailboats is not as easily
quantifiable as, say, speed of two different makes of car. Even with
cars, you can compare top speed, speed in 1/4 mile, speed through a
slalom, etc etc. Will you say that comparing the speed of sailboats is
less or more complex? Then consider the attitude about racing boats &
speed, ignoring ratings... bad idea. A fast boat with a faster rating =
loser, but it may be a great sailing boat. The most successful racing
boats are designed so as to sail very slightly faster than the rating
rule thinks they should.

Then take a look at seaworthiness. What is it? (insert book here) There
is certainly no easy linear comparison.

Agreed.

... excpet that very slow boats have a
harder time avoiding bad weather.


Well, they can stay in.

For some examples of boats that have unquestioned seaworthiness and
can sail rings around a Westsail, see the Valiant 40, Pacific Seacraft
series (34,37,40, and some others), and Deerfoot at the top of the
scale.


And the Deerfoot isn't even heavy displacement.

... One rule you will find is that you can have a cheap heavy boat
that will hold together, but building a strong and light boat is
expensive due to the higher tech materials and expert labor required.


Agreed, but I'd go one step further and say that 1- "heavy" doesn't
necessarily equal strong. For example, those very very thick old timey
fiberglass hulls that some folks rave about have a very very low
glass/resin ratio... and resin isn't what makes it strong. 2- a very
heavy boat is going to impose greater loads on it's structure & rig (and
on it's ground tackle & it's crew).

If you go for cheap and light (see Hunter and Bendy-twos) , you wil be
making a compromise that might not be the best for long voyages. On
the other end of the scale, if some low budget Chinese yard built a
Westsail knock-off with very poor materials, they could make the boat
weigh twice as much as a Westsail 32, be half as fast, and still be
much LESS seaworthy than the original.


And a lower ballast ratio, etc etc.

I'm not a big fan of heavy-heavy cruisers, and detest the faux Colin
Archer designs (insert book on characterisitics of redningskoite), but
the Lord Nelson is above average. At least it will go to windward.
