The text of the Arava article indicates that the owner felt more
ballast was needed. It would be interesting to go sailing with the
owner and designer both aboard and find out if they were in
agreement. PCB is quite up-front about giving boats a large sail area
and expecting the owners to be savvy enough to reef early. I'm sure
many of them nod and say "yes, sir, yes, sir, three bags full, that's
fine with me." However when their boat is rail down in a 10 kt breeze
they call for more ballast.
On the other hand, owners take pride in an under-rigged boat. "She
carries full sail in a 20 kt breeze", wrote one owner about a non-
PCB boat. I thought "she could use more sail in drift."
One sailor who went against the trend was Alard Coles. In Heavy
Weather Sailing he describes how he had the rig on one of his racers
cut down in size. He said it made her slower, but a better boat.
One last observation: folks used to keel boats are often unhappy with

put a keel on his Norwalk Island sharpie, and/or some folks in
Australia did. Designers are greedy for draft, because it increases

shallow, the designers don't pay the price.

(Post-last observation: those light pole masts on Arava must be
pretty heavy. Lighter masts might be a better investment than more
lead for the bilge.)

Thanks Perter, What i meen by dory is with a flat bottom when the
flair of the sides becomes close to 45 degrees it seems like a dory
to me. I think ARAVA is an inlargement of SEA BIRD and very much like
the SERPENTAIR in hull form. I think that they are dory hulls with
built up sides. Bolger has produced many designs like this, REDZINGER
for one. for some reason the french seem to be into this multi chine
form alot. Jake

It's interesting you would call her a dory. I thought of her more of
a ply adaptation of the Colin Archer type. I'm sure her sailing
performance is modest - and I would certainly want a different rig -
but she has a lot of capability in a short boat.

Hi, I would like to get some info on a design called ARAVA, any pics
or study plans would be appreciated. She is a multi chine dory of a
sort. Thanks Jake
