^Now things are getting interesting.
I'm quite familiar with the Alajuela, having met Mike Riding, (he had a partner whose name escapes me,) when they were working on the
plug, and a bit later when their "factory" was on the other side of the fence from the yard I was working at, (their foreman, a friend of mine, had previously been my supervisor at another company until Mike hired him away,) and have sailed on them.
Every indication is that the Alajuela weighs in at ~27,000lbs.
Even with full water/fuel/stores, and a billion other things you'd be hard pressed to get to the 34K of your
boat, or the 38K of the OP boat.
I would imagine that if you put 6 tons in an Alajuela the bobstay fitting would be way under
water, my gosh, 6 tons is getting towards 50% of design
displacement.
Now, if the guys in Port Townsend, (as I mentioned,) "played fast and loose" with the lofting and increased the beam, that would change the "Pounds per inch immersion", causing the boat to float higher, then a lot more weight in ballast could be added to bring the boat down to her lines.
34>38K is more than a Westsail 43, which has a LOT more waterline and beam, and a ton or so more ballast.
