There is another Alden 44 here in Panama. Its name is Indigo Moth and it's only three hull numbers away from ours. We have even met the owners, but have yet to visit each others boats. However, we did get measured by the Canal authorities together.
Getting measured is odd: you have to motor down to channel marker #6 at the appointed time and just hang out for a while. Then the big boat comes alongside and the official hops onto your boat.
The official was very cordial and claimed our boat had been through the canal in 1993 so he didn't even measure it; we just signed a few papers. I can't figure how he deduced that because the name, documentation number, and ownership has changed since 1993, but who am I to argue?
