The "mystery" ship you inquired about is a Guardian class Chilean Coast Guard Ship. Launched 6 Dec 1995,
Commissioned 10 May 1995. Built at ASMAR's Talcahuano Yard in Chile. 1,650 displacement, 22 knots. 4-3516
Caterpillar diesels and a bow thruster.
I happen to have it from a "James" book. I saw the photo and said, " I know that ship." I believe it's the only one in it's class.
My guess is that "he who has the coolest looking navy wins?" That's my guess since it supposedly only carries a 40mm Bofors.
Thank you by the way for your web site. It's been a big help. I just moved to the Cambridgeshire area and had no idea of clubs
or some events. - - Phill
