Looked up the article John and checked in all my articles listing the USCG boats from around that time – sourced from various UK , US & French magazines – the Halmatic was definitely never used by the USCG – so as the article says it was purely finished in USCG guise as the builder liked the colour scheme.
Trawled the web extensively with no sign of any military versions of the 65 – lots of flying bridge types for deep sea sport fishing however.
Unfortunately my plan is also very indistinct other than the basic hull, but you could refer to the German Rescue Boats for ideas on the daughter boat . Armament from the USCG 41 ft utility boats would suit – plethora of pictures of those on the web . The 82ft Point Class armament might be a little much for the scale..
Also checked Sarik for the plan – not listed as far as I can see
