Burt,
I followed your lead and used
http://www.st.nmfs.noaa.gov/st1/CoastGuard/index.html to search for the hull numbers of the Krogen 38s that names were listed for but there weren’t any hull numbers.
DORIAN is hull number UOI381401283 i.e. hull number 40. She was previously named EMERITUS. The builder is listed as United Oceans Ind. Corp.
HELLO TEXAS is hull number TMU381540284 i.e. hull number 54 She was previously named CYCLONE and AEQUANIMITAS. The builder is listed as Fu Hwa Boating Co. LTD
PELLUCID is hull number TMU381501184 i.e. hull number 50. She was previously named CHICKEN SLOOP. Funny name for a cutter. The builder is listed as Fu Hwa Boating Co. LTD
There is a listing for LIBERTE as hull number CBK38083A890 i.e. hull number 83, but her documentation expired in January of 2006. The builder is listed as Asia Boat Builder Co LTD.
I also looked up PEQUOD which I belive was Jim Krogen's first 38 but couldn't find it. I did find PELICAN which I belive was Jim Krogen's second 38 and turned up hull number TMU38174E787 i.e. hull number 74. No previous owner or vessel name. The current owner is listed as living in Satellite Beach, FL. the hailing port is also Satellite Beach.
