Islander36 or Catalina38
Look at a Tartan 37 from the 70's: The most popular model was build with a centerboard (draft from 4.7' to over 7').
Great pedigree, like the Catalina 38, she is an S&S design. She is fast, well build and has a very functional interior.
They were (and still are) very poular on the East Coast and in the Great Lake areas.
