A boat that sails well, was originally well built for its day. All older boats have issues, but the "project" should be restoring the boat to its original quality and modifying items you would like to change, but not to make up for bad design or build to start with. Everybody's eye for beauty is different, and I forget who said it but when rowing away you should want to turn around for another look.
Hinckley, Sabre, CS, C&C, Cal, Pearson (Triton and others), Alberg, Spencer (B.C. built), Bristol, Contest, SHE (UK), Rival, Contessa (26 & 32) and many others as well as custom boats from good designers, S&S, Peterson, Rhodes, Lapworth, Crealock, Herreschoff (probably wood), Perry, Tripp and others.
And the Vega 27 all except for one.....
