Notes

S&S #1956 and originally the SEAFARER 48.
The design was first introduced at the NY Boat show in 1969 and designated 'Queen of Show'.
It was one of the largest sailboats ever displayed there. It is thought that no more than 5 were built at the Seafarer plant on Long Island, NY. How many were built by Hughes is unknown.
Also called NORTHSTAR 48.
