Notes

S&S design #1631.
Also called KESTREL 22. ‘DAYSAILOR’ is a designation used here for at least 2 versions of this yacht. There were actually 2 deck layouts and 2 accommodation plans offered, resulting in four models: CATALINA, NASSAU, NANTUCKET and MONHEGAN. The ‘NANTUCKET’ version, shown above, has a smaller cabin and longer cockpit.
Stern overhang seems to have varied between versions, (possibly to accommodate the outboard motor well). The original S&S design lists LOA as 22’. KESTREL seems to be an earlier name that Seafarer gave to this design.
By 1970 a boat with this same profile was being promoted by Seafarer as the SAIL’N TRAIL 23 OLYMPIC.
The later SAILMASTER 22, by the same Dutch builder, but sold by another American company, is the same design though it was assigned a new design number. (#1743)
Further adding to the confusion is the later, American built SEAFARER 23, which is a completely different design. (Rig dimensions are from the original S&S sailplan but are not necessarily consistent from one boat to another.)
