Hello all, I've just stumbled onto this forum/thread hence the very late input to the Delta boats topic. If you are not familiar with it, there is a very good vintage boat compilation/directory done by a Midwestern fellow by the name of Bob Speltz. He spent much of his life gathering information on vintage small to medium sized boats and prepared and published a series of seven books called "The Real Runabouts". It is still available via the ACBS ships store. In volume 4, the "Outboard Edition", on pages 120 thru 124, there is a chapter on Delta Boats. Lots of info here.
As most of you have figured out, Delta Boat first appeared on the scene in 1948. In 1949 their first black and white, four page brochure was issued describing six models offered for that year. There is a chart showing the particulars for those. Boats in that chart along with some pix were 12',12.5',and 14.5'. The boats of this period were cold molded construction done in-house with a combination of fir, birch and mahogany veneers bonded with Weldwood resorcinol glue. White oak transoms, knees and stringers were installed after the hulls came off the moulding plug. Later in the mid fifties and the early 60's the hulls were molded by US Molded Shapes Inc. of Grand Rapids ,Michigan.
The severe economic conditions of 1963 and 1964 put the company down.
Delta produced some of the sleekest and most advanced designs of outboard runabouts that was possible to do in wood construction. They also offered a big list of custom options, including paint, trim, hardware, seating,
deck layouts, flooring material etc., etc.. They also offered complete kit boats and I think that via these, some left hand configurations were built.
Looking closer, I see that some "lefty" models were offered thru the middle 50's - among them a 1956,15', "Sassy".
An interesting sidelight here is that a model that is being called the "Sexy",
is actually named the "Sassy" shown in a 1962 colored brochure at 15' and 16.5'.
Anyway, there is a LOT more info here in Speltz's chapter and if anyone wants confirmation of your particular boat, maybe it can be gleaned from here in the Real Runabouts. There is no hull number info though.
