Sometime in the early 1950's my parents owned a 30' Spencer (?)
sailboat. I seem to remember that there were only 6 of them made and
that they were made by the Boeing Company. I am curoous to see if
there are any left or where I could get some information on these
boats. I believe they were made sometime in the 30's or 40's

If the boat was a Spencer, this site may be of interest to you:

I seem to remember it was a spencer, but not from the company you sent
a link for. I think spencer was the design name and Boeing made a few
of them to try and diversify during the depression.

Found one maybe for you, here. http://w3.gorge.net/bgord/

Also, I ran accross an excelent site that will hunt down boating
related questions and come up with an answer for you here.

Hope this helps.
