Thanks for the response, I have looked all over and can't find anything about it. The hull lenght is 15', beam is 6.5 ', mast hight is 21'. It is my understanding that it was manufactured in the U.K. in early '70's, hull #0325, the hulls are bright yellow, and red on top with "POLARIS" aft on both. The boat is in great shape, I am having a tramp made at a local shop and I am looking foward to getting the boat ready to sail. Hope this helps. Thanks Evalynn
