I just did a google search on the Oregon Coast and had a look at Ona Beach ... and by the looks you are going to have a fun time....
A suggestion for a yacht is do some research may be with NALSA and see if there are any other land sailors in the area and see what they sail, that type might suit you also.
If your just a little inclined to build a yacht, give it a go even if you did the metal prep work it would possibly take less than 1/2 a day for a preficient welder to weld it up. Its actually quite easy....
