Congrats John!

1 of the two happiest days of the proverbial sailors' life is approaching!
We have a P39, 1975 model &
hull #72. There's a world of difference between ours' & Your soon to be acquisition, however Bill Shaw designed and built absolutely Fabulous Vessels! You WILL Be pleased with both the looks esthetically inside and out, and most importantly HOW She Sails! Ours as a vintage 'racer/cruiser' maintaining IOR & PHRF #'s that worked while adding in enough 'creature comforts' to keep the 'non-speed racer' types, and families enjoying extended cruises. It's EASY to make 100nm in sunlit hrs, and we've done 200 more times than can be counted in 24hrs. You will never be disappointed with a well made
boat; starting w/"good bones" is the ticket. Don't worry about
electronics, what they have You'll likely want to replace. It'll (electronics) be Your likely most expensive upgrades after
purchase so pay close attention to that
survey & Make sure the
Surveyor verifies integrity on all those components.

HTH,
