In this episode of building the Haven 12 1/2 I begin building the centerboard & centerboard trunk, This part of the Joel White designed Haven 12 1/2 is what makes it differ from the Herreshoff 12 1/2 that the Haven 12 is inspired by. The centerboard trunk is also connected to the boats bedlogs. I also discusses the reclamation of lead bullets for casting the counterweight for the centerboard.
