Stainless steel is an excellent choice for many applications, but when immersed in wood and when in contact with salt water, its anti-rust ability is lost. In principle, the situation can be helped by enclosing the metal with epoxy, but an easier option is to replace the metal. Bronze is an excellent alternative to stainless steel in places where load strength is not important. That’s why I chose a bronze bottom valve on the bottom of the water ballast. The valve was attached to the body with bronze screws.
Installing water ballast bottom vent was a fairly easy operation. A hole had to be made on the bottom of the boat and then a plywood piece and the vent were glued on it. Purpose of the piece is to make the floor thicker as the vent thickness is more than 9 mm.
