Jefa Marine produces a wide range of standard rudder blades for boats from 22 to 75 feet length. This unique product line offers the boat builder a modern rudder blade without investing in expensive molds. The rudders are made in our modern GRP factory and are available in many sizes depending on the boat size. What makes the Jefa rudder blades unique and distinct from all other rudder blade producers and yard made rudder blades is the production in solid aluminium molds. This unique production method allows very high pressures to be used in the gluing and foaming process and results in an extremely precise end shape. Traditional glass fiber molds don’t allow any pressure from inside the blade, so one can’t be sure of a good bonding of both sides and the final shape of the rudder.
