Here's the mast base core. This chunk will be fully encapsulated with epoxy and multiple layers of glass. I elected to laminate this piece from White Oak. White Oak is known for it's durability and resistance to water. ( White Oaks have cellular structures called tyloses. Tyloses give the wood a closed cellular structure, which does not allow water to pass.) further knowledge on White Oak: http://en.wikipedia.org/wiki/Quercus_alba
To further reduce ANY possibility of water intrusion, all fastener penetrations will first be drilled out oversize with a large paddle bit then the void will be filled with solid epoxy, micro, aero fill so that any fasteners will have no contact with the wood.
