The MJM 34Z is a modified deep-V hull with 18 degree deadrise at the transom continuing 11' forward and then continuous deadrise to the bow.  The hull is cored with 3/4" Corecell closed cell foam and then solid laminate on centerline, the chine flats and rails.  The laminate itself is wet pre-pregged E-glass with a Kevlar outer skin for weight savings and strength in a 60/40 glass resin ratio epoxy resin.  The entire structure is heated to 140 degrees and fully post cured crating the lightest and strongest hull structure possible.
