1.What type of core material are you using?  Corecell?
2.Epoxy resin?  Or vinylester/polyester?
3.The bow profile looks different than the original trawlercats
from what I recall.  Yours has almost a wave piercing protrusion.  Was
that a design modification?  What's its purpose - to reduce pitching?

The core material varies on location.  The topside is Diab H80 with
vinylester while the bottom is Corecell H100 with vinylester as a primary
application and an epoxy for the sheathing layer.

You are correct that the bow design has changed dramatically.  For one thing
the LWL was increased from 37' 7" to 43' 7" by adding the z-bow (or
wave-piercing bulbous bow if you will).  The bow concept was tried and
proved in the catamaran ferry business to reduce a vessels motion in rough
water by using hulls that had a minimum of buoyancy above the waterline
forward. The idea was that these hulls would cut through the waves and not
lift to a wave thereby reducing the vertical motion of the bows.  I just
added a photo that will give a better view of the bow, although it is still
upside down.

You are also right that excitement is mounting.  Christmas should come in
May.
