What ever happened to USyacht?
This is a topic that comes up from time to time her and on other BB''s. From the various discussions on this and other BB''s it would appear that Bucaneers used varying degrees of chopped glass coring depending on year and model.
In one of these discussions on this topic, a fellow who actually worked at the factory described what he observed. He described that during the period that he was at the factory the hulls were laid up as follows: the molds were gelcoated. Depending on the model a layer of mat and roving was applied. Next came a chopped glass to build thickness and then depending on the model a layer of roving followed by mat (in exposed areas) or simply mat in concealed areas, was applied.
This matches what I saw in the Bucaneers that I have experienced.
He also indicated that he beleived that fairly large amounts of accelerators were used to speed final curing. This tends to make the resin more brittle over time.
