Golly, not that joint again!
Joe'
Admiral Bill is the one to ask. It would be good to have the official Pearson specs in a schematic form for this magical joint!
You may have read my objections to it in the text on these pages. It is a butt joint (NO FLANGES) with layers of matt holding the join together. There are obvious thickness differences over the years of production. But it is a mindlessly simple feat of engineering to say the least.
This miracle joint has evidently held the A/Cs together for nearly half a century! So far as I know no Ariel deck has separated from the hull in any shape or form!
I don't believe that any production boat (of course I don't know how other models of Pearson/Alberg hull/deck connections were made) has a simpler connect. Makes me wonder if all the doodah of bolts and turns and flanges and 5200 is really necessary. Except to keep the water out....which was not thought out very well on my Little Gull because the screws for the 1/2" 'rubbing strake' aka stainless steel trim were driven right into the seam causing a number of leaks. Things have radically changed.
338s actual hull and deck connect is little more than 1/8" to 3/16" actual laminate meeting edge to edge
with a varying thickness of polyester matt tabbing that in some places made the join around 3/8" thick.
You have to assume that this is a 'cold' joint as the deck and hull had to be existing befor they were glued, RIGHT? Polyester is not a glue!
