John and Annie,
Look in the photo section of this site for the photo folder entitled
Amel-General. In there you'll see a posted photo "Construction
Details". In the photo (scanned from a brochure describing the Sharki-
Maramu-Mango boats) shows a cross-secion of the hull-deck joint-->a
continuously bonded lamination.
How can it be that you believe there's a need for thru bolting the DHJ?
