I recently looked at a Tartan 4700. For their hull
joints Tartan uses an aluminum
plate that is bonded to both the hull
and deck fiberglass
flanges. They then bolt right trough the flanges and the aluminum
I looked at had the hull flange in parts
separating away from the aluminum plate (only in areas without a bolt).
Apologies for the poor quality, but you can hopefully see what I mean in the middle of the attached picture.
Is this indicative of a serious issue? Is this common on Tartan hull/deck joints?
