I own a Gemini
. I recently had it hauled for bottom work and it was noted that at the angle where the flybridge joined the hulls under the boat there was a crack visible on both sides running horizontally. I instructed the yard to explore the crack and what they found was that below the barrier coat and bottom paint
was a seam sealed with what looked like a type of chaulk and what looked like screw heads apparently attaching the hulls with the flybridge. All this is below the waterline. I wonder if other Gemini
owners have had a similar experience.
