Re: Bristol 32 foward hatch support
I went ahead and bought the perko windshield adjuster and installed it in August just before my cruise to the San Juans. The thing I learned is that when the hatch is closed, it aligns perfectly. However, because of the camber of the forward hatch, as the hatch raises, the arm wants to move away from the clamp. If you take the knob off and raise the hatch with the adjuster arm pointing down you will see what I mean. That is why I broke mine. I was trying to correct for it by bending it. Zinc doesn't like that. I solved that problem mostly, by mounting a hinge to the hatch on the underside of the hatch, and then to the adjuster arm. It allows the adjuster to swing athwart ship and stay almost in alignment. I may adjust the angle of the fixed clamp knob so it aligns even better, but it works well enough now. The mid-ship hatch doesn't have as much camber so it hasn't been an issue there.
The hinge I found matched the holes perfectly. Stainless too.
