Had almost this same incidence happen with my wife as crew...
Sliding face first down the tramp her hook caught the center tramp lacing and within seconds she was two feet under water, attached to the tramp... Thank God we had the circa 1980, quick release hook. Does any one remember what I'm talking about? Looks identical to the small (not spreader bar) type harness buckle, but had a short line tail to actuate a spring loaded release mechanism (the whole hook and backing plate slid out of the frame). This saved her life. Diving down under the water, against the bouyancy of the life vest was difficult enough, not leaving me much time to do anything other than pull that cord and yank her out from under the boat and to the surface.
Was there some suspected defect to these? Back into cat sailing/racing after several years off I notice they're not available any longer (at least not in the Hobie catalogue). I have some older style harnesses I'd like to outfit them with. Are they still available somewhere?
We believe in quick release.
Flatlander18, I believe you're talking about the excellent Matson QR (quick-release) buckle. Not sure why they are no longer made... probably some @!*& lawyers involved. I know of no design defects, and mine has never let go when I didn't want it to. I have simulated "rescuing" myself with it under loads exceeding my body weight, and it releases nicely. I also like the plastic retainer which keeps you from coming unhooked when slack, and will retain the hook in an emergency release.
Mine is holding up well and you can't have it. ;') The new replacement (from a different mfr.) in the Murray's catalog looks to be weaker, less failsafe, and (*ta-DAH*) FOUR times the cost! Is that "progress"???
