Air is still 'cool & crisp', but sun came out Friday so I finally installed Righting Pole to our 21 SC
Key to the whole design was suggestion of Forum regular Steve Pesce to use a Chinook windsurfing mechanical universal-joint so the Righting Pole folds up flush to the trampoline underside and out of the way! http://www.violaphoto.com/hobie21-righting-pole.htm
This righting pole came with the boat .. believe it to be a "Rick White Power Righting System"http://www.catsailor.com/power_righter.html
and appears to tie to the dolpin striker with a bunch of hatchet knots
Prior to final installation, I used Zinc primer on the aluminum 'mounting plate' and then applied an 'orange' enamel final coat. The plate's "V" was cut/filed to fit up snug to the dolphin-striker stainless nut, as well as on 'top' of the stainless washer. Stainless 1/4" washers were placed at each rivet hole (all lubricated with never-seize) to level the mounting plate on the crossbar.
5/16" nylon lines run from end of the Righting Pole through Harken bullet blocks at each corner of the crossbar (already on the dolphin striker bar), and then back through Harken pivot Cam blocks (riveted to righting pole 24" from its base). Reckoned use of Cam blocks (-vs- knots) would be easier to adjust Righting Pole 'angle' to hulls (60-70 degrees to upright hull) when righting boat, as well as for re-stowing to get back underway.
Ends of the righting-line now go back to the bullet block mounts.
The Righting Pole is just over 7 ft long, so it does not reach the rear cross-bar. However, a 3/8" bungee loop comes out of the nylon end cap
so I was able to secure the Righting Pole end with a 1/4" nylon line & ss clip to the rear crossbar.
It's time to FLY!
