Hello,
i made a righting bar for a TheMightyHobie18.
i use my legs to keep the bar from swingging fore and aft.
there is 5' or of line tied to the end of the bar which i tie to the shroud adjuster or even better to a loop i have where the dagger board bungie attaches forward of the main beam. the "hinge" was told to me by a friend at the miami yacht club. a short piece of line tied in a square knot. i tie mine around the dolphin spike, then loop some bugie around the bar and thru the tramp lacing to keep it out of the water. first i tried just drilling a hole in a winsurfer mast tip at each end. that looked like it was cracking so i filled each end with highdensity foam plugs and wrapped the outside w/a strip of glass and epoxy at each end.
i used the bar twice successfully. the rest of the time no capsize.
this all may seem too easy but it works for me. even solo.
