222 Tension bar 3 If there is any give to your cabin roof due to the pressure of the shrouds bearing down on the mast, you may discover that your shrouds are getting loose. I truly believe that this problem can be avoided altogether by installing a strut similar to this one. This strut was installed at the Fall River Ma., O'Day factory in 1986 when they built my boat.
DSC00450 This is a mast crutch attachment that I had made up for me years ago by a marine metal fabricator. I made the wooden crutch and later install a small roller in it. The weight of the mast is being supported by the 90 degree 1" base fitting which is screwed to the cockpit sole just in front of the self bailing well.
Tension bar sketch 001 These angles are pretty close to the ones on my bar. What I would do is try to mock up a bar out of wood for instances and check to see how it fits. Then take it to a welder and have him make you up one similar to it out of 1" stainless steel pipe.
scan0001 Before you construct one of these, get a measurement of your mast tabernacle bolt spacing. Then figure on the size plate needed to accommodate that spacing for you holes.

222 Tension bar 2 This strut is just a 1" stainless steel pipe with a flat spot on one end with two holes in it for bolting to the galley cabinet post. The other end has a welded flange with two holes for attaching to the mast tabernacle bolts. The bolt spacing on the welded flange might be different depending on what make mast and tabernacle is on the boat. My boat came with Z-Difusion (Z-Spar) internal halyards and I suspect that the tabernacle plate on the cabin may have a different bolt spacing than an O'Day 222 with Dwyer spars.
222 Tension bar 1This tension bar is not a mod but I felt that it should be in this album because earlier O'Day 222 models particularly the 1984s didn't come with this tension bar for some unknown reason. It would behoove the owner to try and have one made and installed. I think it is very important.
Finished extrusion 002 This is the finished extrusion. Well,-almost finished. I later added two more bolts to it. What you see is a Trex plug that fits into the mast and it's sitting on a 1/4" Aluminum plate with two pieces of PVC trim board bolted to the top tabernacle plate. I cut some kerfs on the edge of the Trex where it fits into the mast. Hopefully, any water that gets in the mast will drain right out through these kerfs. I don't know if anyone out there has ever done this. Maybe I'm the first. All I can tell you is, so far it's worked out fine.
