Again Ditto. I have the same arrangement. It allows easy attachment/detachment on the boat in a safe position in lieu of trying to secure at end of boom or at the bow. Mine also adjusts from boom.
Although I have low tech dacron, not the fancy smancy Dyneema... David F.

That way it's easy to rig a preventer to the bow when the sheets are already eased; just release the line from the end of the boom and snap it to the preventer from the bow. If running to the bow, I will usually just run the preventer through the mooring line fairlead...with appropriate chafe protection if it's going to be rigged for more than a few hours.

And when in ocean I run two preventers - port and starboard to the bow and back to cockpit winches. All lines, blocks are of stout sizing. Loads can be enormous. That way in sloppy conditions you have a "controlled " jibe. David F.

Think about the forces on the boom when the preventer stops an accidental gybe; they are not straight down, which is how the boom is strongest. The forces are more from the side (because the preventer is led forward to hold the boom in one place), which is the weakest part of the boom. Another thing to consider is that if at all possible, you should lead your preventer inside your lifelines so you don't wipe out or bend a couple of stanchions if you gybe. All that being said, it's kind of difficult to find a place near the end of the boom if you don't have a loose-footed main so the preventer will probably be attached at the mainsheet bail. I use a preventer pretty much all he time my sheets are eased, even in light stuff, a powerboat wake can cause the boom to swing into the back of a head. I wouldn't go with anything too stretchy; Dacron is fine. I usually use a single line from the boom to a block on the rail and back to a winch, so it's easy to adjust when I trim the sails.

My mainsheet sheets mid-boom. I know you need a rope with stretch to absorb shock. I was thinking of making a preventer as follows:Dyneema loop around the boom just aft of the mainsheet blocks. 3 strand nylon with snap shackles to attach to the loop and toe rail. Is that too simple? Should it run through a block to a cleat or clutch? -- Joel 35/3Annapolis 301 541 8551 _______________________________________________ This List is provided by the C&C Photo Album http://www.cncphotoalbum.com CnC-List@cnc-list.com -- Andrew Burton 61 W Narragansett Ave Newport, RI USA 02840 http://sites.google.com/site/andrewburtonyachtservices/ phone +401 965 5260 _______________________________________________ This List is provided by the C&C Photo Album http://www.cncphotoalbum.com CnC-List@cnc-list.com _______________________________________________ This List is provided by the C&C Photo Album http://www.cncphotoalbum.com CnC-List@cnc-list.com -- Andrew Burton 61 W Narragansett Ave Newport, RI USA 02840 http://sites.google.com/site/andrewburtonyachtservices/ phone +401 965 5260 _______________________________________________ This List is provided by the C&C Photo Album http://www.cncphotoalbum.com CnC-List@cnc-list.com
