      Abbreviated rules   07/28/2017

      Underdawg did an excellent job of explaining the rules.  Here's the simplified version: Don't insinuate Pedo.  Warning and or timeout for a first offense.  PermaFlick for any subsequent offenses Don't out members.  See above for penalties.  Caveat:  if you have ever used your own real name or personal information here on the forums since, like, ever - it doesn't count and you are fair game. If you see spam posts, report it to the mods.  We do not hang out in every thread 24/7 If you see any of the above, report it to the mods by hitting the Report button in the offending post.   We do not take action for foul language, off-subject content, or abusive behavior unless it escalates to persistent stalking.  There may be times that we might warn someone or flick someone for something particularly egregious.  There is no standard, we will know it when we see it.  If you continually report things that do not fall into rules #1 or 2 above, you may very well get a timeout yourself for annoying the Mods with repeated whining.  Use your best judgement. Warnings, timeouts, suspensions and flicks are arbitrary and capricious.  Deal with it.  Welcome to anarchy.   If you are a newbie, there are unwritten rules to adhere to.  They will be explained to you soon enough.

Storm Sail Mast Mounting Question

Recommended Posts

My carbon mast has very little room aft, probably not enough, on either side of the Harken track and Antal cars to mount a dedicated storm sail track. Furthermore, the main can only be removed by removing four machine screws in a 12" section of the track which is flat out impossible in a blow. That section of track is located just above the headboard, which is still 7' above deck.

 

I need storm sails. I see many offshore race boats without dedicated tracks. How do they do this?

Will the Harken Trysail Switch System not work on your mast?

 

It might. Until now, I didn't realize that its trysail track is designed to bend around to the side of the mast:

 

SHARES TRACK WITH SWITCH T-TRACK BATTCAR SYSTEM

Pewaukee, WI—Harken's new Trysail switch system integrates with its innovative Switch T-Track Battcar System by sharing a single mast track to reduce weight aloft. Dedicated trysail cars enter the system from the loading track mounted to the side of the mast. The cars bypass the mainsail switch and enter the mainsail T-Track via the trysail switch mounted above the gate track.

 

“These new cars and switch take advantage of the innovative Switch T-Track Battcar design to reduce weight aloft by eliminating separate trysail track,” said lead engineer Steve Orlebeke. “It utilizes the switch function to allow the trysail to go from an extra track next to the mainsail track near the boom and onto the single mast track above the mainsail.”

 

Both trysail and mainsail systems are available in 26, 32, and 50 mm sizes. Cars are deep-saturation Hardkote-anodized with PTFE impregnation for durability and low friction. Track is also Hardkote-anodized. The switch plate has no moving parts.

If you've got Antal Cars, it is likely you have Antal track, not Harken

Does harken make anything like the antal gate for loading cars partway up a mainsail track? That would be the thing to use. Drop the main totally and then feed the trysail cars on above it...

 

Edit: if he has antal track then find one of these gates for the boat. They don't take up any extra space on the mast.

If I recall correctly, you need a seperate track to satisfy the ORR regs.

 

Sail Safe!

ORC Regs 4.26.4j

"

 

j) A trysail track should allow for the trysail to be hoisted quickly when the mainsail is lowered whether or not the mainsail is stowed on the main boom.

 

"

No mention of separate track, just the ability to do it quickly and with the mainsail down totally.

I would rather not put any more holes in the rig.

 

Ditto. Nor do I have much room on the aft side. As an aside, in looking at the Harken system, I like the gating option that lowers the height of the stacked main. As is, I can't installl my main halyard or sail cover without climbing up the mast. I do have Antal cars so will check into their comparable options

 

I'm quite certain that many boats race the occassional Cat-1 without a dedicated track. For light use, one option is to remove the headboard, attach the trysail to its car and add a few spare cars below it.

Hi Mung,

 

No pretty way to do this job for sure, but if I had to do it myself I'd think about using G10 tube. I'd pick a size able to handle 1/2" slug after the tube was cut in half. Cut the tube in half and lay it up on a thin section of G10 slightly wider than the tube and fillet the tube to the strip. Then carve out a groove for the slugs and stick it to the mast with Plexus. Obviously you want to run this down to the deck so the Storm Try can sit there ready to go, so forming the piece to make the required bends could be a head scratcher, but not rocket science...With a little putty and paint it might even look OK...

 

I'll build you one if you want. How much money you got?

 

Cheers,

Rob

I don't know know if this has been mentioned byt one easy way is to just leave the cars on the mast between the headboard car and the first car on the mainsail. Sure they get hosted up so you are probably adding an extra few ounces at the top of the rig, but it makes getting a storm tri on very easy. You drop the main, pop the headboard off its car and put the tri on the spare cars. You don't even have to use the headboard car, just make sure the top car for the tri is attached to it.
