I've tried to find an answer without consulting the gurus here but alas, Hi gurus. I have some otherwise nice twin sheet genoa blocks on my 1 1/4 track but they have a serious problem of always laying down so that my genoa sheets ride on the metal housing and not on the block. It puts my sheet at a sharp angle over a sharp edge and is no good whatsoever.

I see that my blocks, like all of them, are supposed to pivot from side to side, and yet mine lay all the way down and this allows the sheet to ride on the housing instead of pulling up the block.

My question is this: I see on the sides of my blocks that there are holes, as though there should be a rubber stopper or support of some type that would solve this problem nicely. No where on the unit does it state manufacturer. Does anyone out there have a similar block and know where I could find these rubber supports?

Sorry, I don't have a picture yet.

Thanks!

Somewhere Alex (Guiletta) has posted on how to make a perfectly acceptable stand-up block using a tennis ball. He even included drawings.
It may be on Anything-Sailing. Can't remember. It seemed like a pretty cool idea though.

Thanks so much for the link. I'd seen that before but forgotten about it. I'm not sure how I could use tennis balls to hold up my track block, but maybe. I still have to think these blocks were originally built to stand up pretty well, and that over time the rubber just wore out and the PO threw it away. I just need to find, or make, the rubber piece to fit the hole that's already there. I've googled rubber for track blocks and you don't want to know what I came up with!

Not sure I had the exact same problem, but I've made some jib sheet fairlead blocks stand up by tightly wrapping a piece of bicycle inner tube around the base, under the block, and then tieing it off with cable ties.
If you need a photo, please let me know.

That's a clever idea that I can see working well. I wonder how the inner tube stands up to UV? How long have you had this in place and under what sort of conditions? A picture would be great.

Man I love Google. I searched UV resistance of bicycle tubes and came up with this: UV resistance of silicone rubber compared with that of other elastomers
which explains why the stuff resists UV well. I even got to practice my old organic chemistry skills from college!

If no one has better information I'll try the tubes, as they are at least a good stop gap. May look bad, but then again I try to keep her ugly so as not to distract from my wife's beauty. Don't want any more competition for my affections...

The tennis ball idea that Gui has posted about should work fairly well, even on a block on track, provided the ball sits on the car properly.

I'm going down to Aeolus today and will take a close look at whether I think a tennis ball approach or one of the other good ideas will work best. Thanks for the link to that performance sailing site, it was new to me. None of that stuff would fit my blocks however.

I just received some new track car single blocks from Garhauer that I'm going to use to create a fair lead to my winches. I have to do some surgery to add these new cars as the end track bolts of course are meant to keep stuff from sliding off. Getting to the head of these bolts on a Gulf 32 requires the removal of some paneling and stuff, but not too bad. These new blocks look great!

I'll try to remember to post a picture of whatever solution I end up with, and thanks as always for the help.

Sorry it took so long to post the pix - had to take it first.
This is season #5 for the inner tube.
Pretty, it ain't, but it sure works!

AE28,
That's awesome. Great shot, great idea. I went and checked my block and think I could possibly get the tennis ball or tube to work. Of course the twin sheet block is a different arrangement than your stand up block, but it would probably work.

Today I think I'll start to remove my T-track so I can slide on my new fairlead car blocks, and will bring a tennis ball and some old tube to try out both.

I took a bunch of my wife's family out sailing this week and most of them had only had traumatic experiences sailing with bad sailors in SF Bay in typically harsh conditions. Had 15 knots and a perfect sail, other than this damn twin sheet block continuing to lay down and force my genoa sheet to ride over the sharp edge of the stainless steel frame. They didn't know it was possible to sail fast and happily without fear and screaming. It's so nice to give people positive experiences on boats.

Photo of genoa block

Here is a photo of my T-track with the genoa twin sheet block I've been discussing. I installed my single stand up fairlead block aft of it today, so I can get a fairlead to my winch regardless of the position of my main sheet block. You can see here how the genoa block lays over on its side and the sheet rides on the frame. It doesn't look too bad here, but when the sail is raised, the angle to the block is more acute and the problem even greater.

Couple of (probably) stupid suggestions you've undoubtedly already tried:
reverse the fore and aft positions of the two leads and/or turn the grey lead 180 degrees so it tilts inboard rather than outboard.
:)

Problem solved

Thanks to everyone for advice and encouragement. I've gone with the inner tube solution for now and it is working well. In this picture the inner tube is a little higher on the block than it is now. I moved it down a little to not rub the sheet.

Between the new Garhauer stand up block fairlead, and this ability to keep the twin sheet genoa block from flopping over on its side, I feel like I have seriously upgraded the functionality and durability of my headsail system.

Sailed today in decent wind and everything worked great. For the first time ever, I could move my forward block forward for broad reaching and then back for close reaching without rerouting the sheet to the winch, or constantly adjusting the block to keep the sheet on the roller and not the housing. Hooray!
