    Fair enuff.

    But I still don't see the need for a custom, laser-$pecific part.

    Another solution...

    Have you ever tried sailing a Laser with no traveler blocks?? If the traveler is Spectra ( THE THICKER THE BETTER) the boom can be pulled lower to the deck and the friction is not much different than sailing with blocks. Also, the pulley does not catch on the tiller so the traveler can be pulled tighter than with a traveler block.

    I did it on a Wednesday night when a buddy broke his blocks. I knew how to make a temporary rig and swapped boats with him to do it..then the race started and I got to try his boat for an entire race. That night, medium wind, I liked the boat better without the traveler blocks.

    Reality Note: He beat me in the race and usually didn't finish ahead of me...That means I suck and only beat him the remainder of the time because my boat is better...

    Anyway..Why require blocks at all?

    My take was he was sympathizing about my getting whumped by a relatively new guy who was sailing a worse boat...I simply am not a rock star...

    sad

    I think he's sad because there are no pictures of the new blocks yet. I'm sad because of that.

    As a "rec-racer" I hope you don't mind if I add my 2 cents.

    Having taken apart a few of the existing blocks, it is obvious that anything new (particularly if it is not plastic and includes a sheave bearing) will be more expensive than what is currently legal. Therefore, it would seem to me that this would be an opportunity to take advantage of the marketplace and competition in order to keep the cost of upgrade reasonable.

    I would propose that the four blocks in question be very narrowly specified (i.e. materials and n.t.e. sizes for sheave, bearing/configuration, cheek, swallow, becket, etc.) such that more than one manufacturer could have a class legal product. Now there may be those who would argue that this would allow someone to spend a lot of money on some "high-zoot" block and therefore have some sort of unfair advantage. I know a thing or two about bearings (the real deciding factor here) and there is a law of diminishing returns such that a bearing made out of "unobtanium" will not contribute anything more to mainsheet feel, or lower resistance, etc. than one made out of Harken, Holt, etc. standard bearing material. It will remain that the more knowledgeable (and better pepared) sailor will always do well.

    Laslty, if it is not legal now, attaching the boom blocks with a swivel shackle should be allowed due to increasing numbers of sailors through-bolting the straps.

    The last thing we need are block with swiveling action, then they will be twisting all over the place.

    What we need are blocks that can be attached by clevis pins, so all you do is undo the pin, and you can take your block off. (pr any other sort of pin, shackle, ehhhhh, they need to be as close to the boom as possible. I still purpose tying them to the boom.)

    I took my new boat out for the first time today - and on my first non-light gybe the traveller block parted company with the traveller. Lovely. What was that about the old style blocks being reliable???

    A poor choice of words on my part, sorry. Having never sailed with such a thing, I could not say if it would be an enhancement, or a handicap as you suggest. My point is the removability and and use of current legal blocks. A standard shackle would rotate the block 90 degrees from the centerline of the boat. A twist shackle would solve this but the block could rotate a few degrees each way.

    Neither is desirable, the blocks do NOT want to rotate or twist, they need to stay straight. What we need is an attachment system similar to the Harken Dinghy Blocks, such as the H021, as show here, please scroll down: http://www.apsltd.com/Tree/d261000/e260621.asp

    Or the Ronstan Orbit blocks, as shown here:http://www.apsltd.com/Tree/d279000/e276355.asp These are also similar to the Harken Carbo blocks, those main benefit is that you can just tie them on. In fact, there is no need for the boom bails. But you would have to create a stop on the boom so that the blocks don't slide forward or back.... You can put the boom bails on top of boom, and tie the blocks inside of that space, or as they do in the carbon world, they add a piece of carbon fiber behind the line so it does not slide back, but we're not that advanced.

    Those Harken H021's would be a great step up, providing the same functionality but far better performance/reliability and the cost is only $10 (or thereabouts) more than the standard Laser blocks.

    They would provide a low cost, incremental improvement to the class with no modifications necessary to the boom. Not to mention the fact that you don't have to drill and re-rivet to detach/attach them.....

    Thats the whole idea. I don't know if it would be good to use those specific blocks, but if new ones are to be designed, I think it should be necessary to have an attachment system incredibly similar to those I have listed.

    A block that is tied to boom will probably twist.....

    Not if done correctly, and not any more than a standard block.

    I’m always unsure about using line to attach blocks as line does tend to wear – particularly in high load situations. Of course regular maintenance could detect and replace such wear before problems but one of the great aspects to a Laser is that it requires little maintenance.

    True

    I do not think you have to worry about using line to attach blocks to Laser booms in the near future, as we do not have the correct type of boom for the application. It would take many, many, many years for us to get that far.

    Most likely we'll end up with a new version of what we have. And if we want to put new blocks on our boom, we'll have to drill out the rivets on our boom bails, and reattach them. Knowing how well I deal with removing rivets, looks like I'll have to buy a new boom if I want the new blocks! lol
