Atlanta Olympic Laser Boom Sleeved

Foredeck Shuffle

More of a Stoic Cynic, Anarchy Sounds Exhausting
I purchased a 1996 Laser a few weeks ago and have been cleaning it up and modernizing it for local racing.  It has what appears to be the correct stickers that indicates it was a boat used in the 1996 Olympics in Atlanta (sailing venue was off Savannah), it has the pretty flower pattern on the boot stripe from that year.  The history of the last two owners who make up nearly two decades of ownership is that the boat just sat with almost no use and other than the obvious UV damage to the bottom of the hull from reflections from the ground the boat is in immensely good condition.  It is dry as a bone and I put an endoscope into the boat and had a good look around, no musty salt water funk only a mild epoxy smell.

The real reason for this post is because as I was rerigging the boat for current standard gear and replacing everything plastic that is not the hull, I noticed that the boom was really heavy.  Picked up another boom from a newer Laser (2007) and it was significantly lighter.  Weighed both and the Atlanta Laser boom is 3.06kg versus the other boom at 2.28kg, both are fully rigged and have the outhaul line on them.  Figured that while the boat had not really been neglected, just not used, apparently the boom was full of mud or something at the gooseneck end.  I was going to wait to drill out fittings for when the on order Laser Harken blocks arrived but cleaning the boom out seemed a good idea.  Drilled out the rivet for the gooseneck plug, then the vang strap plate, no mud.  Took a flashlight and I see an obvious sleeve that has been mounted with the vang plate rivets.  Pop the endoscope in and the results are what you see in the linked video below.  There is no sign anywhere on the outside of the boom of any stress or other reasons for the sleeve to have been installed.  The corrosion patterns match the state of the rest of the rig.  I put this to someone that professionally treats and preserves metal for a living and they stated that without putting the boom in their lab, they could only say that it appears to all be the same age.

Was this boom used to sail in the Olympics?  How hard would it be to do this and get it on the water?  How different would this make the boom and would you need to practice sailing with the exact set up to make it worth it?  Did this boom really sail in the Olympics in this configuration?  Wonder who sailed it?

Obviously, this is all conjecture.  This boat is 26 years old and perhaps the rig is not even the same one the boat came with?  But why is there a sleeve in this boom?  As stated above, the entire rig has the same amount of galvanic corrosion on it.  All of the little yellow official Laser tag parts look the same with a similar amount of wear and aging.  Figured I would shit post this on SA before I finished re-rigging the boat, still need the new Harken blocks to finish the job anyway.

So, there you have it.  A very difficult, perhaps completely un-confirmable mystery that slings mud at the innocent and dredges up shit for the fun and amusement of the less politic end of the racing community.  Have at it and if you want me to post more photos or something relevant, feel free to ask.  I may or may not respond but will definitely be slow at answering, I have things to do.  But I have a good history with the Ed and if this drives some posts and ad banners into his bank account, so much the better.  When the Harken blocks show up, I'll drill out the rest of the rivets on the boom and dump the sleeve and post photos of that.

Well, if you are looking for controversy with this boom sleeve, you had better look elsewhere! 

The sleeve is a stiffener that as far as I know was very commonly used (not sure now as I've not sailed a Laser in some time) to keep from breaking or at least bending the boom from vang tension. I can't remember when these became standard with Lasers I purchased but I do know that when making-up a couple spare booms from broken top sections, I always added the stiffener purchased from Dick Rose at Windward Mark in Seattle. The OD of the stiffener was enough less than the ID of the boom that it took a few strips of duct tape placed on the top of the stiffener to make a nice tight fit inside the boom before pop riveting the vang key fitting onto the boom (with the pop rivets going into the sleeve).

I'm sure others here can add to the info.

Very early Laser booms were notorious for breaking in the UK. They don't now under far greater loads, so obviously the design has been changed over the years, and probably more than once. AIUI changes like this are agreed between builders, designer and the CA, the sailors aren't involved as its not a class rule change but a build manual change.

Well that's no fun.  I have an older boom from 1983 that does not weigh what this boom weighs, it is from from a boat someone hoped I could recover but the deck and hull was so spongy it ended up being cut up.

Ok, move along, nothing to see here then.  I was hoping for a really fun thread full of nonsense.

I did get a ridiculously old boat that is still mostly shiny, and apparently has a nice boom for it's day.

Thousands of the Olympic Laser with the pattern molded in were built. 
some were used in the 1996  Olympics.

The TOP SECTIONS used at Savannah WERE HEAVY.  I forget how heavy but memory says 1.2 lbs heavier than the standard top 

THE TOPS WERE REPLACED WITH STANDSRD EQUIPMENT BEFORE THE OLYMPIC FLEET WAS SOLD. 

They didn’t want broken top sections 

unfortunately, that heavy too section makes the top of the sail a lot harder to depower. 
I got one for myself thinking, as a big ox, I could deal with the extra power and go fast.

Nope!!  I went out tuning with my usual tuning friends and my boat was a dog. It didn’t matter who sailed it, he was very slow upwind inntge breeze.

I DO NOT KNOW whether the same heavy extrusion was used fir 1996 Olympic booms. 
 

The reinforcement you found is in all Laser booms built after sometime about 30 years ago.  Check the class rules. It is described.

Turn it around. Who'd want a class that doesn't fix construction flaws?
I'm all for that.  I'd like to see more changes like the C5 rigs that Julian Bethwaite designed for the Laser upgrade when it became an open conversation 4-5 years ago?

Instead we all purchased new upper sections out of carbon that you now must have because pointing improved when the MkII sail is on the carbon section.  Now the Radial has a new lower section out of carbon and sometime soon the 4.7 and Standard will get similar bottom sections.  Some day maybe even the boom will be carbon.  The boat rig will have changed and those with old rigs will not be able to compete.  But nothing at all like the sleek and powerful rigs Julian made an option that would have greatly improved Laser sailing and since we are all buying new rigs anyway, why not do it right?

Even if they were never going to be OD I would have purchased the C5 without question since I'm sailing a Laser in Portsmouth 80%+ of the time and usually travel to OD events.  I had been modifying the Squarhead sail from Intensity but they no longer make them.  Now I'm looking at modifying a rig to take a Melges 14 Gold sail.  But I'd still purchase a C5 if one were available.

If my memory is right, the Atlanta Olympic Lasers were some of the first to use "SCRIMP" or some other form of infusion.

I know of a few that were heavy to begin with and then got soft really fast.

Just, BTW, we have started selling C-Rigs again, due to demand.   We held off because Takao was well up the tree, WRT ILCA and had to let that pass along with the Olympics that he was heavily involved with, but the demand has not dropped and we have some in stock now.

Initially the demand was from the US, and now also from Asia.

All 3 version are available, if you want one, ping me.    jB

Have they received any sort of official endorsement from the class, beyond the "white sails on aluminum masts" video?
