MUMMP:
Interesting observation,I did not notice that while in the inspection phase, before purchase.
While in the disassemble phase I noticed that both beams were identical. I attributed that to simpler/cheaper for the manufacturer, they could buy lengths of only one extrusion & cut them into sections. I thought perhaps the front beam was stronger, to hold the mast loads + tramp, while the rear might be a thicker wall to accept the traveller screws. They are identical beams.
I believe they came from the factory this. A very close examination after removing them showed two faint lines on only a portion of each end, corresponding to the location of the straps. I think it unlikely that changing them would have resulted in replacing the straps on the exact same position, I should see two sets of markings.
Do you have any info, pictures on what a truly original rear beam for a 5.7 looks like? To your knowledge what is the difference?

I do have pictures but I'm a retard when it comes to posting without hosting the image.
The earlier rear extrusions had a traveler track bolted on. The newer rear extrusions had the track extruded into the form, which covered the entire length of the beam. A slot was machined into beam to allow the straps to be mounted. These newer extrusions were considerably lighter. I had them both ways and very much liked the all aluminum track included extrusion version.
I don't believe Nacra would build a boat this way. What probably happened is a previous owner ordered a replacement beam and this was sent in error or discounted, etc. . . . or he found one from someone/somewhere and made it work. I'll see if I have a picture in my album here.
Beam Straps. They do fail. It has happened to me twice, and while sailing. Keep an eye on them. Look for fatigue where the bend is in relationship to the strap castings.

MUMMP:
Thnx for the heads up regarding the straps. My 5.7 is an '84, I think this was before they extruded the traveler track, it is definitely screwed on.
I saved a couple of your pics, thye will be useful when it comes time to rig trapezes.
The pic titled "crystal clear water", what is the line that is shackled to the bottom of the DS rod? I can't quite make out if it ends at the mast, or goes into the tramp pocket. Is it some sort of mast safety line, or the righting line?
Thanks.

Stupid me, that is exactly what I did. I just didn't see the images, so I went back and edited by removing the [img] and then adding the links.
BTW, there is one picture embedded there now, who did that?

That is a rarely used righting line, just there for looks. ;)

Awesome, thanks.
Somehow in the last 10 years I lost my grease gun. Not sure how to lose something like that, but I guess if you don't look for it for 10 years that can happen..
