Re: repainting a B2

I did that two years ago on mine. First step was to sand the "epoxy-proof" gelcoat Paul used down using a big Fein orbital sander, then filling in all the dings. Three layers high-build epoxy primer (by Interlux) with sanding in between, three layers or Interlux Perfection. As I didn't have a spray-...

Re: Wanted: sails for B2 with Willets mast

Lindsey Irwin made me a great set for mine with the same setup.

Happy new year!

Re: Carbon Racks

Got mine for my B2 from C-Tech. The have a tube that fits exactly into the transverse sockets of a Bieker-built B2. The quality is great, the tubes are wound prepreg.
I ended mine at the forward support. Paul advised me to leave all three supports per side in as the hull sides are built quite light.

Re: Fitting carbon racks

The wall thickness on my longitudinals is 2.2 mm, with an OD of 67.9 mm and a distance between th transverses of 1100 mm. I put an additional layer of woven carbon at places with concentrated loads (footloop holes, spin-sheet, ...)

The longitudinals are just glued to the receptacles with thickened epoxy.

I replaced my alloy racks with carbon two years ago. The best offer I got for the tubes was by C-Tech / Alex Vallings in Auckland/NZL. Typically, if you've already got carbon transverse struts, they should have moulded receptacles for the longitudinal tubes at the ends (I assume a Specialised Marine...

Das Problem ist weniger das Auge, als das auf beide Enden wechselnde Lasten draufkommen. Ein normaler Spleiss ist nur für Last auf einem Ende gedacht, bei dem "Inneren" versagt das Prinzip des Spleisses.

Splice for symmetric rig adjustment

Hi, I'm looking for a safe method for a splice like in the picture. It will be mad out of Spectra 12-strand (e.g. Dyna One), a block will be attached to the loop, both ends will have varying, potentially asymmetric loads. It has to be really secure as the shrouds will be attached to it. It would be ...

Hi Terry, I used Monel on my mast, will have to see how it stands up corrosion-wise. It might be usefull to use zinc-paste (e.g. Duralac). I thought about using stainless but wasn't sure about compliance with the other fittings (carbon is an awfully good conductor). With Monel I know which part will...

In big boats the diameter (or more precisely, cross section area) of composite rigging is usually calculated based on stretch characteristics instead of breakload. The aim is to have the same stretch as typical metallic rigging, usually resulting in a bigger safety margin on breakload. Stretch chara...

IIRC the options presented at Warnemuende were Weymouth & Portland National Sailing Academy (2012 Olymic venue) and Pornic. I think Weymouth was favourite under condition of the hosts either providing camping close to the academy or a shuttle connection from town to academy.

Well, as far as I can see, the old scupper system is still in place (pic 7). Only the bungees are missing.

Congrats Dave! It's always great to see such kind of projects getting completed. Incidentally I've got one of those Biekers that were there at Frisco (GBR1406 Mighty White). Hope to get the replacement of the racks done by the end of next week. The alloy was fizzed pretty bad. Now it's all nice blac...

What do you glue the EVA with? The manufacturer recommends neoprene or chloroprene glue, but I don't think that would work on carbon / epoxy.
