Congratulations!  
A smile like a split watermelon.  
Thanks for taking us on the build journey.  Very interesting to follow the challenges of your thought process.  I look forward to doing something similar soon.  
Well done and enjoy the ride.

10.5 kts under main only?

I’m not surprised at all.

We were two up on the 12.50 reaching into confined waters in a building breeze , white sails only and bagged out averaging low teens. 
Too lazy and tired to reef so we just dropped the main and ran under the genoa. The boat speed never dropped below 10 till we ran out of sea room and furled it away.

Dang this is one mighty looking build.  A couple of questions … maybe Shaggy can speak from experience and might be relevant to your build Tumbleweed:

  • How is the pivot keel and the inside of the keel housing anti-fouled?  How easy is re-anti-fouling?  Can it be done in situ, or is it a case of dropping the keel out , anti-fouling it and inside the housing and reinstalling it?
  • Is the keel earthed?  Is there any lightning earth strap from mast to keel?  Is there a lightning rod at masthead and an earthing strap running down the inside of the mast?  I've seen horrifying photos of carbon masts reduced to carbon dust by a lightning strike. Or do you just rely on insurance and hope for the best?  :(

Cheers and keep that build chugging along for all us voyeurs … thanks

Been wondering myself about anti fouling with this type of keel- there are more and more of them…

and kudos!  Kewl boat!

The more common flat fiberglass battens have a range, in terms of stiffness, that is related to their thickness.  In the various manufacturers' specs, they quote a range of stiffness that they could be expected to offer, and the requirements for this main sail were on the max end of that range for their thickest available battens.  I can't remember if that was the case for the gaff batten holding up the corner of the square top, or for the longest batten, but one of those two were really iffy.  

They C-tech are carbon, with an oval cross section. They offer higher ranges of stiffness, for a lighter product   Since I just dropped some $$$ on a high modulus carbon mast, spreaders, and titanium fittings, it seemed like a no brainer to minimize weight aloft, especially since they weren't all that expensive relative to the mast upgrades.  

I don't think they taper into a flat shape towards the luff, but I'll know for sure once they show up!

It’s when they do the S bend around the shrouds that things get interesting.

And here's a video of the first sea trial

Holy smokes that thing is awesome. I still can't get over the stern, love it.

The big diameter "drum" makes furling so much easier. In general I find furling systems are way ahead of themselves in terms of safe working load to drum diameter ratio. Some of these systems that can handle 4-6 tons have such small drums that if you put them on a boat that can generate those kind of loads you'll seriously struggle to furl the sail.

Thank you again for sharing, hope to see more videos!

Hi Tumbleweed congratulations on the new boat. I have been dreaming of a pogo 50 for a while.

What are your thoughts on the larger rig now that you have sailed with it a bit.

Forecast for the first passage, across the Bay of Biscay is looking outrageously good.  I setup a website svpommesfrites.com. Sign up to my email list for updates/pics/vids as we do this crossing.

Thanks for the update Tumbleweed, that weather window looks like it has 'Pogo' stamped on it.

Have you had a chance to test out  your reaching sailplan? This is going to be an awesome shakedown sail.
