Way dodgy they cant work out what happened or where there was marginal engineering safety factor.
Does that leave the taper and socket that might have too much clearance and when sailing was relying on the fasteners?
I think I would be test fitting with 2 sheets of paper with carbon paper between them.....

I wouldn't make that assumption. I presume they investigated the crap out of it but didn't find anything they could point to as a key issue.

Neither Farr nor BP nor the builders want this to happen ever again. They surely dug in as hard as they could. This is the worst thing that could happen to the boat so if there was anything they could do to say 100% what happened and simply fix that --- even if it meant cutting that entire area of the boat and rebuild it -- they would. They would be insane not to.

The current situation is kind of the worst thing for them. The inability to point to a specific issue casts a shadow they would LOVE to get out from under.

Having said that if I was in the yacht owner class not the yacht crewing class I would order the X2. I can't wait to see it on the race course this year in the RORC races.

The harder edge race orientation really appeals to me.

It's a bit odd of how he talks about "fairing" the tenon. But that looks like fairing to me.

You'd think this would be an ideal task for CNC: machine the head to a finished shape, and the socket planted in the mold would have the same shape.

Maybe they put a coat of high density epoxy in the socket and put keel into the socket with some release film.

The yellow tape seemed uh thick for that sort of thing though. So I am unclear WTF I am seeing.

With friction fits you want a high degree of contact surface. Not big gaps anywhere.

I'd say better be honest - if you don't know - you don't know. A defect in one of the materials in the keel head (casting/laminate) or 1 non-spec bolt?

Did they ever recover the keel? I don't think so. Without the keel head to show why things failed, it's all guesses

Seems like one positive side effect is that other owners with similar setups - like the TPs, for example are making some untidy discoveries upon investigations post Hobart.

There are probably only two yards and a few nigels competent at this level, even in Sydney.

'our' Nigel's (i assume it was his) X2 was at HYS this weekend
I dont get the reverse bow on a mono
yes, you get a longer water line length, but need a longer bowsprit and more (weight) structure to support it... i am sure other will explain

I could be wrong but I always thought it was about upwash onto the jib? Thats the explanation I heard for the Kerr / Carkeek designs for example (The Kerr 46+, Ran etc), if its not I'd love someone to explain to improve my understanding 😂

I recall it being a net weight gain as well, in IMOCA and maybe the 72s. The amount of hull removed is heavier than the extra bowsprit length and reinforcement for increased leverage

Yeah, reversing the bow allows you to get a lot more chamfer in the topsides.

There is probably an element of fashion as well. Julian Everitt has Views on this on FB I am sure.

Reversed bows allow a longer waterline with
- less weight
- less windage
- fashion (just like a hard chine on heavy Beneteaus)

I'd be somewhat surprised if funneling wind into the jib that direction really works to assist the boat. Would need to see some studies to believe it.

When you are plowing through waves there is less weight of water on the deck as well, it doesn't hold as much as a normally flared boat and it sheds faster. And with proper attention the hull/deck joint can be lighter.
