    Spreader Geometry

    Builders of high-performance rigs definitely do "angled down"spreaders so Hall Spars (Netherlands & New Zealand) & Southern Spars (New Zealand). I guess Axxon, Lorima also have built rigs with incidence on spreaders. When it comes to aluminium, I haven't got any examples available. Also, the tip will always* (in 99%) be higher than the root of the spreader.

    Brexit, WTF

    Going with option 3... I believe "No Deal" is very expensive for EU (even if it is probably worse for UK as a whole with larger impact) and he has a duty of care towards the EU-citizens that are living in the UK. So more important than "helping May" or preventing a "good deal" for UK, I believe the focus is still very much on the very best outcome for himself (EU). I thought there was a very fair opinion peace in the guardian (about "common people" not giving very much about Brexit anymore) and in general it seems politics as a whole (not only UK, or EU, or USA) is failing to represent the electorate with focus on issues that not align with day-to-day struggles of us lot.

I actually commented on a political topic... And with an opinion. Will be interesting how this is going to work for the various shipyards in Blighty: Pendennis/Oyster/Spirit/Sunseeker/... if it all goes pear-shaped March 29, they'll get hit by 20-25% additional duties on all the gear they are importing (sails/rigs/hardware/...) --/EDIT--

    Spreader Geometry

    Curved spreaders: nothing new (but structurally a bit more challenging and fractionally longer than a straight spreader, so generally there is some weight penalty) Ran/Proteus had in-line spreaders from the start (less compression, lighter mast tube) but it reduces jib area compared to most Maxi72s with swept spreaders (also, I read in this thread 7deg sheeting angle... it is about half that), doing the curved allows for a bit more jib roach which helps when sailing in the Med against the fleet. So it always was (and always will be) a compromise. The mini650s and class40s almost all seem to have either excessively curved or even angled spreaders to allow more roach down low with the lighter straight spreaders up top. Here I am not too sure it isn't more fashion or function, but with their rules on amount of righting moment at 90deg it is a fairly easy addition. Incidence ("down angle") on spreaders is also not something new (as @mad already wrote), however between rig designers (engineers) there doesn't seem to be agreement on what the optimum angle would be (as you have to consider rake, pre-bend, max bend, heel angle, pitching moment, etcetera to find an optimum for windage). From a production standpoint it is also more expensive than installing the spreaders without incidence, especially with the spreader tip details and any antennae or lights mounted. So it will require the owner to fork out more money without a quantifiable gain. There is agreement I feel between rig engineers that incidence is -at worst- no worse than having no incidence. And once you put a radar dome on the spreader any benefit of having reduced drag from the spreader by adding 3 degrees of incidence is a complete non-issue.

    Lightning protection or no?

    The difficult part is that there is no real information regarding lightning strikes and misses. You only hear about those rigs that get struck, but there is no real information from insurance claims that can indicate what helps and what doesn't. There are roughly three options: Have your standard rig (so the wind indicator or anemometer is your highest point) Have a static electricity thingy (Forespar) (screws in to the top of the rig, no cables): light option and in theory means it makes your rig "invisible" by ensuring any static gets dissipated Have a lightning rod: copper tip and battery cable run down into the bilge and fixed to the keel bolts None of these will guarantee a safe passage or that actually your electronics will survive a strike. Some rigs that have been hit have passed NDT checks following a strike, others have failed. And as Innocent Bystander says, rig height doesn't really have any impact. Personally I haven't heard of any struck rigs with the Forespar lightning dissipator installed but then I've only seen probably a dozen of struck rigs in the past 5 years.

    Hanuman for sale

    I'd say with at least 8 guys making (well over) $2000/day, and the nipper at around $350 your average day rate is closer to $1000. Add food, drink & hotel and average crew cost is around $1500/day (Palma/Porto Cervo/St Barths ain't cheap you know). Your J is required, by rule, to have 1 tender following at all times (MOB), plus obviously you have your coach boat following as well. So that is 30 crew on the paylist for a regatta, 9 days on average per regatta and then some expenses for travel and such: you've spend well over $400k before entry fees, dockage, fuel, sails, ropes, crewgear, wear and tear... And then of course all Js are running a full time programme with designers in continuous optimisation within the class rule Basic rule of thumb still applies: 10% of original (build) price is what it takes to maintain the boat a year in a cruising configuration taking into account permanent crew cost, delivery crew, basic maintenance, dockage, fuel. A basic J (ex sails) would have set you back around $25m about 4 years ago so for $2.5m you have a nice annual budget for upkeep, insurance, permanent crew and perfectly varnished topsides. Yes Js do cross the Atlantic (motor-)sailing by themselves: cruising sails on and go. Never get below 10kts on the crossing, catch some fish on the way: its all good. As for sails... 1 main, 1 jib and a spinnaker will set you back around US$1m without doing a full optimisation study. And it doesn't include the sailties...

    who what where

    Some of the office staff (project managers, engineers) have been retained in RI as part of the service team Hall have over there. Plus there are two factories with dedicated engineers with access to the production drawings so I wouldn't be too worried. Seen a few projects over the last couple of years including a 55m+ rig where around 20mm of laminate around the partners had to be ground away on-site to remove some backing paper that was left in there... rebuild with fresh carbon, small overwrap and good to go. CF is great stuff: if you break it, you just glue it back together (slight over exaggeration there...) but I'd ask Hall in the US to supply me a new crane and bond it back in place. You might even get warranty on the repair. anyway, that is for Hall and the owner to figure out. Or check with Offshore Spars, they're still active and in the US. And US$40k sounds about right for the CF tube only, you'd still have to get all fittings across at that price and sort out shipping: materials and labour haven't become much cheaper lately.

    who what where

    You do know that Hall Spars is still building rigs right? Only have to get them from NZ or Europe (and I tried but they seem a bit busy, so expect a new rig to take more than 12 weeks...) Still got an office in RI for service so could be as easy as ordering a new carbon crane and have those guys laminate it in place. Shouldn't be more than 3 days work including cure time and re-painting once all parts are on location. Also shipping to the West Coast is generally easier from NZ than from RI

    VOR 2019-2020

    AFAIK, there is no intention of going RtW again in these 65s. From what I understand they'll use the boats (or try to..) for shorter races where there is no real competition (like the round Antartica) apart from the OD. And those events will only last until the next race is clearly defined (and thus the class is out sailing): much like people sailed IMOCAs ahead of the first VO70 event. SCA would probably need the updated rig/rigging though (add €600000 to the price) if you want to play in the OD fleet... That said, of course some people want to re-use the boats and just add DSS/Dali foils just forgetting that it basically adds righting moment and therefore all engineering on the structures becomes void so it isn't very cost effective...

    VOR 2019-2020

    Behind the scenes, plenty is being looked at to use the existing boats for some interesting events in the coming years. It requires less of a fixed team/crew so not as much interference with Olympics and AC. The "out in the open" is for instance the "Lap of Antartica", but would include some changes to the boats (different boards). It is an attempt to extend the life of these boats at minimum cost to bridge the gap without having to compete with AC and Olympics (and Vendee) for coverage.

    tp 52 crop 2018

    Carkeek. doing four 3-day events in the UK (and 1 week-long) + 1 overseas (One Ton Cup in Holland) is a lot less travelling than six 10-day events all across the Med as well as the obvious difference in cost (with the pro-am rules in place within the class for instance, as well as the limit on sails). All-in-all it should be pretty darn good bang for the buck. none of the in-build Botins are coming to the UK AFAIK

    tp 52 crop 2018

    Problem with that design is that the bow does not fit the 52 class rule... And last designer to win a race in the 52 Super Series that wasn't from Botin or JV was actually Reichel-Pugh. When building new boats for the 2015 rule, it showed that the yard has to have experience as well to ensure you're bang on target. Going to JV or Botin and having your boat built by King (VLC), Longitud Cero or Persico will mean you'll win some races and your boat will be competitive. Going RP, Mills, Farr or Carkeek and build the boat elsewhere does not mean you won't be competitive just that chances are you're off the pace in this highly developed fleet.

    what is it?

    http://www.catsailingnews.com/2017/10/tf10-sea-trials-dna-report-from.html Very few details about the dismasting itself but at least confirmation of the fact and little story about conditions.
