Chris, do you have any hard numbers for the weight variations of the S&S 34s, say Boomaroo or bluebell vs Crux.
I would bet the range was well over 1200kg.
Also interesting from the pics of different boats would be the aft freeboard's.

Crux.

Interestingly these last 3 boats had the option of putting the engine back in the saloon. Looking at the photos it looks like Crux has the engine under the bridge deck.

I've only got numbers from the more racing oriented ones that have had an IRC rating semi recently, however:
Crux/Blondie: 5069kg
Huckleberry: 4748kg
Swagman: 5150lg
Le Jag: 5275kg
Soon: 5325kg
Perie Banou III: 4950kg

Azzurro is apparently around 4800kg (which is kinda heavy when you consider it has basically no interior, yet Huckleberry does). Apparently the original Perie Banou was around 4500kg and had a stripped out interior, although thats only from what i've been told by Jon.

Some were built with thicker layups by the original owners, some have foam core decks and obviously no two have the same interor fitout. So yeah, lots of variance. More cruising oriented ones could be upwards of 5500kg+

Some of the weight differences in the keels. The later boats keels were a couple of hundred kilos lighter! The Aquafiber built SS34's were 4,100 kg with a full fit out!

According to this page the boats after 2004 are 25% lighter than the original Swarbicks.
sailboat.guide/ss-34

The scales dont lie, the new build are not 25% lighter total. It's a bit of marketing. The hull is 25% lighter but the hull itself is probably only about a quater of the total weight, so in reality, the new builds are only a few hundred kgs lighter. The hulls are much stiffer and stronger though.

Huckleberry has a wafer thin layup on the cabin sides. I can flex it with my hands, whereas Perie Banou III's is twice as thick. But then PB3 has a foam cored deck. Swagman has a lot more glass running along the centerline, and so on. There's all sorts of weird quirks with the construction.

The mk2 keel is a bit lighter than the mk1 on account of the deeper draught. I've seen a few ORCi certs from the UK boats, they aint anywhere near 4100kg. I don't think any 34 got near the original design displacement.

Morning Cloud's displacement is 13,000 pounds! About the only comment to be made about SS34's are they are all different. Even Swarbrick built ones.

Yes, totally irrelevant comparison. How many have circumnavigated in them?

Totally relevant comparison as the question pertained to the Sydney to Hobart. She's done 2.

Footage from Crux last month in Sydney to Hobart, 16.4kts peak speed

That's great helming, but those bow waves...ugh. The loads on the rigging, the poor thing. What a displacement hull looks like bludgeoning a few ton of water out of the way as its skulldragged through the water .

It's gravity and pushing from the water at the rear that is doing most of the work. The main sheet is fairly slack a lot of the time and particularly while surfing downhill so maybe the forces on the rig aren't that bad.

If the forces were all from the rig the yacht would probably be burying it's bow and becoming very hard to control before it went that fast.

Perhaps his mate isn't asleep but is running backwards and forwards in the cabin to stay on the waves :-).

Good point that. On an modded Swarbrick 42 the fastest speed we did in Bass Strait was all surfs, and that was purely because we were falling down near-vertical wave fronts more than sail power. The sails would be flapping and completely depowered in the troughs then almost blow out every time you crested a wave. The boat was pinned on its ear on the crest and upright and wallowing in the trough, horrible to helm in.

Too funny
if reported correctly there is a measurement there is measurement controversy between the s&s 34 s
azzurro has requested a remeasurement of crux
