Oh man... This shot is spectacular!!!!

I'm going to leave the commentary about being chained up ....

Smaller portions are 12, 15 and 20 mm with a tiny bit of 25 and 30.

I am jumping out of my skin with excitement here.

I have woken up to find 25 more photos. Not just that, but the deck has been assembled. and all the bulkheads are welded on, together with the very first portion of curved hull and caprail.

Photos will follow. I'm too excited to do anything other than look at them for now .

Thats awesome scantlings for a 17 tonne yacht. Absolutely bulletproof!

The boat I ran in antarctica was substantially built from 4mm plate on about 16 tonnes loaded displacement.

I wish hull scantlings were mentioned more often as this information is just as important as the material type in describing strength and weight. It always surprises me when someone makes a statement like "metal hull give piece of mind" or "glass is not fit for high latitude" without mentioning or even knowing the scantlings.

Panope is about 7 tonnes with 3/16" (4.7mm) plate just about everywhere. I think the boat is pretty tough but certainly not as tough as many assume. I bet there are plenty of glass boats out there that are just as tough (or tougher). I'm thinking of the ones with 2 (or more) inches of solid lay-up below the waterline.

No it isn't. I have not heard of this in marine use and I am guessing this may be due to its corrosion resistance (this needs to be excellent).

Most of our construction is using 5083 single layer.

Next shot is of the starboard rear deck.

The solar arch and bollard penetrate the deck and are also welded to the interior framework. The deck adjacent to the holes has been reinforced (zoom in to see detail):

The work is impressive, the combing is flat right? It looks curved on my phone but I'm guessing it's caused by the light and marking on the aluminium or its my terrible eyes.

Thats a pretty solid little hull Steve, 5mm aluminum is amazingly tough, I saw the damage to an aluminium yacht that got caught in heavy pack ice for a few days. She was an old BOC boat, 60 foot, 4mm plate for the most part. Some huge dents but only one small hole.

My 40 footer weighs about 8t and is 6 and 5 mm underwater, 4mm above with 3mm decks. Strong enough but not massive like the Besteavear.

Yeah glass is pretty strong, but the ones I've seen go aground abrasion damage seems to quickly saw into the hull. Your video on the toughness of both materials is excellent.

There is an excellent video of a steel yacht taking massive ice damage here

I think the Besteavear would survive this, I am not so sure about my boat..

I almost stopped watching! The poor boat got the snot beat out of it and the owner had to sit and watch.

I get the allure of sailing icy water, some of the places are beautiful, pristine and pristine.

You don't happen to know what happened after all of that do you? Boat made it?

Oh, that was absolutely painful to watch!

[Seaworthy Lass]

The cockpit is now inverted again.

My heart skipped a beat seeing the first bit of hull plate attached. Even the toe rail has been added:




And the starboard side. The semicircular shape is where the engine controls will go:

[Seaworthy Lass]

Inverted cockpit looking from front to rear. All the steel supports that are used to support the inverted hull during construction are in place and the deck sheets are being positioned:

[Seaworthy Lass]

Deck in place and welded together.

Starting to look recognisable as a boat now :

Once again SWL, I'm really impressed by the rate of progress!! How many hands are involved in the actual floor construction?

The contrast to seeing our friends' alloy Samoa being built on the Clarence In Oz... they used to introduce folks to the shed by saying "here is our 75% completed aluminium yacht, now 27 months into its 14 month contracted build time... These Dutch guys are staggeringly competent.

Hi Jim
I don't know how many are working on her. I am bursting with a zillion and one questions, but don't want to badger them .

Next exciting bit in the last lot of photos was seeing the bulkheads attached.

The first and second bulkheads seemed to pop up together in the photos, so I am not sure which one came first, but this is the sequence from front to rear.
Edited to add: just looked closer and the middle bulkhead was welded on first

The front watertight bulkhead separates the forward locker from the owner's cabin. The box is the chain locker. No need to knock down any piled chain . The 3 steps on the starboard side allow access to this locker:

[Seaworthy Lass]

The second (middle) bulkhead has a watertight door. The compartments with angled openings on its forward side are the head on the port side (also containing the washing machine and holding tank) and the shower on the starboard side (with laundry tubs that will double as a showering seat). The head and shower open into the owners' cabin. The doors have been positioned to allow good air flow in the owners' cabin when the hatches are open.

On the rear side of this middle bulkhead are the galley and saloon:
