It's hard to believe that it's been a full year since we signed the contract to build Nordhavn 6837
. And a full year and a half since we decided to move forward with the project. In that time we moved off our Nordhavn 60, sold it, refined the specifications for the 68, did some travel to celebrate our 30th anniversary, and caught up on a number of other projects. Oh yes, and our 68 build started....
I never tire of seeing these boats transform from barrels of resin and bales of fiberglass into amazing boats. So let's get started. In late June 2018, the mold freed up and our boat started.
You probably thought I was kidding about barrels of resin and bales of fiberglass, but I wasn't. Here they are, ready for mixing.
|In the beginning, there was resin.|
|And there were bales of fiberglass|
The next step is the setup and preparation of the mold. The hull gets built from the outside in, with the outermost surface of the boat (the gel coat) laid up against the red surface of the mold that you can see below.
|Hull mold, currently separated to access the keel.|
Once the mold has been prepped and all the plugs are in place, the gel coat gets sprayed on forming the outermost layer of the boat. Colors always look funny in florescent light, but the hull is the standard Nordhavn light gray. All the scaffolding is suspended from above so nothing is in contact with the mold surface.
|First on is the gel coat.|
Next, the first layers of fiberglass go on. These are done with the mold halves initially separated so there is access to the deeper parts of the keel for building the finished surface. Then the halves are joined, and all the structural elements are laminated and built up.
|First finished layers of fiberglass laid in.|
Meanwhile, tanks are being built in other parts of the yard. I think these are the two water tanks.
|Water tanks, I think.|
For similar access reasons, the transom is laid up separately, then this section is joined with the rest of the mold.
Here is the hull with ever increasing lamination to build strength. Nordhavns weigh anywhere from 50% to 100% more than other similar size boats, and this is why. Strong, strong, strong.
Once the lamination is complete, a whole grid of ribbing and stringers are laminated in to add stiffness and further strength to the whole structure. In the picture below you can see forms in place, and in the next picture you can see the full structure.
Once all the ribbing is in place, all the hull bulkheads are fit and laminated into place. These add additional structural support, and help lock in the form of the hull before it is released from the mold and has to support itself.
|Bulkheads laminated in place|
A cradle is fabricated for every boat, and will stay with the boat all the way through shipping to the US
Finally, it's time to release the hull from the mold. Below is the fully assembled mold.
|Fully assembled mold|
First, the transom mold comes off exposing the hull's derriere.
|Transom section of mold removed|
The hull is then supported by overhead gantries from temporary attachment points inside the hull. Then the hull halves are separated and peeled back.
|One half separated|
And now both halves are separated.
Finally the released hull is placed in its cradle where it will live until final unloading in the US.

For some real fun, check out this video that Ta Shing made of the hull release.
Looking good TT. That is one thick hull. Are all of the 68's twins?ReplyDelete
Thanks, Bill. No, virtually all of the 68s, including ours, are single main engine plus a wing/auxiliary engine. The only twin engine that I'm aware of is Sans Soucie which is currently for sale in Seattle.ReplyDelete
Peter, great update. Just got photos of our build (Hampton Endurance 658) but your info helped pull it all together. Where the photos taken by the factory or did you go there?ReplyDelete
All the photos were provided by Ta Shing, but I'll be heading over soon to see it first hand.ReplyDelete
Good luck with her Peter, she looks good already.ReplyDelete
Curiosity: What speed is expected from the wing engine?ReplyDelete
I'm told 6 kts.Delete
I'm sure great progress has been made since this post. When is your 68 due to be launched?
Sorry I have been so delinquent on posting updates. Progress continues, but it's a long process. I have been to the yard three times so far, with the forth visit scheduled for December. At this point I expect the boat to arrive in Florida about this time next year.
