Norsand's Yard at Whangarei does not use a modern Travelift (a modified seacontainer travelling crane, with lifting staps which go under the hull), but rather the old-fashioned method of having the boat float onto a steel cradle lowered down a slipway at high tide, then pulled up by a chain. This is ideal for catamarans and trimarans, and really heavy boats which can utilise a marine railway set into the slipway. But it's slow - at most two boats per tide.
We'd never used this method before, so it was a novel experience - especially since we were right on the maximum draft that the Yard could handle. This meant that we had to come out at the height of a Spring tide, and can only go back in on one or two days per month.
 
So here we are coming out:
 
 
We have been floated over the cradle and have been pulled up half a metre out of the water to check that everything is properly positioned before the full weight comes on the keel. Ali can be seen on the left, dealing with all the tension and excitement by having a nice calming gossip on the phone.
 
And here is the 'puller' - a tractor attached to a hauser and chain. You can also see the rails set into the slipway, but our trailer was on ordinary wheels:
 
 
Now we're a bit further out with the weight on the keel and the sides supported by four vertical steel arms:
 
 
And finally, after an hour or so, we're on dry land:
 
 
The process requires three people, and is very slow compared to a Travelift - but it's much safer (you can't drop the boat, which happens!) and much gentler. We prefer it. And you end up in a very strong stable cradle with loads of room to work, instead of being surrounded by a small forest of props.
