New Zealand scow centreboard

(1/2) > >>

Popeye:
I'm currently building a New Zealand scow but have no idea how the centreboard was hung and raised /lowered.
Can anyone out there in Mayhemland shed any light on the subject, eg., drawings, sketches, photos etc.?

Thanks in anticipation of a positive response

Antipodean:

I managed to find this. Page 4 has a diagram showing the centreboard down which says to me it lowers and raises vertically using a manual or mechanical system. Page 39 has the instructions for raising and lowering the centreboard.

This page has a gallery showing the restoration of the Jane Gifford and the centreboard is shown raised in a few photos.

I agree with Popeye.
The centerboard is in a box from deck (or even locker height) to keel.
Raised and lowered mechanically, it only mentions one winch handle and I am guessing it has a gearbox.
In one of the photos from the second link, there also appears to be a runner (like a drawer runner) in the middle of the face of the centerboard (see pic). If I am correct, this would keep centerboard vertical and stop it from sticking when being raised or lowered.
Alternatively it could be a rack, for a rack and pinion lifting gear.

There are also plans available, which may or may not help. https://www.cornwallmodelboats.co.uk/acatalog/mar2492.html

Hi Popeye,
I seem to recall that the Auckland Maritime Museum has a restored scow that does day trips.
You may be able to get some information from them.
