Title: Orkney ferry Graemsay being lengthened
Post by: DavieTait on November 02, 2009, 10:01:37 pm
Dave Metcalf used to do a kit of her but anyone wanting a challenge could cut her in half and lengthen her as is being done just now up at MacDuff harbour

Interesting photos, Davie.  A lengthened Metcalf Mouldings 'Graesmay' would make an interesting project.  :-))

Hi Davie

What is the actual reason for lengthen her, rather than buy another bigger boat. Cost ??

Hope I don't upset anyone but I think she might look better when a bit longer. Interesting photos.

Once the designers have done their bit, do they just literally take a disk cutter or torch to it?

Thats right Martin the normally make the cut on a bulkhead if they can. On fishing boats its sometimes cut on a Z shape to try and make the transition of the shearline less abrupt.

Are some boats designed with the option to lengthen them in the original design then?

There's been a few fishing boats built over the last 10-15 years that were designed to be lengthened Martin. With the new designs having an almost parallel mid-section its easier to do than with previous designs.

In the latest issue (44) of "Ships In Focus" there is a short item that explains why cutting a ship in two and inserting a lengthening section is a naval architects nightmare.
Do many (any) of you subscribe to this journal? If not, then I would be in seventh heaven if I went on the "What Ship" thingy. BY.

4.5m longer so should be able to carry 2 more cars than before.

from news reports over the last couple of weeks it looks like the bulk of the Orkney fleet is approaching 20 years old and in need of replacing , this lengthening must be a way of extending the life of the ferry and making her more able to carry different cargoes

Bryan, "Ships in Focus" is by far the best journal published about ships and shipping companies. The books that the "Ships in Focus" team, led by John Clarkson, also publish on shipping company histories make great reading with many superb photographs.
