Building Half Hulls

An article by Octavio Oliveira

Endeavour Plans

My first half hull replica sailing boat was the famous Endeavour. I had only some information about the deck and a sight of starboard (Photo1). It was not reason to give up...

Layup Pieces

With an electric saw, I get several silhouettes and before glue them together, I painted the surfaces with a colourwashing (Photo2).

The images of photos 3 to 5 show the utility of this trick, giving nice accentuating longitudinal lines on the model, do not forget the MDF has no veins, it is an homogeneous pulp of sawdust!

I choose a much known method usual in models 50 or more centimetres length (name of this old technology---bread with cheese, strange indeed…) .The rudder in this case was built as an independent piece.

It was a challenge to improve, I tried Portuguese old boats, very typical indeed. Photos 6, 7.

The revue Wooden Boats

The revue Wooden Boats give me a chance to study some reduced plans. Photo 15.

To carve half models was begun a long time ago. A customer orders a new ship, the first thing made for the master carpenter in shipyard was a half hull in the wood of future vessel…

Antique HalfHull

After some corrections, this “tool” was the source of the plans to construct the boat. Why not to conserve this nice object as a souvenir, generation after generation of owners? Photo 16

A model like that in an antiques shop.

Some examples of my work.

Why appeared this competition? And arrived till our days, very actual and important in the World Sail?

At the end of XIX century a Universal Exhibition in London, honours the splendour of Great England. The Americans do not want to stay behind, they have something too … one pilot boat named “America” a project of Georges Steers not finished yet in William Brown’s dockyard.

The Count of Wilton, commodore of Royal Yacht Squadron in Great Britain, wishes to see this ship participate in the Cowes’ regatta in August of 1851, in presence of the England Queen …

Worst than invitation, it was a duel. The defeat of “America” will be a shame to the New Country.

In the early morning of 22 August, 17 ships will be fight for the victory in a course of 53 miles. At the signal of departure and after some incidents the glorious “ America” take the advantage left behind it… some miles…the English fleet.

Precisely, at 20.37 hours, a cannon shot salutes the triumph of this extraordinary tall ship.

In the same day, the Count of Wilton (not very happy…) gives one trophy, to Jonh Cox Stevens, a Cup of 60 centimetres high, weighing 4,168 grams of silver, nicely sculpted style “rococo”. Photo28.
