Topmast connection
« on: May 22, 2023, 01:45:09 pm »

Hi everyone.
I am scratch building from boat-line plans a Trouville/Bristol Pilot Cutter with a bread and butter carved hull, LOD 70cm, etc, approximately 1/12 scale.


This project is not a kit and information and working diagrams for the top mast connection to the lower mast are difficult to locate. Can anyone assist with information.


Cheers

These are for the Bluenose schooner, but it could be similar.
A couple of iron, or wood blocks built up, or drilled to fit the masts and brace them together.
Or a lower wood block, and lashing at the upper connection.

As an aside, typically any main stays should be connected to the lower mast. Separate stays are connected to the top mast. This is so the top mast can be lowered through the bottom bracket for both maintenance and to reduce top weight in a storm


Depending on the year, stays are also typically in pairs and the rope goes to the mast wraps around the mast, is seized together then back down to the deck. Alternate sides then sit on top of each other in turn such that the top of the lower mast is wrapped in stays. Again this facilitates removal of the top mast.


Again there can be single stays and these are known as preventer stays and are usually rigged in rough weather and reach the deck further aft to provide additional support to the mast.

You probably realise that with the main stays wrapped round the head of the lower mast it would probably be easier to sort any ratlings before fitting the upper mast.
