Narrative

This document contains….

  1. Our technical mizzen mast calculations.
  2. Mast shed and mizzen mast operations in photos.

 

We needed space for the spars. We rented the motorbike parking lot, made a deal with Khun Phithak, the shipyard owner, 50/50 on the roof cost. The add-on roof is 30 metres long x 7 metres wide x 6 metres high. Australian mast builder Juha Yli-Rami made the structure operational with Cariad labour. Three-Phase and Single-Phase power was fitted in way of machines. Juha was previously responsible for building all the spars in 2007-2008. He started his career as a pattern maker hence his wood working tolerances are precise, then spent the next 30 years building boats.

 

Calculations & 3D drawings.

The Undersigned and Capt. Luigi Garguilo worked as Associates for eleven years. Luigi was a naval architect and rigging specialist. For two years 2006-2008 we worked on technical aspects of Cariad’s rig and stability characteristics. Some of those calculations are included in this submission. Luigi died of a heart attack in 2017. He was a key player in the previous Cariad restoration, but his calculations live on.
