Overview of the skill:
Marking a set of moulds for a boat is an important step in the process of constructing the said ‘boat’. The origin of the information for the design of the boat will determine what has occurred before this process.
Designs can come from:
· An existing example of a boat (this is the source for this example, reviving the Mayflower class of sailing dinghies)
· Table of offsets
· Loft floor
· Lines drawing
· Computer design
· Computer cut template
Realistically, in the last two you wouldn’t make moulds from templates, you would simply get them cut from the computer mould and so removing this step.
For the Mayflower project, the design was lifted from an existing hull (see Taking the moulds of a boat), then it was lofted full size (see Lofting) and the templates were amended. Taking this information and converting it
into moulds to be used in the next step (construction of the hull) will be covered in this skill. It is a key link between the design and the final hull.
The process is demonstrated in the accompanying video clips with a step-by-step guide. The conversation with
the boat builder, in this case Marcus Lewis, is unscripted and covers the technique from his experience.
· Marking out the largest mould — mould number 3
· Updating the templates from the loft floor
· Marking out mould number 5
· Mould depth — discussion
· Cutting the moulds out
· Cut the top bars and fit to each mould
· Label each mould with number and location
