There is an excellent plan to set up the jig from the US-CNC-Kit supplier B&B Yachtdesign. However, it is important to think about some details before setting up the jig. This will save you time-consuming doublework. I put many ideas from my colleagues who have already completed these steps during their build into my concept.

The first thing I needed was a underlayer foil to protect the floor from dirt. A laser-level is a must have. It’s also worth thinking about how you want to turn the hull later and maybe you need later support rollers to move the jig / hull.

I bought 6 meter long spruce / fir squared timber and at the same time Siberian larch in 6 meter length for the stringers. In order to protect the workshop floor, I lay a thin cardboard to the floor and fixed it with tape. Then I installed the workbench at the head end. I attached the laser level at the hight of the waterline  to the workbench. So I have a fixed reference point and can check the symmetry of the construction at any time.

To strengthen the jig I installed some struts to make it torsion-resistant. I checked repeatedly all dimensions with the laser and a long aluminum slat.

In total i needed ca. 42 meter squared timber.

2x 500 cm longitudinal beams -> 10
5×115 cm cross beams -> 5,75
10x 150 cm frame beams -> 15
1x 300 cm v-shape in front of the jig -> 3
2x 80 cm S frame beams -> 1,6
4x 150 cm bracing beams -> 6

Hull construction is getting closer!
