Deck supporting Role !

The instructions quote dimensions of where to place the deck supports as well as the dims for the shroud drilling points. ( yes , I am jumping a little ahead of the instructions) will explain later !

But...... given the hull has a good curvy shape, the initial 30mm dim from edge of the hull is not easy to mark or measure from with a straight ruler !

To get a work around for this,

I used some waste material to make myself a spacer marker, the upper part is 30 mm width and it is is glued to the side piece that butts up to the edge of the hull. simply move the piece along the bulwark ridge while marking the deck as required.

Then you will have consistent, parallel 30 mm marking on which to base the next important dimensions on !
