Hull Measurements to aim for

Hull Measurements to aim for

Below is a table which shows the original measurements and the new measurements I am aiming for. The new measurements were taken from a Windrush Yachts made Tornado hull which is close to the Marstrom hull in the bow shape.

P1010124 original_deck_overlayedNote! The measurements 100mm below deck are slightly larger without a deck on as the deck will be pulled in slightly. The image left shows how much the deck has sprayed without any bracing. You will notice that the front 200mm has been cut to allow the front piece of the deck to open up as well.  So after pulling the deck in I should have similar measurements 100mm down as the Windrush hull. I believe the Marstrom is only slight bigger in a few spots than the Windrush hull.

Note!  These modifications do not change the boat's specifications for meeting class measurement requirements as the first template is measured at or near the first bulkhead which is directly in line with the front jib hound fitting.  There is no template that measures forward of this fitting.  The modified hull will be tested against this template to confirm this.
