Just Re the water in cockpit at 5 knots plus Shea.
All the Marks have different cabin floor levels [in relation to bottom of keel].
I hadn't thought about the cockpit floor before Shaun's remark. Something I will have to investigate.
As to the Mk 1 and 5 knots plus Shea, I always wear sea boots [unless its warm water] to combat the problem.
If Shaun is right there must also have been a small design change in the Mk 2 & 3,
but I suspect it may be because of the weight of our inboards being so far aft.
It may also explain that some re-engines have been moved forward to try and address this problem.
In addition I removed 70kg of lead stored in the bow of Seaka when I brought her, was it an effort to raise the stern?
All food for thought
