In looking at small cat designs for a possible build, I've looked mainly at Richard Woods designs, and at Bernd Kohler's designs. I love the simplicity of Kohler's flat bottom trapezoidal hulls, but in almost every other respect, Richard Woods boats are a better fit for me, though their hull
designs are considerably more complex, and time consuming to construct, and have more draft
per inch of displacement
/ less payload.
Maximizing performance is not as important to me as maximizing payload. I have no interest in setting speed records, or racing
, so I consider the differences in wetted area trivial, in fact they become a non-issue as the weight increases in my opinion. Over loading even if one is very careful, is likely on a long voyage.
We all have our priorities, and mine are no doubt different from yours.....
One glaring difference between the two hull
designs is the knuckle which is a distinct feature of all of Richard Wood's designs. The knuckle is above the WL, and presumably serves two purposes. One being to deflect spray to a more horizontal trajectory, and the other is to transition the hull shape, widening it rapidly at the sole. Presumably the area below the knuckle is bilge
, the area above it is cabin
In real life, how much value does the knuckle have in terms of spray....... I'm not fond of a wet ride, but in reality, the cockpit
is well aft. In the center, the bridge deck
is going to block a lot of the spray, and the tramp, depending on it's construction, may break it up a lot. Spray outboard
may be wind
driven into the cockpit
. Without sailing both boat
designs in similar conditions, it's difficult to say weather
this difference is significant.........
Any real world experience based wisdom on this??
