I found an interesting site - pdq36.blogspot.com - where someone added hull extensions to a PDQ 36' cat. The idea seemed great from my point of view, in that a cat will probably be in my near future, and I don't want/need anything bigger than 36' for 2 people, but would like to have extra carrying capacity. The idea of hull extensions is very appealing, since the extra weight would be on the stern, with a generator and dinghy plus misc. hanging from the stern. What I don't know is how that would affect the design and performance of a cat. And if it would be so much better, why wouldn't the factory have done this? Is this a viable idea that could be used on any cat?
