Driving home from our boat yesterday we drove through the tiny town of Bayside.* Bayside is the home of the Rozema Boatworks http://www.rozemaboatworks.com
, a company that specializes in aluminum utility boats like crabbers, oil skimmers, etc.* They've also built a few recreational boats based on their commercial boat designs.
These two brand new seine net boats were sitting in their yard.* These are the very powerful boats carried on the sterns of purse seiners that are launched to pull the net around a school of fish.* The net is paid out from the net drum on the seinger and the net boat hauls it around in a big circle back to the seiner.* Needless to say, these ilttle boats are very powerful.* Big automotive gas engines used to be the powerplant of choice* but I believe all the ones built today are diesel powered.* I don't know what's in these two.
The underside of the boat is designed so they can literally run over the net without fouling the net or the prop and rudder.* Some net boats have "normal" rudders.* These are the first ones I've seen that use a Kort nozzle for steering.
Great examples of form following function in the purest sense.
