Spam-ish perhaps, but none the less to an extent true. Panga type boats.... yamaha longboats or whatever you want to call them, are the number one boat in the islands for sure. They look odd to our eyes as they are so long and skinny, but that waterline length makes them incredibly stable, and very fuel efficient... or at least, they need smaller horsepower to push them along than a similarly sized "normal" boat would need.
Their load carrying capacity is amazing as well....
.... you see boats loaded like this all the time in the islands.
They certainly are comfortable thru a reasonable chop, as their length "connects the dots" of all the chopped wave-tops. However, they don't have a lot of gunnel height, so they do tend to be somewhat wet, which here in NZ with our cold weather and water is a definite drawback.
Personally for here in NZ, I would not want one. At least, not for use in open waters too much. If I were to be operating in more enclosed areas, like the hauraki gulf/waitemata harbour etc, where you are closer to home and can usually find your way in sheltered waters....well, yes, that'd be OK I guess.
Oh, and a boat that size above, a 22ftr, they are usually powered by a tiller steer 40hp. If you were looking for a boat to fish harbours etc with a limited horsepower budget...well, you'd be pushed to find a more capable boat.
