    Some guys like small trawlers, 25-40 feet or so. While researching them I recently found out a lot of them are made by those clever Norwegians. They're usually aluminum, and apparently very well designed, real tough to ply artic waters around Norway and Iceland. Of course proper heating, including heated windows, and some even the main deck. Supposedly comfy, well appointed interiors, etc. One guy said that some people when converting to liveaboards, insyall watertight hatches on the stern, just above waterline, for easy access to swim, dinghy, etc. A lot to like about these Scandinavian beauties.

    Beauty is in the eye of the beholder.
    I suspect those are designed to get the maximum capacity within a regulated maximum overall length.

    Yes, and some Alaska boats are short and beamy because of gov regs too, like the Fred Wahl 'famous 58s', which are bigger, like 58X28, and of steel, so much heavier. Since these are shorter, theyre better for marinas that charge by length.

    I can understand admiring their efficiency at exploiting the regulations but aesthetically they are a bit indigestible.I don't suppose any of them were designed to move easily through the water with equal efficiency.They are strictly tools for the job.

    Sure, some hulls are more efficient than others, and those guys that have less efficient ones dont mind. Usually we weigh in all factors, all the many tradeoffs.

    Those things are the result of some arbitrary rules, i'm more impressed by:

    "The 99‘ x 28‘ (30.2m x 8.6m) Immanuel is the result of a government/business collaboration, namely The Netherlands’ Masterplan Sustainable Fishing Foundation.

    It was designed by Kramer Marine Engineering (Zwijndrecht), utilizing CFD software from D3 Applied Technologies (A Coruña, Spain), and working from initial input from MARIN (Wageningen). In plan form it is wedge-shaped, with a near vertical bow. According to one description, it has “a full body amidships and a wide and relatively flat aft ship, with little transom immersion.” Wider sections above the bow waterline are intended to create reserve buoyancy and reduce spray on deck. Engine cooling water enters one side of the short and wide bilge keels and exits the other, eliminating external pipework that causes drag.

    Immanuel is a diesel-electric hybrid. Hydraulic systems that include pumps, as well as the windlasses, cooling system, and transformer, are powered by permanent-magnet motors governed by Unidrive M variable-speed drives from Control Techniques."

    Im sure thats a wonderful boat, especially that its already hybrid. But waaaay bigger, and will be way mor expensive too. Guess its aluminum too, will check it out, thanks for submitting it.
