    Even fisherman A isn't getting anything for his money. Outside of the speed and load state a bulb is designed for, it's just drag. And a fishing boat will never have A speed and load state. Unless it never works, and never carries fish.

    A few picked up some benefit. But they were length limited vessels and the entire bow was cut and a new molded bulb that was actually significant in a tonnage sense. Not sure if it helped the speed or ride beyond the addition of raw tonnage. But tonnage is tonnage.

    The under 58 cod and pollock boats run at very consistent speed and load, so some benefit may exist. Granted it's a very narrow application of the idea, and it may be an argument lost in the significant figures.


    I got sick of trying to explain that tiny glass bulbs on shallow glass boats did little good and could potentially cause drag. So made a mold and instead sold several, doing my best to make the "least worst" appendage. It's been weird to see various ideas be adopted with very little evidence.

    Admirable. Save them from their own foolishness, and make a few dollars as a hands-on consultant.

    I remember when these four cats were new!
    I had a tour of MV HIGGIT.
    They were conceived as mobile offices for the west coast.

    Those were some small diameter jets for what look like relatively heavy cats.

    Blocked off ports, I thought massive outdrives. You reckon jets?

    Oops. Thought about it. No jet intakes.

    Obviously these boats weren't practical.

    Probably surface drives if no ports. That Probably fits the timing of what was in vogue to spend tax payer money on about the time those were built.

    Our local trooper patrol boat was built with a very expensive transducer for what I assumed were vague search and rescue excuses. They located it below the installed pot launcher they used for enforcement. First pot cracked said Uber spendy transducer so badly it was immediately dead. It was powered with 7 liter mains (private sector sister ships have 18 liter mains) to maintain operational speed they have to run them hard.... and those engines are not long for this world.

    Poorly designed public vessels.... we all have them and feel your pain...

    Yes, this is a lot of boat for little boat.
