Can a sharpie-inspired trawler's lively movement be tamed?

    the boat picture has almost a flat bottom at the stern

    is probably relatively narrow for her length

    has a bit of cabin above

    the OP would be wise to ask what to look for in a new boat

    BlueBell "Whatever..."

    A test drive.

    Dare I suggest something very much in 'left field' - a power cat?

    For longer distances, much better. Poking around at 7 or 8 knots, no wonder the OP went wide looking for the current, on his long-haul trip, and of course when the current has an opposing or near-opposing wind, you get nasty wave patterns.

    Bigger, heavier, rounder bilges. Yes to all three.

    Re. Power cat: I have been looking there, too. Are there any makers whose hulls you regard as being suitable for longer blue-water passages?

    Re. test drives: I wanted to do just that with a 54' solid fibreglass boat I looked at (with paravanes, over twice the displacement, and round bilges), but the owner wanted me to make an offer acceptable to him before doing a sea trial. I understand this and it is becoming more common. His point was that the sea was ~two hours away from where the boat was docked.

    My boat is relatively beamy at 4.03m, but with flat aft sections, as you noted. The next boat will be longer, similar beam, rounder bilges, greater displacement, perhaps with ballast, and some kind of stabilisation. All other suggestions gratefully received!

    You mean pay for taking the boat out for a trial, not make an offer to buy it ? I think it is reasonable to pay for a test run, with perhaps an arrangement for a cash adjustment if it results in a sale.

    No, the owner wanted me to make an acceptable offer before he'd take us out, to feel the vessel's motion. I said I could not make an offer before experiencing her movement, and he said no, make the offer and if accepted, that the offer would be dependent on both survey and sea trial.

    I see, I think a cash payment for a trial, would be reasonable, though.

    I did not think of that. I'll put that one in the data bank for next time! Good idea.

    I don't know how many "tyre-kickers" there are around with boats that size, but with trailer boats, they are in plague proportions, you can't expect people to waste time and fuel on the off chance of a sale.

    Ah yes: "tyre kickers and dreamers"; I have met a number of these in past boat dealings. I know that my next question is a bit like "how long is a piece of string", but if a run took a morning, what would you think would be a reasonable recompense for a few hours?

    what is it worth to find out the boat sucks? I say $100/hr, but start at $50
