    Hello,

    Theoretically, for the small craft (<16') which one handles the best in rough water (4'+) and most sea worthy -

    planning V hull powerboat
    classic sailing hull
    planning Cat
    planning Trimaran
    jet-boat hull
    mini-speedboat
    Pontoon
    or PWC?

    Thank you.

    cat

    It's one of those 'big' questions, and a full answer should begin with "it depends" and then be long and complicated :) but if I had to shorten it to one word I'd say 'cat'

    Where my money is at.

    I would say a monohull with self righting as a main property. Both in shape and ballast. There is a guy called Sven Yrvind who has done this and sails his "coffin" around every where. My guess is that that is the safest way.

    Since it's light it is on the waves and with a sail it has calmer motion, even though its a bit slow for some ppl. (it can plane though)

    Several people have told me RIB's (rigid inflatable boats) because of their extra buoyancy.

    RIB's is good, anything with a big controllable engine like an outboard really!

    I suppose a RIB would fit under his "planning V hull powerboat" category? Anyhoo, my vote would be RIB or PWC. Expect to get plenty wet, no matter what the choice.

    To start with: There is no small boat under 16' that will be comfortable in four-footers. There are plenty that are safe and controllable at various speeds, but do expect to get tossed around. My vote goes to a deep-V RIB for planing hulls, and something round-bilged with a full deck and self-righting ability for displacement hulls.

    I add to this opinion.

    In the fall at lake erie ,sailboaters go playing in rough weather to get the last hurra in . seems to me mono hull sailboats ride the best!

    Lake Erie is typically short choppy waves - noticably more when the wind is up. Is this the same fall weather you are describing?

    If so, then a more inclusive large "dunking wave" found in Lake Michigan or lake Huron (deeper lakes by comparison) should also be considered.

    That short choppy stuff is just plain annoying.;)

    that short choppy stuff sinks supertankers....also your downeaster are real close to the sailboat hull design ;boats with some draft are better riding than tri hulls or cats in real serious seas .lake erie has shallow water and cold dense air in the fall , this makes for some larger waves!

    This has tested to work well up to 1.2 m high waves. LH 4.7 m, BH 2.5 m
