    I just bought a 24 Captiva fishing boat. Someone built a foam filled reverse chine on the boat, I think because used for commercial fishing get more weight capacity and stop rolling. Look like huge, I just don't know what is the advantage vs disadvantage keep it on the boat, or just remove it. Thank you for any advice, I don't know anything about chine design, just looks over sized.

    I'd say leave it be, unless it is giving you some kind of grief. But you'd likely need experience in the same hull without the modification, to gauge what difference the alteration is making.

    Only I find one other for sale, over 2000 miles away, little bit difficult to go there for test drive What do you think will be worst or better ride than original hull before modification? Will be go on plane easier, or will be slow the boat down? I'm sure will stop rolling.

    re: Captainboatcollar
    That is interesting! Give me hope, maybe that large chine not bad at all! I think I just try like this. I got the boat with locked up engine, I'm almost ready to put new 185HP International diesel back, so I will find out soon how the boat rides.
    Thank you

    You would expect the ride to firm up, but you may also be able to hold plane at a lower speed. Not easy to predict, some angles to the waves may be better, others worse. Without a head-to-head comparison of the two boats, hard to say. But for sure, it will be a little steadier at rest.

    Tom Lanthrop designs Bluejacket boats. He is a regular here. His boats have extended chines & rise onto the plane without (climbing the hump).

    Here is a link. http://bluejacketboats.com/planing-boat-theory/

    Eric Sponberg very successfully modified a fishing cruiser using foam lifting strakes. Full report below.

    See how your vessel behaves first.

    Addendum. That transom looks like it would have been a great landing spot for the only 557 hp outboard available. http://www.seven-marine.com/

    You always have the option of removing part of the additions, if necessary, it isn't a matter of all or none. But it would want to be a genuine issue to make it worth doing.
