    Triton ISA bow stop vs older design

    What is the difference between the newer ISA "inovative slide adjust" bow stop vs. the older style? Does it provide more front to back adjustment. Researching parts diagrams they both loook like they slide on the welded plate to the frame and are held by two adjustment bolts. Is there more height adjustability for the bow roller? Looks like ISA came in 2014.

    Thx
    Mike

    I think what the ISA means is that the movable winch rail slides forward and back and the winch tower can slide along the rail. This allows more total adjustment distance.

    The older Triton winch design the tower was welded to the front end of the movable rail, then the entire assembly could adjust forward and back.

    There may also be more vertical height adjustment range for the bow roller.

    Do you think there is enough bow stop adjustability to accept a 7.5 ft standup on one side of a double trailer? Any easy way to get the bunks vertical?

    I have a Kawasaki SXR-800 which sometimes sits on one side of my Triton double trailer.

    I have modified the trailer with a third set of bunks just for the stand-up, so it usually goes there now.



    There is a third Triton ISA winch tower assembly up front, no issues with adjustability for the stand-up.

    2x4 bunks are too wide for the sculpted Kawasaki hull bottom. The standard bunks can be moved close enough together to sort-of support the hull but the stand-up will end up canted to one side or the other.

    If you want to change the bunks on one side to be a better fit for a narrow width 2-stroke stand-up hull, there is a way to position the bunks closer together than the factory bunk support rails normally allow. Involves aluminum welding, but doable by any competent aluminum fabricator.
    I used 2x3 boards for the stand-up bunks. Double stacked as I wanted the strength/stiffness and I have longer than normal bunk lengths.

    Triton sells additional/replacement bunk hardware and brackets so you can make another full set of bunks with 2x3 boards (or whatever) and swap them onto the trailer when needed. Only four nuts need to be loosened and the brackets (with bunks still attached) can slide right off the slotted base rails.

    Tip: The long horizontal stainless bolts that connect the bunk to the support bracket are an unusual length (just over 5 inches?). Might be easier to buy the bolts from Triton rather than chasing around in local hardware stores.

    Mark the trailer where the brackets need to be bolted down for the standup and you could probably do a full bunk set swap in 30 minutes or less.

    Thanks for the information. I also have an SXR-800. What is your bunk spacing (center to center) for your 2x3 bunks? I am running vertical 2x4s spaced at 12 in. It fits inside the inner chine and partially on the ride plate. It can't slide side to side and is self centering when loading. Instead of cutting and welding the bunk mounting plates on the frame I may use u-bolt vertical bunk brackets and just clamp to the frame.
