    Hi Guys , I have a doubt about the position of the steel ladder to climb to the Tuna Tower on a Fish Boat. Why the location of the ladder is lateral and not central ?
    Could anyone give me pdf about the drawing of Tuna Tower?
    Thank you so much for the support

    Tuna towers are usually aluminum to keep the weight down. Tuna towers are often designed for the particular boat. The trend is to have a unique customized tower.

    Hi Satan,
    there are no rules about the position of the ladder. It will depend on the layout of the deck and the flybridge.

    However, in general a central ladder requires a hole at the center of the flybridge (if it goes through the flybridge), which can be inconvenient and increases a danger of inadvertently putting one's foot in it. This layout also makes getting on and off the ladders from the flybridge more difficult, because there are no handles around to hold on to.

    A lateral ladder allows you to keep your hands on the flybridge guard rail during stepping on/off the ladder. And in general it leaves more free and usable space both on the main deck and on the flybridge (again, depending on the specific layout of your boat).

    My two cents worth.

    Cheers

    Oh, now I realize that you are talking about the tuna tower and not the flybridge.

    Well, the reasons are nearly the same, and plus the lateral ladders can be a structural part of the tuna tower, which saves the weight.

    Cheers

    I'm guessing he wants to know about the motion of being up high on a tuna platform at the stern VS more midships.

    Doubt it, lateral means side, the side of the tower.
