  • Thoughts on 3rd toon log

    Definitely need to up the buoyancy of my pontoon boat since I renovated the whole thing.



    Current specs:

    Deck is 20'x8'

    Pontoon logs are 19“ diameter, 22.5' long.

    100hp 1980 Johnson outboard.



    Problem:

    currently in the water with eight people on board the rear of the logs are almost completely submerged and the front tips are only 6” from being submerged.



    My solution and question:

    if I took a 24ft long pontoon log, with a diameter great then my current logs, and had the rear of the log rebuilt into a transom, should this in theory increase my buoyancy? Or is the additional weight of the log going to offset the added floatation? Not looking to use the center log for storage.

    Yes, it would increase your buoyancy.

        Would a center log being 25" in diameter compared to my outside logs being 19" in diameter be a stability issue?

        Also do you lose any buoyancy with those center ski lockers?
