    Steel Shot Bags - Stress on Hull?

    Doubt there has been any studies on this, but I was just wondering if anyone had experienced any hull damaged due to the use of 50 lb steel shot bags. Currenly I have 50 lbs on port bow,50 lbs starboard bow, 350 lbs mid port (offset prop rotation) and 100 lbs mid starboard for a total of 550 lbs. Since these bags remain pushed up again my hull at all times, I was just wondering if anyone had experienced or even thought as to whether they may cause hull damaged in the future.

    I will try to answer with simple logic
    Knowing that you have ballast as standard or as an option in your boat and that the boat can carry x people, the added weight should not be an issue. The other part of the equation is: are here any stress points created due to the location of your bags compare to the location of the default ballast/people. I might say, the manual does not say that there are locations in your boat where you should not walk or stay on. Assuming 150 lbs an average Joe standing on 2 foot, that is 75 lbs per legs. I guess you should be good to go to put your bags wherever you see some seadeck.

      These hulls support a tremendous amount of weight in motor, fuel, gear and passenger. Plus take incredible pounding from waves/wakes. I can’t fathom how 100lbs here and there even on a long term basis could cause an issue.

        Well I guess I'm good to go because all my bags are on the Seadeck underneath the seats

          Are you going to tow your boat or keep it in the water? Trailering puts far more stresses on a hull than sitting or being used in the water. Every bump in the road is a concentrated stress on the hull. A hull full of lead or steal takes a even greater beating on the road. It's also critical that a boat be bunked all the way to the transom on a trailer. Do not have the boats transom aft of the bunks.

            No my boat stays on my lift or in the water. I dont even have a trailer. I can see how these bags would put more stress on the hull while trailering

              The biggest thing to worry about there is overloading the trailer or your tow vehicle. You aren't going to crack the hull on one of these boats with shot bags. They're built like tanks.

                Understand completely. Just having 350 lbs in a small concentraded area under the port observer seat for a very extended time was the reason I posted this thread. Based on the replies from everyone I feel ok

                  I know guys running 1000lbs of lead on top of 6k lbs of water ballast. You will be good. I keep 400-450lbs of lead in my boat at all times too
