This comes under the heading of stuff done way wrong. A fellow sent me these pictures and noted that the underside gets pounded in any waves. He wondered if I could help. When I saw the pictures, I remarked that it looked like something that John Shaw would do. He asked that I don’t hold it against him. 100,000 lbs. displacement. 71′ length, but looks like around 65′ of real boat. Draft 5 feet. Thinking some kind of wave splitter is the only possible solution. If I could have only done an intervention before it came to this.
Looks like a river boat (or Intercostal). No good options for pounding but increase speed, plain with trim tabs, increase front buyoncy. The fuel consumption is going to increase a lot and also the attention required for driving. Decreasing safety which already looks borderline… You can add splash guards. Mission Impossible!
Easy fix. Just leave those little undersized hulls in place and use them as struts to build a completely new SWATH underbody and raise the boat up about 6′. LOL
