Ok I have to make a confession. .... I didn't know what an RIB was.
Rigid Inflatable Boat. I believe.
I used them in Malaysia and we went 20 miles out. They're really stable as long as you don't get a hole in them. <img src= " height="23" srcset="https://spearfishing.world/forum/images/smilies/emojione/1f606@2x.png 2x">
