TY for the suggestion it help me to find the problem.

i place in the boat a script name R R,its a script that that make the boat in a motion rock and roll.the boat move up and down and rock.the script go on when you stand up.The root prim become convexhull so impossible to go in the boat and the physical become no use because it become convexhull to.T correct it you have to use a good script remover, because even you take off the script to boat still rock and roll.

That is a little peculiar, but you had at least one link in the linkset that was already convex hull -- the part that you created as mesh and uploaded.  When you sit or stand up, you are changing the linkset.  That action may be enough to trigger the servers to make the rest of the object convex hull too.  In the end, though, it should be an advantage for you because the L.I. of the boat probably decreased, unless you have linked cut prims to it.  Why are you concerned?
