Kriging Barrier Polyline

Dear all,

I am trying to create a raster dataset from a vast number of bathymetric data points. I want to use the kriging method with a cell size of ~20m but when I create the raster surface it is interpolated beyond/outside the zone where the points are located resulting in a surface that is fine within the point area but is incorrect outside. I know that a barrier polyline can be used for the IDW interpolation method to prevent this from happening but does anyone know a way of doing this in the kriging method as the barrier polyline option is not available?
