ROW = Rise Off Water
By 'tunnel hull' I assume you mean planes with twin floats? Although the names are sometimes used interchangeably, 'Float Planes' are regular planes fitted with external floats, and Seaplanes are thought of as the floating hull type. As far as difficulty, landings and takeoffs are similar in technique to that of taildraggers on land. Not hard, just a little different.
