steps are more for speed, thay pull air in, and or brake the clinging of the water on the surface of the hull, rule number one on go fast on the water is
" you must get your hull out of the water" steps help
trim tabs, ya you really don't need them under 7m, thay make auto ones kinda nice for smaller hulls with heaver outboards, keeps the nose down.
used to level off big hulls, a lot depends on the hull,
this hull is 7.1m she got 235hp on it when you lite it hole shot she comes up and she will start to lean left cuz of torque, would be nice to have tabs to to balance her out,
