Without that you can keep ramping the installed power up and up and barely get any improvement in speed. The ship will accelerate faster, but it'll quickly hit a wall (quite possibly at below 20 knots) where its high drag hull simply can't be pushed noticeably faster -- no mater how much more power you throw at it.
You need both better boilers/engines and better hull forms to achieve higher top speeds -- but they're two very different fields of research and expertise and improvements made in in one doesn't ensure you'll have expertise or ability to make improvements in the other.
Although I do not want to take Penny's side, there is a slight counterpoint.
At least if you have the steam turbines, then you will realize the need for better hull design and better propeller design (maybe even trying a toroid design). It is true that there will still be much work to be done, but some technologies do co-evolve. Turbinia did start a revolution in ship design.
