What a longer N3 needs to reach 27 knots

Adding G3-like length would improve fineness and machinery space, but the N3 would still need a stronger power plant to approach 27 knots.

Question

Would giving the N3 the G3's extra length and an F3 turret layout raise it to 28 knots?

Short answer

Not by length alone; with more machinery it could probably reach about 27 knots and perhaps approach 28 after further work.

Notes

Extra hull length improves the length-to-beam ratio and creates room for machinery. The N3's four-shaft arrangement could transmit additional power if larger turbines were installed. Length alone does not produce a 28-knot battleship, because the power plant still has to exploit the new space. About 27 knots is plausible after both hull and machinery changes, with 28 requiring more work.
