The ratio of bridge deck width to height is what matters, not the absolute figure.

Please note: Bridge-deck/Hull length ratio plays a large part in the effective clearance. I therefore respectfully suggest you should consider this.
And I think the width, more than the length of the deck.

Rather like ground clearance on an SUV, it is the break-over angles, not the clearance.

Also, the location of the minimum matters. A loaded Gemini practically scrapes the water, but the location of the minimum is such that is it not so bad. Worse than others perhaps, but not nearly so bad as the numbers would indicate.

My guess is that these numbers will mean very little.
