curious which model are you using for this? the built-in 'ford'?
why not navigation tech? if only to align the naming...
can we coordinate efforts on these two components? MB+ has a movement-focused NW at steam power (maritime academy); if you moved navigation school to navigation, we'd at least not have 2 NWs doubled up on the same tech; i'm less concerned about them being close in the tech tree than i am with both on same tech. In return i'll add support for your shoal to MW+ so the storm can traverse it -- as-is i think storm will treat shoal as ineligible for storm (if anyone is playing with both this mod and mw+ and can comment, pls reply)
