It's only up on the foils at high speed, and it was actually pretty stable by the end of the program when they had gone through a few iterations of foils. It looked like a normal boat when it's just slowly putting around or docked.

Their thinking was that the ship would be able to sprint from point to point while taking sonar readings, to be able to triangulate and hunt down Russian subs, similar to how an asw helicopter works, in fact it was the Sea King asw helo coming into widespread service with the RCN, in conjunction with the addition of aviation facilities to the St. Laurent-Mackenzie-Restigouche-Annapolis family of destroyers that ultimately killed the Bras D'Or program.
Only useful thing I could think of now would be for stuff like missile boats, or maybe integrating foils into a sea drone for going even faster during the terminal strike phase.

The only real benefits over an asw helicopter would be endurance/persistence and magazine depth. But yeah, that's why they never went anywhere with it.
