I think Aerohead nailed it.
Perhaps the reason we have not seen these strake/fences on catamarans, trimarans and tunnel hull hydroplanes (
be they sail or powered) is the speed they are intended to operate at and also the pressurization and compression of air under the craft squeezes the air to the surfaces (
I'm making this last part up but will attempt to support later).
I have seen a side to side negative camber between the floats/sponsons/pontoons before where the bottom of the bridging element arcs up to prevent being splashed by larger waves presumably. See Concave Tie-Up below in diagram.

The above diagram is to illustrate a side to side concaveness, and recall the original craft (
Advanced Aerodynamic Vessels, SAS) has a longitudinal concaveness.
