Bletchley to Island Line

[Bletchleyite]

With all this talk of the Island Line I'm tempted by a Ryde (!)

Fares from Bletchley with NSE are thus:

I note the Any Permitted ones are routed either Wightlink or Hovertravel, but there's also a Kensington Olympia one which I will probably use and save a few quid.

Which ferry route is that valid on?

NRE showing itinerary via Portsmouth Harbour and Ryde Pier Head, so Wightlink FastCat, but I notice on brfares it shows the Red Funnel in the restriction text (Restriction: UT - same restriction on the AnyPer+Wightlink ?! )
