Ah nostalgia, not what it once was
I too used the various hovercraft services to the IoW in the 60s and 70s, and even as recently as last year on the current Southsea-Ryde service.
Somewhere I have a photo of my wife doing a filmstar descent from the SRN2 (I think) that was used on trials on the route for a short while. I recall it being HUGE compared to the SRN6s which we were more used to.
In an associated note, I worked for BR in the 70s and spent some painfull hours hovering back and forth across the channel in the APU bay of various SRN4s taking oil samples from the hydraulic system. There were no doors or windows and a screaming Rover APU turbine about a foot from my head the whole time. I've had more comfortable journeys......
On the subject of FS04 hovercraft, I've played around with Hama's earlier one to try and get it to 'skid turn' like real ones do with some success. As I recall it's a matter of raising the roll stiffness to a high level to stop it banking on turns. I note his SRN6 doesn't bank at all, thank goodness, but it doesn't skid much either, and at high speed (50 kts) it's the devil to turn anyway.
I forsee some .cfg file editing coming on
In passing, I tweaked his Boeing Jetfoil in the opposite direction at the same time so that it leant MORE in the turns, and that worked a treat.
Now there's a thought for a Brit Classic connection. There was a P&O service using Jetfoils that ran from Tower Pier to Ostend in the 80s, I travelled on it once (at my employers expense

) and I'd assumed we'd go down the Thames hullborne, but not so. The Captain had her up on the foils just east of Tower Bridge and we zapped past Greenwich at about 35 kts and 20 ft off the water, leaning into the turn where The Dome is now in magnificent fashion! Pity they stopped that service.
Somewhere I have some photos of that 'aircraft', maybe a repaint in the P&O scheme may be in order.
