I'm brand-new to Shipbucket, and wasn't sure where to make this comment.
I'm enjoying comparing the hovercraft drawings provided in the main drawings section, but I noticed that the drawing for the SRN4 Princess Anne cross-channel ferry isn't correct.
The drawing is here: http://www.shipbucket.com/drawings/1555
The SRN4 Mark III was 56.38 meters long, but the drawing shows it as under 50 meters long. I didn't check whether other dimensions are correct.
I imagine it is worth fixing the SRN4 drawing primarily for the sake of accuracy, but there would be an amusing side benefit as well. For years, the two SRN4 Mark III ferries which crossed the English Channel were the largest hovercraft in the world. But then the Russians introduced the now well-known Zubr air cushioned landing craft which, curiously, at 57 meters long, were 0.62 meters longer than the SRN4 and captured the title of "world's largest."
When I discovered Shipbucket this week, one of my first thoughts was to compare the SRN4 to the Russian craft, and that's how I noticed the discrepancy. As a newbie, I lack the knowledge for how to fix the problem, but I thought I'd mention it.
Also, while I'm here, I wanted to note that among the other hovercraft drawings on the main site, the Spanish (not British, so this is off-topic I guess) hovercraft designated the VCA-36 was listed as never built.

The VCA-36 was, in fact, built - and this website has lots of information about it from when it was first designed to when it was scrapped:

(Spanish language, but google translate does a great job if you need it.)
Unfortunately, the shipbucket image also includes a depiction of the VCA-4, which was planned but was never built. If the two drawings could be separated, perhaps the VCA-36 drawing could be moved to the "real designs" category.
Thanks for including hovercraft in shipbucket - it has been great looking at the drawings and reading the associated postings.
