Not long come off a cruise this week and found a strange channel called BBC Maritime HD.

It used presentation of the old UK BBC HD channel, with promos stating "On Board, On TV, On BBC HD".

It even looks to have its own website here: www.bbchdmaritime.com 

There were no commercials and was showing even the latest episodes of EastEnders from the current week.

Seems strange to continue with the HD moniker, especially given that the TV's in the cabins on the ship I travelled on were old 720p TV's at best.

Which idents did it use?

Slightly off-tangent: I was watching my Blu-ray of Psychoville Series 1 (great series btw) and noticed the 2006 BBC HD 'sting' was used as the BBC ident on that disc. Interesting (but welcome!) choice.

Yes, I know at least one of the Torchwood Blu-rays does this. I think it's because, at that time, DVD releases were still using the 'ribbons' ident on the disc. Obviously this was made in SD, so probably wasn't seen as suitable for use on Blu-ray. The BBC HD sting was quite likely all they had! Eventually (circa late 2009, IIRC) BBC Worldwide (as it was then) had a visual refresh and we started getting the 'purple box' ident.
