Sorry dozing at the computer... correct... seen as I'm up and you are sensible in bed (that's what happens when kids stay up late and the dog still not snuggled down for the night has a barking campaign) I'll post another.

Set in the 1800's/early 1900's set around ships that sailed around the world and brought all sorts of complications for the owner and his family.

The Onedin Line?

That was quick correct.

You posting or me???

2 kids shows:

One the kids wear a belt that is a sort of transporter
The other, the kids crawl through a fence into another dimension

On a roll

Tomorrow's People?

No idea about the second one.

correct, the other was timeslip

Not sure if many will remember this US "short lived" series, but here goes:

A computer generated superhero and his human creator fight crime in their city.

I dunno bout that one but it sounds a bit like the hoff with his sidekick car "Kit"

Would have to agree that would be Knightrider would it?

OK they had a van there was at least 4 of them, a mult-racial team and they got into all sorts of scrapes but always came out the good guys.

No, not Knightrider.

b*gger 2 secs till I think again.

Need another clue for yours... and mine featured gold jewellery heavily.

Guess yours was the A-Team?

Second clue:

This crime fighter duo could only opperate at night due to power consumption.
