How far up the Humber can you go . . .

Keadby bridge on the Trent.

The air draft there's something like 26 feet...

I don't know how far you can get up the Ouse.

Is that at HAT, though? Cos my mast is about 26 feet long. Obviously you have to add the freeboard of the boat (another three feet or so) plus a safety margin, but if it's 26 feet at high tide then I ought to get under it at low. If I wanted to, of course, and if the boat wasn't at the other end of the country :)

The only crossing of the Humber is the Humber bridge. A suspension bridge with 30m clearance above HW so you can go all the way up the Humber

Above the Humber you have two choices. The River Trent or the River Ouse.

Photodog says you can go up the Trent to Keadby bridge.

AFAICS you can go up the Ouse to York Marina, a few miles south of York
