The usual ferry route is London Liverpool Street to Harwich then a boat packed with White Trash smoking in every coner of the ship and no outside decks to go out to for fresh air. Then it's a wait aroung in Rotterdam for your train to Amsterdam. Times are roughly London-Harwich 1hr30min, boat 4hr, Rotterdam-Amsterdam 1hr. Including waiting you are looking at pretty much the entire day. It would cost about 70 or 80 USD.

I'd tend to agree with Dambus. The eurostar would be a much more pleasant experience and would allow a few hours to explore Brussels and/or Antwerp.

You may have to buy your Brussells to Amsterdam ticket separately so you'd need to visit www.thalys.com in that case.

Both of these options seem great when planning them, but I've done both and they suck after the first hour or two. I'd just get a cheap one way with easyjet and cut out the hassles. Or even better get a cheap one way on BMI, KLM or BA and get some status miles for which ever program you are in.
