Check out an old post dated back to 2-27-01 titled "driftboat question". I have replied to the same post before. Use the search function at the top of the page by date. I think you may find out the answer to your exact question. If you still want to know more email me.

In the legend of King Arthur, the Fisher King was a renowned angler whose errant ways caused him to be struck dumb in the presence of the sacred chalice. I am no great fisherman, and a steelhead is not the covenant of Christ, but with each of these fish I am rendered speechless.
