For the rivers other than the Columbia you can get the "Anchor-Eze" setup for the bow of your boat, they will run around $175 and a can type anchor will run you around $75 - $90 depending on how heavy a one you get. I have a 65 lb for my sled. 100ft of 3/8 no stretch should be good for this set up. I picked up the puller at Woolridge in Seattle. If you want it welded on they will do it for an extra $25.
Good luck and tight lines, Jeff
Isn't that why they call it a hole in the water you through money into?!?!?!?!
