I'm on Vancouver Island in British Columbia. I built a version of the Z-Drifter a couple years ago but have found that it isn't seeing a lot of moving water. It has a 1/4" fir shoe covering most of the bottom. It is a great boat on lakes however it does need to be trailered so the cost of ferries and travel, in general, is costly. 

I would like to offer it here for sale, or trade for about $1500us with the trailer. …
