I hoped that such a service was available but couldn't find one.
Since I also wanted the RCA's to show on my chartplotter, I played around with the system & was finally successful in getting them accurately positioned. I used the co-ordinates provided on the dfo site to create waypoints on the chartplotter. I then simply linked them together by running a "route" from waypoint to waypoint. I saved them & now store them on my gps with my other routes. You can also change the colors of your boundaries to better highlight them on your gps. I made mine red.
The process takes abit of time but sure has been worth it for me. One tip I would pass along is that you will need to zoom in on the co-ordinates to get them accurate to "one second" of a degree. I actually got quite quick with the process after I did the first one.
Hope this helps.
