Ryan -- the F305s seem pretty hard to come by! First, you should probably accept the fact that you will be moving a boat from wherever it is to your location. It's not as hard as it may seem, just takes a little coordination and of course $$. I just bought a F285 and here are some suggestions on good places to find boats:
1) Yachtworld.com (these are all brokerage boats, you can search by nationwide and worldwide). They have two active listings in Canada right now, the links:
http://www.yachtworld.com/boats/category/type/Beneteau/38+Moorings/Canada/Bainsville/3
30'
Beneteau First 305 198741,985 S U S D FG Halifax, NS, Canada
30'
Beneteau First 30e 198340,935 S U S D FG Lake Champlain, QC, Canada
2)
www.sailboatraderonline.com
3) Sailboatowners.com - guessing you've already checked this one since you're posting on here : ) !!
4) Google "craigslist search" -- there are a few ways to do nationwide searches on craigslist. The F305 probably isn't the caliber boat you normally find on craigslist, but it's worth a shot. Boats on craigslist tend to be cheaper than through other venues.
5) Ebay -- check it once a week.
6) You can also google "beneteau first 305 for sale". It's another shot in the dark but every now and then listings show up from oddball places.
Good hunting!! I found my F285 on yachtworld, but for some reason it actually didn't turn up until I got there through a google search.
