I had an engineless Falmouth Cutter for 16 years with some very long ranging voyages.
At first I had an ABI windlass w/200' of 5/16 BBB and a 25' CQR. This ALWAYS kept me put in one place. But the boat sailed like crap to weather. Way to much weight right up in the bow.
I changed over to 100' of 1/4 HT and 200' of 1/2" multi plait. Also got rid of the windlass. still had the 25' CQR. Sailed with this setup for about 8 years. It ALWAYS kept me put in one place also. The BIG difference was performance to weather...she would just take off and effortlessly sail to weather over the seas. Never had a problem hauling this all up by hand.
Of course you will need a second anchor for those really nasty nights. I had a stern anchor that I could easily run up to the bow for this purpose.
Good luck, you'll have a ball. The Falmouth are GREAT boats!
