Hi Cam,
In addition to the estimates Don gave, here are some additional considerations. If your new boat has the tall rig, (double sets of spreaders), your halyards will need to be longer. I didn't see any mention of the staysail. That will need a halyard and sheets also. I used 1/2" for that. On the yankee sheets, 5/8" is good, but you can go larger, up to 3/4" if desired. Don's figure of 75' is for each yankee sheet, so you will need to procure 150'. Do you want a spare halyard, there should be an extra sheeve for that at the mast head. Will you be flying a spinnaker? Roller-furler control lines, topping lift will be smaller diameter low stretch.
If I were in your situation outfitting a new to me boat in a remote place, I would probably take these calculations and purchase partial spools of 1/2"and 5/8" and not cut any of that line until it is fitted to the rig. This way you can be sure of the measurements and not be caught a wee bit too short. Shipping it from Atlanta or purchasing it in Sint Maartin would depend on cost and availability.
Good luck! Matthew
