Hi, im a bit confused about why you both need this info? I owned a bav 30 for 3years and now wish I kept her. Slab reefing mail sail, std genoa she would go 7.5knts through the water best speed, 6knts everywhere. Always do 5knts just with a puff of wind. Just make sure you reef early, nothing gained by being over canvassed! Apart from the fun of rounding up when you don't expect it.
