In the third sailing vessel rescue off the Atlantic coast in a week, three sailors were hoisted this morning from their 30-ft. sailing vessel 25 miles east of Cape Hatteras, N.C., after fighting 15- to 20-ft. breaking seas and 35 knot sustaining winds for about 15 hours. John Springer, 35, of Mt. Pleasant, S.C., Wayne Ryland, 59, and Janine Ryland, 34, both of McHenry, Ill., were on the sailing vessel Bath en route to Charleston, S.C., from Maryland when they encountered rough weather. The sailors contacted the Coast Guard via VHF-FM radio at about 7:30 a.m. today requesting to be evacuated. "This case, coming right in the middle of National Safe Boating Week, illustrates several important points that mariners should keep in mind," said Lt. Cdr.
