Passing fishermen rescued four boaters who were tossed into the Bay late Monday morning when their motorboat capsized.
The Coast Guard praised the work of the three fishermen, which officials described as good Samaritans.
The fisherman, aboard a 25-foot boat called "Relentless," radioed the Coast Guard when they saw the 12- to 14-foot pleasure-craft flip over, and they hauled the two men and two life vest-clad children aboard, according to Petty Officer Amanda Knutsen.
An 8-year old boy and his 11-year old brother were shivering when Knutsen and her colleagues collected them from the fishing boat but the group, which included the childrens' father and their father's friend, denied medical aid, she said.
The boys were wrapped in woolen blankets for the journey in a 41-foot Coast Guard vessel from a location near South Hampton Shoal to Berkeley Marina, where their vehicle was parked. The children quickly recovered as they warmed up and they became chatty, according to Knutsen.
The accident occurred on a sunny day with light breezes that seemed ripe for an on-water jaunt, but the 62-degree water could have sent the unwitting swimmers into hypothermia within an hour if they hadn't been rescued, according to a Coast Guard statement.
The boat capsized in slight swells, according to Coast Guard spokesman Erik Swanson. "They said the hit a swell the wrong way," he said.
