MacInnes, known as Puck, is a grinder â sailingâs equivalent of a football lineman. With their brawn, he and other grinders operate hand-powered winches that raise and trim the sails, move the boom and do other tasks that require brute strength.

A study of a cross section of puppies showed that at 6 weeks, only 25 percent of puppies vaccinated were effectively immunized. At 9 weeks, that increased to 40 percent. At 16 weeks, 60 percent responded to the vaccination, and at 18 weeks, that number increased to 95 percent.
Puppy Vaccinations. To help ensure a healthy puppy, vaccinations are a must. When puppies are first born, they are protected from diseases from their motherâs milk. It is not known exactly when their motherâs immunity wears off, so puppies are given a series of shots in order to be protected during this âunknownâ lapse in immunity.
