The hull is covered with small mussels – this is another reason we are going so slow. We cleaned the bottom completely prior to departing from Galapagos, but it seemed the first several days of slow drifting in nutrient rich water got them established on the hull and they have been happily growing and multiplying since then. It's not calm enough seas for Michael to dive over and do some at sea cleaning (though mussels in marinara sauce - yummy)
But we are making progress across the big Pacific. And we haven't killed each other yet!
