What Is Mile Building and Why It Matters
Mile building bridges the gap between RYA training and true offshore competence. It’s where you take what you learned in a Day Skipper or Coastal Skipper course and put it into practice on extended passages — often in unfamiliar waters and real-world conditions.
Time at sea is the greatest teacher. The more miles you sail, the more you experience: different weather systems, changing sea states, unexpected challenges, and the occasional thing going wrong — and crucially, how to deal with it. From minor gear issues to fog, squalls, or night navigation surprises, every scenario you handle builds judgment and seamanship.
That experience is valuable at any level — whether you’ve just earned your first RYA qualification or you’re working toward Yachtmaster Offshore.
Mile building isn’t just about collecting miles; it’s about becoming a sailor who’s calm, capable, and adaptable in all conditions.
