A sailing mile builder is a type of sailing trip or course specifically designed to help sailors accumulate nautical miles and gain practical experience at sea. These trips are commonly used by individuals working toward sailing qualifications or certifications, such as those offered by the Royal Yachting Association (RYA), where a minimum number of logged miles is often required. Mile builders typically involve longer passages, offshore sailing, and a variety of conditions, offering crew members the opportunity to enhance their navigation, watch-keeping, and seamanship skills.

Why do a Mile Builder with Infinity Yachting?
Based at Portland Marina near Weymouth, Infinity Yachting is ideally located to access some of the best training waters on the South Coast. Our small crew numbers, experienced instructors and practical hands-on approach help you build confidence quickly, whether you are completely new to sailing or working towards skippering your own yacht.
Our well Vessel Rocket Dog II is the ideal boat for mile builders thanks to her combination of performance, reliability, and onboard comfort. She is well suited to covering longer distances efficiently, allowing you to maximise logged miles while experiencing a variety of real-world sailing conditions. Her stable and predictable handling inspires confidence on longer passages, whether you’re standing watch, navigating, or taking the helm overnight. Down below, she offers a practical and comfortable living space, essential for multi-day trips where rest and routine are key. Fully equipped to meet Royal Yachting Association standards, Rocket Dog II provides the perfect balance between hands-on learning and enjoyable cruising, making every mile both productive and rewarding.
We take a flexible and considered approach to every passage, with safety always at the forefront of our decision making. Weather plays a key role in any mile builder, and rather than rigidly sticking to a fixed plan, we adapt our routes to make the most of the conditions while ensuring a safe and productive experience. This not only maximises your time at sea but also gives you valuable exposure to real-world passage planning and decision making. Throughout the trip, our skippers operate to the high standards set by the Royal Yachting Association, ensuring that all voyages are conducted with professionalism, good seamanship, and a clear focus on the safety and wellbeing of everyone on board.
