1) Understanding your energy needs is essential to determine how much solar you need. Start by making an "energy budget". List all your consumers and their daily usage. For example, if your LED lights use 1W per bulb and you have eight bulbs on for 5 hours a day, that would be 8 Watts for 5 hours or (8x5) 40 Wh (Watt hours). I like to use kWh to keep things consistent. 40 Wh = 0.040 kWh. It's a good idea to list what you're using while at anchor and another list of what you're using while underway (for instance, you don't use your autopilot at anchor). Remember to list everything: fridge, freezer, watermaker, autopilot, nav lights, chart plotters, etc. For example, here aboard Athena, with an electric galley, fridge, freezer, watermaker, two computers, etc, we use an average of 5.5 kWh per day. 2) To give you a quick estimate, use https://globalsolaratlas.info/ to find "Global horizontal irradiation" per day for your location. Take your daily energy consumption from step 1 and divide that by the number of solar hours. In the case of Athena, located in the Caribbean, that would be 5.5kWh per day / 5 sun hours = 1.1 kW solar array. Keep in mind that this is a theoretical number that does not take into account the shading or degradation of the panels over time. Let's add 30%. 1.1 x 1.3 = 1.43 kW. You can now divide that number by the panel's Nominal Power output. In the case of Athena, our panels are 400W SunPower panels. 1430W / 400W = 3.6 panels needed to cover our 5.5 kWh per day consumption. 3) Understand that the amount of solar you can install on a small sailboat is limited by the size of the boat and heavily influenced by shading and, of course, the boat's location. The size of the panels might also be defined by the height of your stanchions or the size of an existing solar arch. Figure out where you're able and willing to install panels. That will dictate the size and number of panels. 4) Use Victron Energy's MPPT Calculator to calculate what MPPT is ideally sized for your solar panels and expected output based on location. Based on our experience in the Caribbean, the estimate provided by the guide is reasonable. https://www.victronenergy.com/mppt-calculator. Remember that it's best practice to avoid combining panels with different specs on the same MPPT. #sailboat #sailboatproject #boatwork #saillife #liveaboard #liveaboardlife #saltlife #sailing #sailingadventure #travel ingcouple #livingonaboat #solar #sailboatsolar

As the 48th Rolex Fastnet Race moves through its fourth day, the flood of arrivals continues. The window of opportunity for those pursuing overall victory is narrowing and, after four days, crews still at sea are beginning to tire. Finishing well is dependent upon full commitment to performing at the best of one's ability and remaining resolute until the finish. The American yacht Wizard is currently in top spot, but the prevailing characteristic of Rolex Fastnet Race crews is to persevere to the very end, meaning the result remains in the balance. Nearly a century old, the Rolex Fastnet Race remains one the most inspiring and recognizable offshore racecourses in the world. Supported by Rolex since 2001, the race is organized by the Royal Ocean Racing Club, and the 2019 race has attracted a record fleet of 388 yachts ready and willing to test themselves against one of the toughest of offshore races. Discover more https://on.rolex.com/2YI5bKv Rolex has always associated with activities driven by passion, excellence, precision and team spirit. It naturally gravitated towards the elite world of yachting six decades ago and today supports the most prestigious clubs, races and regattas. The brand is Title Sponsor of 15 major international events – from leading offshore races, such as the annual Rolex Sydney Hobart Yacht Race and the biennial Rolex Fastnet Race, to grand prix competition at the Rolex TP52 World Championship and spectacular gatherings at the Maxi Yacht Rolex Cup and the Rolex Swan Cup. It also supports the exciting new SailGP series, where national teams race in supercharged F50 catamarans on some of the world’s most famous harbours. Rolex’s partnerships with the likes of the Cruising Yacht Club of Australia, Yacht Club Costa Smeralda, Royal Ocean Racing Club, New York Yacht Club and Royal Yacht Squadron are the foundation of its enduring relationship with this dynamic sport. #Rolex #Perpetual #RolexFastnetrace

This has to be one of the coolest boats I've ever seen! If I had lakes around my area I would definitely buy one of these things! I might still buy it! Let me know in the comments if you would be interested in buying one of these!
