The company, Aldura, that used to make these is long gone, and there aren't many out there.

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

► While the Miami International Boat Show is renowned for its extravagance of all genres, and the debauchery of power displayed by many of the boats on show, the reality of the overall American boating market is far less spectacular: hulls under 26 feet are flooding a market more oriented towards inland waterways and protected bays than the open sea. In this context, the all-new WorldCat 235TE, developed from the 235CC Center Console, offers serious advantages in a compact hull - especially when compared to a monohull fishing boat of the same size. The 235TE boasts 35% more deck area, gets up on the plane three times faster for the same power and, above all, delivers fuel economy of around 40%. Range promises to be remarkable for this size of powercat, thanks to twin fuel tanks totaling 120 gallons (454 liters). During our visit to Miami, we were able to appreciate the practicality of all the fishing gear, as well as the remarkable quality of construction and finish. ► TECHNICAL SPECIFICATIONS Builder: WorldCat Length: 22’7” (6.88 m) Beam: 8’6” (2.59 m) Draft: 9” (23 cm) Transom height: 25” (65 cm) Light displacement: 5,275 lbs (2,393 kg) Max. engine power: 2 x 300 HP outboards Fuel capacity: 2 x 60 US gal (2 x 227 l) Livewell capacity: 30 US gal (114 l) ► Become a FREE SUBSCRIBER to Multihulls World's YouTube page now - https://www.youtube.com/c/MultihullsWorld ► Log on to our website to discover over 500 multihulls tests!
