![]() Gel is the cheapest, and the most reliable, simple solution for a house bank. And taking into account the “life expectancy” of batteries in general, including lithium-ion, good old gel batteries will probably be the best option in all cases. ![]() So what? A power boat is not a sailboat drawing power for the autopilot and radar under sail while depleting the batteries… When a power yachts is underway, it charges its batteries at the same time with the alternator! In other words, there is always plenty of current to charge the house bank and at anchor the genset takes over, not to mention the fact that underloading a generator can damage it…Īfter all, it makes little sense to design the specifications of a power yacht as if it was a light catamaran or racing sailboat. But does it make sense on a passage maker crossing oceans under power or with a high power draw requiring almost constant operation of a genset? Many comments and posts on the forums will explain that one can deplete lithium-ion batteries completely without killing them, whereas one may not go below 50% with gel batteries. ![]() But unless the boat is a sailboat or a catamaran chasing undesired weight, what’s the point of saving space and weight on a 20 or 70-ton yacht? And what’s the point of charging faster when in most cases, the generator will be running all night long for zero-speed fins or gyro stabilizer, air conditioning or heating at anchor, or any other electricity-dependent commodity? Reducing the charging time while at anchor or underway on a sailboat, which has no other power source than its main engine makes sense. LFP batteries, if we keep aside the, not so important, fact they are more expensive, also happen to be smaller and lighter than any other batteries, and can be charged faster than gel or AGM batteries. Without going as far as doing the maths with amps, watts and charging parameters, what is, in the owner’s point of view, important to take into account when selecting a house bank for a new boat? Let’s try to remain simple and practical. The li-Ion chemistry is called lithium ferrous phosphate, LiFePO4 or LFP for short, but it’s a long story when it comes to installing them on yachts… And it’s not a mere box-dropping exercise. Not to mention that lithium-ion batteries are becoming trendy in the boating industry. Just like the debate over twin or single engines on a passage-maker, or the raging battle about fibreglass vs steel, the question of gel vs lithium-ion batteries also has the potential to ignite World War III whether on online forums or at the pub… Armchair sailors and engineers alike love to talk about the mutual benefits of each battery solution. What battery bank on a long range power yacht? One of our clients who has owned several power yachts and who currently owns a new Selene has shared his experience with us… It’s worth reading his comments about the “house bank”. But we also like to know what our customers think, like or dislike. RAW files must be opened through Adobe Camera RAW and loaded into Photoshop to be accessible to Perfectly Clear.We have designed and built more than 400 vessels since 1999 and we keep a constant watch on new technologies, “greener” equipment and anything that can improve safety and comfort at sea on our yachts. Monochrome and CMYK images must be converted to RGB before using Perfectly Clear. Any image file that Photoshop or Lightroom can open and convert to this format may be used in Perfectly Clear. Perfectly Clear requires RGB-formatted images in either 8 or 16-bit color depth. Modify facial regions to provide the best corrections Manually identify faces that are not detected automaticallyĦ. Better 'color pickers' for Skin Tone and Blush adjustmentsĤ. Added strength sliders to Light Diffusion and Vibrancy for better controlī. New Color Vibrancy tool to complement our previous "Vibrancy" control (now renamed to Color Restoration)Ī. "Face Aware" exposure for more accurate auto-exposure corrections in portraits and group photosĭ. Preprocessing section for Input Looks and "Image Ambulance" for manual exposure correctionsī. Then, you can quickly export these settings to a text file - ready to be copy / pasted into your source code with our image correction SDK.Ī. This allows you to make image corrections in Workbench and tune the settings to match your style and correction needs. One of the key features in Workbench is the ability to "export to API" when saving a Preset. Perfectly Clear Workbench is an application that uses Athentech's Perfectly Clear image correction libraries and is made available to demonstrate the capabilities of the Perfectly Clear processing libraries, face detection library and to allow a quick export of the processing settings for use.
