This is very "true". But everyone in small craft should just stick to magnetic courses from the get go. All teaching schools from Mass Maritime to the Mom and Pop navigating classes will always make you convert your course to true. They do this for only one reason. Because the USCG wants it that way when they test you. But on a small boat you will never use this. Start it and keep it in magnetic, then you won't make a mistake.
On the big ship we always use True, because we have 2 gyro compasses that cost tens on thousands$$ and very accurate.
