I meant an aluminum dual axle trailer. I have the top to keel dimensions but still need to know how much higher those dimensions will be when the boat is sitting on the trailer. I am hoping it only will add another 15 inches from the ground to the bottom of the keel.
I second that Bondo. I can't see the bunks only being 15" off the ground. Consider that the trailer you will need will probably have 15" wheels on it. Then add in the height of the sidewall (multiply it by two) and you've got at least 20 inches. The bunks will be higher than that, or the fenders that covered the wheel would hit the bottom of the boat. Now the keel of your boat will be lower than the bunks, but not by too much. Anyone have a guess here?<br /><br />Thomv, if the difference in height between your boat's keel to top measurement & garage door opening is only 15", I don't think you're gonna make it.
The diameter of 15" trailer tires is about 28". Half of that puts the center of the axle at 14" above the ground. Many trailers (mine included) have "drop axles" which are lower in the center than at the hub ends. This allows the boat to sit lower on the trailer. Also, torison axles will place the trailer frame closer to the road than leaf springs. The fenders are outside the boat's width at that point of the hull. <br /><br />My boat's covered with snow right now, but my recollection is that the bottom of the hull is 15" or less from the ground, possibly as low as 12".<br /><br />The only way Thomv can know for sure is to measure it and it's going to be a close fit at best. There are companies that make "custom" trailers and they may be able to make one that puts the boat lower to the ground than usual.
