Before I start I have searched and read many helpful posts about getting a sailboat on a trailer with that said I still have a couple of questions. I have a 1975 Oday 25 shoal draft keel sailboat. As other people have asked what is the easiest way to get the boat on the trailer? My trailer does not as yet have a winch on it but does have six bunks. The trailer when perfectly level is 18.25 inches to the top of the board that the keel rests on and the draft is according to specs 2'3". So when the front of the boat is as far forward as it can go and resting on the forward bunks the trailer from that location would need to be at least 46" deep to allow it to float on to the trailer. I have installed a (removable) depth guide at that location so that I know how deep the trailer should be so that the boat will float onto the trailer with out hitting the keel resting board. After securing the bow with a cable strap I then can pull the boat slightly out of the water and let it settle on the bunks. After it is out I am going to add a winch and guide boards to help guide the boat onto the trailer in the future. Thanks rbone for the recent specs of the width etc of the keel. Does anybody have any suggestions and am I thinking about this correctly? Thanks for any help.
Steve, I will reply with by experiences and suggestions on trailering sailboats and I am sure there will be many others that will as well.
First off the boat we currently have is much larger than yours but we have been loading and unloading sailboats of different lengths (26, 33 & 41) for years so the equipment and procedure is about the same.
The first item you already mentioned. You need a keel guide to bring it center. Second you need a keel stop to stop the boat when it is far enough onto the trailer. Lastly I strongly suggest you use what I call "goal posts" on the trailer so you know where the trailer is in relation to the boat. I have included pictures of the trailer I built for my current boat. The first one being the keel guide and the second one showing the goal posts and their location relative to the bow and stern of the boat. We use 1-1/4" pvc pipe. The aft set has a depth marked on it so you know when the trailer is deep enough.
The procedure is pretty simple. Back the trailer in until the water gets to the mark on the stern goal posts. You then know the keel of the boat will clear the trailer. Bring the boat onto the trailer by aligning the goal posts with the boat. For ours the front two will line up with the bow roller and the stern two will be parallel to the helm. Once the keel strikes the keel stop (the trailer will move a bit) have the driver pull forward slowly and this keep a little forward pressure on the keel stop since the boat will try to slide back. Once the boat is on the supports shut down the engine and have the driver take you up the ramp! No need for a depth finder.
Hope this helps and Good luck!
