We recently purchased a 1982 C25 Swing Keel. We are having a trailer built and I remember seeing a drawing with dimensions on where the bunk placements go and the heights. Does anyone have a copy they can send me or refer me to? Copies can be sent to my e-mail Sailynn@jps.net
One of the guys in our club has a swing keel. He and his dad coppied another trailer and ended up with a great trailer. I'll ask him if they made up plans or just built directly from the other trailer.
I'm in the middle of the same dilema except that I'm converting a motor boat trailer to a sailboat trailer also a swing keel 25.
I saw some drawing back in April with regard to a trailer that was being built by Ben Allen at Benallen@midspring.com his drawing and photos seemed awsome, it was a trailer with roller bunks and I wrote to him.
He was kind enough to reply the following:
" Since I posted the photos of my trailer rebuild, I have switched to bunks. The roller's were deflecting the hull up to 1" in some places. Part of this is that I have not built in a pad for the keel to rest on, your bunks or rollers should only keep the boat from tipping over.
The balance of a sailboat on a trailer should be where you have 8 to 10% of the weight on the tongue for a single axle, and 5 to 7% of the weighton the tongue for a tandem axle. On my trailer, I started with 151" from the winch to the front upright.
If you have purchased a power boat trailer, chances are you will have to move the axles forward. They are normally placed further aft to compensate for the weight of the motor. If you choose to go with bunks,Champion Trailer make a conversion kit with this in mind. Their URL is:
I don't think he'll mind that I'm passing this on to you.
I've gathered from most people the importance of placing some support for the keel once the boat is on the trailer. In other words the keel must be dropped and rested on the trailer once the boat is aboard. The exact location of the bunks pretty much depends on the lenght of the trailer and where the padeye will rest. I got some measurements form a real nice guy Gary Bruner who has rollers on his trailer if you like I can e-mail you his info or you could contact him at molika@teleport.com he's a very helpful person.
Hope this has helped you somehow! <img src=icon_smile.gif border=0 align=middle>
Friends: Just sold my project boat, Suede Shoes, a swinger, to a fellow looking for a trailer...it prompted me to remember that there is a company in Bellingham, WA, called Quality Trailers that builds a sailboat conversion kit for trailers. I think they mean "fins", but they'd work for swingers, too, I am sure...I think they install the screwjack/pad dealies, but I think they'd work. I haven't ramp loaded much with that type, but I think one could.....just a thought, depending upon where you're located....They advertize the kits starting at $695.
