Can anyone explain how much weight should be on the keel and how much on the bunk supports. How would you figure out how much you have on each.

Also, when I set the bunk pads, if I miss the initial setup a little bit is it better to have the bunks too high or too low?

90-10, the pads just keep it from falling over.

Terry,
Thanks. So if I read you correctly, your front pads are set 9 in higher than the center pads, and the rear pads are 1/2 in lower than the center pads. Interesting, I would have expected the rear pads to be a little higher than the center ones. Our trailer is for a fin keel C-25. That's why I was more concerned with front-center-rear relationships.

 The hatch cover was made by these guys,
http://shop.catalinaowners.com/detail-hatchcovers.htm?fno=20&group=568
Have them look up Frank Hopper's job. They are custom so the measurements are critical, I believe we got it right on Terry's.

The wing was firmly on the keel rest. The bottom is not flat.

Frank,

Thank you for the link to the hatch cover. I'll try to give them a call tomorrow.

Gary,

I took a few photos for you today of Wicked Escort on her trailer.....

The bow is 48" astern of the very front of the trailer, and as you can see, the mid point of the keel is pretty much between the two axles.

Sorry the tape measure is a little indistinct....if there are specific measurements you'd like, let me know and I'll provide them (for the next week or so she's just outside the house, on my driveway).

Thank you Julian! I appreciate you taking the time to take these pictures.

In pictures 8,9,& 10 are you measuring from the ground or from the board under the keel? Can you measure the length of each of the vertical supports on one side from the top of the keel support board to the top of the metal tubing not counting the wood bunks (just the metal portion of the uprights)? Also, could you measure the length of the keel from the top of the keel support board to the bottom of the boat at a point where the flat portion of the boat just begins (approx. 2" from the center side to side of the keel)? Looking at the last picture above a point just where the radius from vertical to horizontal ends next to the keel?

What is the measurement side to side between the uprights?

Thanks again for taking the time to take these pictures!

Gary,

Photos 8, 9 and 10 are measured from the ground (the width of the tape measure holder is 3").

The vertical supports for the bunks are 1.75" square tubing. The heights of the tubing only are:

front: 21"
center: 17"
rear: 21"

all measured from upper surface of the keel support board.

The side to side dimensions of the vertical supports (measured to the outside edges) are:

front: 39"
center: 56"
rear: 63"

The vertical distances from the upper surface of the keel support board to the flat portion of the hull are:

center of keel: 16"
rear edge of keel: 18"

Hope this helps. Let me know if you need more.

Thank you Julian! this is exactly what I needed. With your help and Jeff's I should now be able to get a good initial setup on my trailer.

I may have to hurry again as I see there are now two areas in the Carribean that are expected to develop into storms in the next day or two.

Photos 8, 9, & 10 indicate a 1" difference in the front and rear heights of the bunk, which is consistent with the drawing in the owner's manual for a C-25 cradle. It looks like the bunk height at the middle support is about 5" to 6" shorter. I can work with that.

I don't have time to read the whole post but I have an 89 wing and I bought a new trailer when I bought the boat. One thing to rry if you have the luxury is to take it to a boat yard and have them haul it and set it down on the trailer. Adjust the trailer, then have them disconnect the lift. I was lucky but I picked the boat up at a boat yard and they let it hang there while I backed the trailer under the boat. I adjusted everything up to the boat. They set the keel on the center until the trailer had the load. Then I adjusted the trailer to the boat. The only issue was trying to guess at the tounge weight (how far for and aft). I had it pretty close. Did it by eye and got it about right. The first time I launched and hauled I had to adjust the winch stand a little but it wasn't too bad.

Good Luck

Well 11 months after buying a trailer for my boat (just before Hurricane Ike hit) I'm finally going to attack setting the bunks to fit my boat. The yard is going to pull my boat with a Travel Lift Wednesday afternoon. After pressure washing the bottom they're going to set it on my trailer and help me get it set in the proper position and are allowing me all night to get the bunks adjusted and bolted in place. The next morning they will completely release the straps so I can make sure everything is adjusted properly. They will then set me back in the water and hopefully I can sail the rest of the week!

According to the yard foreman the keel should support 60% of the weight and the bunks 40%. Apparently the lift has scales built into it so they should be able to tell me how much my boat weighs. My question is, how will I know when I have the proper weight on the keel and bunks? I'm thinking they can weigh the boat as they are lifting it and then lower it onto the trailer until 60% of the weight is sitting on the keel. I could then adjust the bunks tight against the bottom of the boat with some floor jacks and then drill and bolt the uprights into place.

Will this method work?

To make the process faster I was planning on setting the bunks using the measurements above provided by Julian and Jeff.

Any thoughts or suggestions?

BTW... My trailer was built for a Hunter 26 or 260 and the uprights are 1-1/2" X 1/16" or 1/8" wall square tubing. My new/longer uprights are 1-1/2" square tubing but I went with 1/4" wall. Any thoughts on whether this will be strong enough to support my C25?

The Hunter 260 is a water-ballast boat, displacement 5000 lbs with ballast, and about 3000 lbs without ballast. Comparable weight for the C-25 WK is also about 5,000 lbs. It seems logical that the trailer would have been designed to hold the 5,000 lb load, say 5,500 lbs with gear, at least for the time it takes to drain the ballast tank. You should be okay. Have you tried to contact the mfgr.?

How are you putting the pics in your post? I have a boat trailer question, but haven't been able to copy the picture into the post..is there a specific way you are doing this for this forum?

Click on Association Forum in the listing at the top of the page on the left side, then Testing Forum under Information for first time Users, then the thread on posting pictures. You need to first upload your pics to an independent site like Shutterfly, then link them to this forum.
