The day before Ike struck I was able to purchase a trailer that I can modify to hold my 1989 C25 Wing Keel. Can anyone provide me with the measurements I need to set the bunks so I can properly support my boat (I contacted the manufacturer (Magic Tilt) but the person I need to speak to is on vacation).

It's currently setup for a Hunter 26 or 260.

Well, I just heard back from Magic Tilt and they don't have any spec's on the C25 so they suggested that I just put the boat on the trailer and adjust the bunks to fit. Does anyone have any better suggestions or rough estimates on the height of the bunks I could use to get in the ballpark before I try loading it on the trailer? Catalina could only give me the diagrams on the cradle for the C25/C27.

If you go here... http://www.catalina-capri-25s.org/tech/tech25/tt011.asp there is a diagram with the measurements that I used to set up a trailer for a swing keel. I think I read that the wing was about 2" deeper.

Isn't that the lofting process? You determine the distances of each point from the line drawings, or from direct measurement of the half hull model.

Or might you pull it, jack stand it up with the trailer in place, and adjust you boards accordingly?

These are the same drawings that Catalina sent me via email. I guess I'll make my initial adjustments based on these drawings. After they get the boat positioned properly on the keel board with the Travel Hoist I can use a floor jack under each support leg one at a time to snug up each bunk.

Jeff,

If you have time and don't mind that would be really great! Please don't go out of your way. I know I'm really pushing my luck now but if you do have time would you possibly be able to get a few pictures also?

Thanks in advance for your help!

Will do, I was thinking I could take a measurement back from the bow roller to about where the wing sits, then take a height to a board across the bunks there and several feet in either direction. I will try to take some shots of the measurements being taken. My trailer also has vertical guides for the wing...

I will help if I can. I have an 87 wing. My trailer is a trail-rite with 4 roller bunks. I am not sure that the placement of the roller bunks will help but I will try to do that today. I would start with where the keel is over the axcel and use that as my refrence for every thing else. It looks like a nice trailer.

Thanks BengeB.

I think I got a good deal on it. It's a 2003 year model and I got it for $1500.00. They were originally asking $2,250.00 but with Ike coming I think they were ready to move it quickly. It doesn't look like it was towed much.

Gary, OK, I am going to try to relate these measurements as best as I can. I started by creating a Reference point at the approximate center of the keel location on the center board. It is 13'10" aft of a point directly under the Bow roller (my roller is 58" above the plane of the Keel board, you may have to adjust that number if your roller is significantly higher or lower) I then made two more reference points, 3' and 6' further aft of what I will call the CL ref pt. I also made two more 2' and 4' Forward of the CL ref pt. I then laid a board across the bunks at each point and measured the vertical distance to the bottom of the board at each of the points. I also measured the horizontal distance (from cl to cl of the 2"X6"X12' bunk at each location in case yours are different.

Forward ref pt (4' forward of the CL ref pt) Height 23", Width 37"
Next pt aft (2' forward of the CL ref pt) Height 21 1/4" Width 39.5"
CL ref pt. Height 20" width 41.5"
1st aft pt (3'aft of the CL ref pt) Height 18.5", Width 45"
Aft ref pt (6' aft of CL ref pt) Height 21" width 45"

I also have three sets of 15 inch tall Keel guides to center the boat on the trailer. the forward set are at the CL ref pt. they are 28.5" apart (I would like them about two inches closer together if I had a choice) the others are 31" and 33" at the back of the trailer if you decide to try that. I left my camera on the boat today, I will post the Pictures (although I do not think it will help too much) when I get it back home this week... Good Night and Good Luck... Jeff

Wow Jeff, I really appreciate your taking so much time to get the measurements for me! I really, really appreciate your doing this for me!

I believe I understand what you're saying. I assume all of your measurements were made from the top of the keel board? I'll have to look at my trailer and layout your measurements.

Looking at my pictures above where would you say the keel should be centered? I'm thinking approx. centered between the axles.

This trailer was built for a Hunter 26. I will most likely have to move the bow stand back 12"-18".

If you have pictures they might help. What brand of trailer do you have? Do you have a trailer model #?

Thanks again for taking the time to get these measurements. They will really help me get this trailer setup.

Mine is a Shoreline Trailer (they are out of business, so you won't find anything from them. I had this picture from last year. you can probably get an idea of Keel placement. it is centered between the axels.

Thank you Jeff! Your trailer looks very similar to mine. Are the uprights that support the bunks on your trailer square tubing or C-channel?

Jeff,

Can you clarify a few things for me?

Were these measurements made from the top of the board the keel sits on to the bottom of the board laid across the bunks or are these measurements the length of each of the supports from the top of the C-Channel to the bottom of the board laid across the bunks?

The reason I'm asking is I thought the keel was 2' 10" long and it's not adding up in my mind (not a big surprise)!

Hey Gary, Good looking trailer. You may look at a way to make your rear guide post removable. My last boat was a Hunter 260 and it carries a 9" beam. That made the guides way to wide to tow with comfortably. I was able to cut my guides and put a sleeve in then that made it possible to use pins for the purpose of launching and retrieving. Then I removed them before hitting the road. I never seemed to be able to keep it in one lane, and I tow with a duelly. It will also make your width look smaller to law enforcement. I'm thinking you'll be somewhere close to 10' with the guides in place.
Good Luck

You're probably correct about the width. I have to be exactly in the middle of my lane or one of the guides is on or over the line.

I hadn't thought about removing or adjusting the guides. I did notice there are only two bolts on each side that hold the guides in place. Should be pretty easy to adjust or remove.

Do you remember what the draft was on the 260? Was it a wing keel or retractable keel/centerboard?

BTW, thank you for the pictures of the forward hatch cover! I'll get one of those made this winter.

I may be in Denton the last weekend of October. Maybe we can get together for a beer one afternoon.

Gary, the Hunter was a swing keel and the draft was 18 inches I think. Sorry I know that is no help for adjusting your trailer. My trailer for my C25 is a lift off with 3 pads on each side. I never measured anything when the boat was on it. I did notice that the wing did not sit on the support board. It was about 1/2 inch off the board, at least that's how it looked.

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.

Well now I know. I was to much a chicken to stick my fingers under there and see. By the way Frank, took my mom (80 yrs young), and we had some wind finally!!! We were doing 5.5 to 5.8 knots under head sail alone. I think mom was a little nervous but I was really pleased. She handled great. Just wanted you to know, THANKS!!! I know, you already knew that!!!

Terry, you said you have a C25 trailer with 6 pads, 3 on each side. Would it be possible for you to measure the distance from the bottom of your pads to the trailer frame and the distance between the pad posts. Our trailer is a C25 trailer and also has 6 pads. I'm interested primarily in the differences between the forward and aft pads compared to the center pads since my center ones are sort of pre-set. Example: Your forward pads are set x" higher than the center pads and the aft pads are y" higher than the center pads.

David, here is the measurements you ask for. Both sides were the same, as they should be! All the pads measured from the top of the frame rails to the center of the top of the pads. Front measurements, 24 1/2 inches, center 15 1/2 inches, rear 15 inches. Hope this helps. Good luck

Gary, Sorry for the long delay, I was out of town (Took the boat to Lake Powell for a few days, a little hairy) The measurements were from the bottom of a board laid across the bunks, to the top of the board the keel sits on,

hope that helps

Jeff,

Thank you for the pictures. This definitely helps me understand the setup.

Now we need a log and some pictures of your trip to Lake Powell. At least you live close enough to at least think about making the trip.

All we have to look at is polluted water, refineries, unloading cranes at the port, and flat ground. Oh yeah, sunk boats and damaged marinas.
