Boat lift cradle specs needed for R21 EC

I just moved my R21 EC to Florida for the Winter and want to adapt my I beam lift to hold the R21 EC. The lift presently is set up for a 19ft Sea Pro fishing boat and will not work for the Ranger. Has anyone had any experience with the cradle dimensions to make this work? The Ranger has an interesting hull profile. I don't want to reinvent the wheel if information is out there. More importantly I would rather not do trial and error engineering on supporting the hull.
Thank you in advance..

Bob, I just moved my 21 EC off the lift and onto the trailer for the winter. Winter time depths at the end of my pier are too shallow to use the lift. I'll take some measurements at the bow and stern ends and let you know.

Karl...Thank you...That would be great.

I'm still looking for information on boat lift bunk design and measurements for a Ranger 21EC. Capt' Carl ..you out there? You said you might have the measurements from your lift. I'm real close to needing these for my lift when the ctr console fishing boat leaves in a week or so and the EC hits the water.

Bob, took pictures and measurements yesterday. I'll send the pictures in another email. The rails are spaced 40 inches apart at the stern and 50 inches apart at the bow.

sorry for the delay,

Karl

Karl,
Thank you for your reply. The dimensional information and pictures that you sent are VERY helpful.

I have a new 21EC coming and need to adapt my lift from my old 18'. I saw the post about the bunk spacing and wonder if I could see the photos, too. Htaylor@realtyplace.com thanks
