I’m looking at purchasing a 27 foot 1959 constellation and modifying a current trailer that I have fourth older 30 foot boat that I no longer possess.
I am curious if anybody has any pictures of their commander sitting on a 27 to 30 foot boat trailer that I might be able to see a picture or two so that I can see some things to take into consideration with bunk place meant and allow allowing proper clearance for shaft and prop.
I’m looking at having the two bunks as far outward to the Chinese as I can get them and an additional two bunks along the keel as close as I can get them.
Any pictures you might have or considerations I should take into account would be very helpful.
Thanks in advance
Below is a picture of the trailer I’m in process of modifying

I can't find the posts but there have been 2 or 3 at least. I believe Clyde Caron had one for his 31. I think the trick is to get good contact support fore to aft both outside the shafts and inside. Good luck
From SuperDisc Archives:
Jim Frens also stated later: The bunks on mine are not parallel. The 39" spacing is at the bow end. At the stern end it's 46". Never noticed that before.
My bunks sit 7" above the axle tubes and cross members. That allows an inch or two or three between the keel and trailer.
My bunks are raised slightly, esp. stern end, to allow hull to clear the trailer fenders
Holy smokes… Thank you both so much!
Mark, Having a wood boat myself on a trailer, be absolutely sure the bunks extend all the way to the transom. If they don't, the bottom will hook and the bow will constantly plow. Good luck
@ Mr Schriber...thanks. That was a concern/goal for me as well. My supports will be 18 feet on the inside along both sides of the keel and 12 feet along outermost edge.
When you say outermost edge, do you mean the chine
I do indeed
Well, this is what I’ve ended up with.
The pole at the front will have a bow stop that’s two 12 x 18” pieces of carpeted covered wood that both swivel approximately 20” inches apart just to get the front of the boat something to rest against and be pulled against.
All the bunks have a certain degree of swivel in them to mold to angles of the bottom of the boat.
It’s a slow as I can get it on this trailer and I think it’ll work out.
I’ll post an update when I’ve got the thing loaded and all set.
It’s two 7000 pound axles. 28 feet from the furthest away piece of the bow rest to the back of the bunks
Mark. Looks really good. Nice work. Give us a shot of her loaded
Just wanted to say thanks again to everybody for all the help and suggestions… Towed like a dream 750 miles.
Had to make a couple of adjustments on the trailer for the keel support and add some temporary height adjustment to the chine support.
When I get her back in the water, I’m gonna adjust the trailer for the long-term.
