Dimension questions
« on: February 09, 2018, 12:20:19 PM »
TGIF, I am starting to put together some prints of a 28' Prince Rupert and I need some help with a few dimensions. I have attached a side view and a view of the transom and a cross section view amidships. Does anyone have the correct dimensions to compare to the ones on the attachments? I made these drawings by scaling the drawings in the plans and using dimensions that I could find in the plans, I'm not sure how close I am. I am trying to make an educated guess on the trailer dimensions. I need help on the axle location and the tongue length.

Thanks

You've got a lot of dimensions in those drawings ... which ones, in particular, would you like me to verify?  Somewhat obviously :), I have the 3D CAD models and can measure anything you'd like....

Brian,
I am interested in verifying the dimensions on the cross section of the amidships that I have on my attached pdf print, the bow eye to transom and the CG dimension. Also, would you have a ballpark dimension on an average tongue length, from the bow eye forward, and the axles from the transom? I apologize if I am requesting too many dimensions, if so, just tell me to slow the Hell down and ask for a couple at a time! :) But seriously, I appreciate any help that you can give me.

Doug

Doug.. FYI, I expect to double check these dimensions this weekend, probably Saturday morning early... thanks for waiting :)

1. Cross-section at amidships (about 12' forward of stern on 26 ft hull, about 13' forward of stern on a 28' hull) - SEE ATTACHED

2. Bow-eye to (bottom of) transom:  23' 5" on a 26 ft hull, about 25' 5" on a 28 ft hull

3. Center of gravity on a 26 ft hull is about 9' forward of the transom (measured from where waterline intersects the transom at about 3" above the chine).  For a 28 ft hull, the CG is approximately at 9' 8" forward of the transom.

4. Average tongue length on a trailer - No clue.  I would look at 4000 to 6500 lb capacity dual-axle trailers online and contact the manufacturers.

5. Distance from transom to center of axles - No clue.  Same answer as #4 above.


Hope this helps!  I made a new drawing that'll help people find and fit trailers to the boat ... see attached.  (I'll add it to the plans set eventually).
