Just bought a 27 ODay and need to move the shroud chainplates back to inboard where they were originally mounted.I have replaced the bulkheads and will have to beef up the deck where the old plates attached.I dont have any old hardware or clue as to what the deck mounting hardware is and the spacing.The upper shroud opening is still in the old tabbing and is a good reference to its location.I measured the new locations outboard and they are all appox. 18" center to center.Does this match anyone's specs.?If anyone has a manual, blueprints,or technical specs.on this boat I would pay to have a copy.
Thanks for reading,
Todd

Hello Shemlock. See "And so it begins" page 2 for chainplate locations as I have just gone out in minus 5 degrees and aquired the measurements from YOT. I have edited the post to include these measurements. I can also E-mail you the 27 manual but the lads were unable to convert the format to post online. PM with your E-mail and I will send them to you. And so it begins thread is my complete restoration of an Oday 27 which gives a look see at just about everything I am running across and the problems/successes I am encountering. It also contains many facts on the 27 and other Oday models provided by other Oday owners. Feel free to add your own insights there as you make new discoveries.

Chainplates moved back inboard

Hi there 25,
It would be great to have a copy.Please send it to thunterww@yahoo.com Well Ive owned my 27 for a little over a month and for a boat that was in "excellent condition"it may not make a splash this year.Many problems torn step area on the deck broken tiller head torn head sail soft spots old worn out teak etc.The good news, I hope,the hull is sound mast traveler wiring head holding tank all good shape.Need all safety dock gear, some standing and running rigging.So Im closing in on a total refit but Im loving it!Im still finding holes ripped through the headliner in the aft quarter berth by a madman with a sabre saw.Its a totally different world than the one I came from. High end remodeling. I have this bug to sail and it is all consuming .Is this normal for a man of 55 to begin from scratch; the Art of Sailing??? Thanks in advance for the info.
Regards,
Todd

Hi Joe,
Wanted to update you on my progress.I did get a scale drawing of the 27 and for anybody's future reference all shrouds are 18"in. on center.I believe the fore and aft shroud chainplates have a 11 degree bend to them?Ive removed all the old bulkheads and have cut and in process of finishing the hew ones.Next is to repair the weak spots in the old chainplate areas and reinforce with over sized backer plates and custom chainplates.Joe do you have any pics. of your refit?

Ahoy there Shemlock. Huh, the slots on my inner deck skin were 17.5 inches from the upper shroud chainplate. Must of been a Monday morning boat. Anyway to the question at hand. And so it begins page 2 shows my method of reinstalling the chainplates. Since I was recoring the deck I had the opportunity to modify the chainplate mounting method and add epoxy windows around those areas. Assuming all 76 27s were constructed the same way you will find the deck outer skin 3/16ths inch thick, the balsa core 3/8ths thick and the inner deck skin. The cabin liner, which is not the inner deck skin, has some mystery material filling those 4, 4" X 10" molded in holes that when the material is removed provide access to the chainplates. My 27 had a previous attempt to epoxy infuse the core on the starboard side that was less than ideal. That is going to be recored come spring as once water is allowed into the core it readilly migrates to areas all over the place. If you find yourself in that position don't get too upset as recoring seems more intimidating than it really is. It isn't all that expensive either. Just remember, the hull is the critical part of any boat. All the rest is fluff. The hull is the thing that makes it float and that makes it a boat.

Hello, 25 Years Later
Do you still have a 1976 O'Day 27 "manual and tech specs" available to email? I recently purchased a '76 O'Day 27 and would be very interested in a manual. My boat was surveyed and is in pretty decent shape save for some leakage around the toe rail above the (port) quarter berth.
Thank you.

Ahoy 25

Joe the 17.5 may very well be the exact numbers I extrapolated from a 30 something year old drawing and came up with a 3 foot spread so 1/2 inch both sides seems to be in tolerance.It doesnt seem possible to have a 3/8 thick balsa core and have it stand up to the rigors of chainplate action.So the liner seems to be a nuisance in the fact that you cant truly anchor through it without first filling the void or creating a heavy backer plate. My sentiments exactly regarding the hull. Joe do you remove the skin replace the core feather the edges and laminate with cloth fair and paint? I have A BUNCH OF PICS. BUT DONT NO HOW TO POST THEM HERE?Have you any of your project?
Best Regards,
Todd

Hi jeferie. PM me with your E-mail and I will send it to you. It's in MS word format. The 27 toe rail screws are beyond the core capsule so other than making a mess of your hull liner the core is safe. Some pics of the recoring are on page 1 of 'And so it begins' thread Shemlock. If you need some more let me know and I can E-mail them. Check out the West Systems Fiberglass Boat Repair manual for the details. It is a very concise primer on just about all types of repairs. It's the method I am following and the info is fantastic.

I just bought a 1977 Oday 27. Do you still have a manual in Word format that you can email? If so could you send me a copy at rboozer@fairpoint.net. If not could you tell me where I might find one. Thank you very much. Ron

Hello 25yearlater
I Just discovered this web site and was very excited to see that you have the '76 27' ODay manual in tact. I purchased a '77 27' ODay a year ago and have had no luck hunting the manual down. Do you know if the '76 manual is compatible with the '77? The little bit of reading I have done suggests that they are. I would be extremely grateful if i could get a copy of it.

Hello Todd,
A fellow member suggested contacting you for specs on the O'Day 27.
I have a rudder in need of repairs and I am looking for rudder specifications.
Would you happen to have with you a scale drawing of the O'Day 27 ?
If so, would it be possible to have a copy ?
Thank you very much for your time.
Robert and Summerwind :)

Hi 25,

I became the proud owner of a 1976 27' O'day in late 2008. She was fully restored in 2005/6. Don't know if there was a problem with the deck core, but solid now and overall excellent condition. If interested, I can send you photos.

BTW, if you could email me the specs to lagune@shaw.ca I'd appreciate it.
Thanks - I look forward to seeing the final result on your thread.

I just purchased a 1976 Oday 27 at auction. I got it for a great deal, but it's missing the rudder. Would you please e-mail the manual to me at my username @gmail.com

Thanks so much.
