Interestingly I don't think I know my boats nickname type... anyway, why the boom has a 2 foot adjustment on the mast, this confuses me on sail measurements. My sink don't drain and it pipes down into the floor and disappeared.. there's a hole in the floor in front of the toilet that has a tank there with wires, pump tanks? another one in the bow no wires, how would one fix this floor tank, the hole is the size of a softball ? I can't even see the pump. I read that people have a centerboard that moves, mine does not... why ?
76 oday 25 just bought im green some questions pleas

You have a bit of work to do....but those are great boats - I am in the process of rehabbing a 25 from the hull in right now- highly suggest "This Old Boat" by Don Casey- the bible of rehab...$45 and worth 200.
You REALLY need the coast guard basic seamanship course also- if that gets you going, then the advanced navigation course. Lots of fun.
You have a fixed keel, not a "shoal-drafter" -both are good, the fixed just keeps you in slightly deeper water. Keep in mind that the rudder usually is deeper than the keel.
If your "holes' are plastic lined, they should be changed out for bronze or Marelon valves. The holes are called "through-hulls".
Head configurations vary widely. Generally speaking it's not PC to pump overboard at all, , and never within 3 miles of the coast. Lots of coastal cruisers use porta potties, and pump out when deeded.
Post some more pix!
And don't get discouraged. You really do have a J-O-B here, but the satisfaction of getting it done is outstanding.

Yes, I got the don't pee in the harbor from mom. She can read the nautical charts but that won't keep you off a sand bar. Still looking for " where does my sink drain? The pipe goes into the floor and cannot see it come out some where. And still need help with mast sail measurement and reasons why. The boom has a 2 foot up and down adjustment on the mast, yes I can guess but your better at this.. no ?
Its a boom downhaul. Works like a cunningham. Popular back when your boat was made but not anymore. Mainsails for O'day 25s are standardly sized; I'd just look up the measurements and order/find one based on that.
thanks, but im making my own sails
I love the sailor words like downhaul, to guess, it means push down on it to tighten the sail...which petty much means stretch it Cunningham... these are all brit terms, don't we have our own boat language ? I'm good here... I figure sink just plugged and I'll run water though it and see where it comes out. Thank you again sir. Just me Oliver
Welcome Oliver,
The O'day 25 is a great boat. Pretty sure you will find the galley sink drains via a thru hull fitting and has a gate valve to shut it off. At lease it should have a valve and if it doesn't you should install one. Should be visible under the sink. If you have an ice box next to the sink like mine, that drains into the bilge.
The head sink has a hose that goes out the side of the hull above the water line.
Does your mast have a black line on it about the middle where the boom slides up and down? That is your where the boom should be when things are adjusted well, I believe. Mine does and so does the end of the boom. I think it has something to do with making sure the sail is not oversized if racing?
Check out http://sailboatdata.com/viewrecord.asp?class_id=646 for more info on your 25. that site will give you the sail measurements also.

Excellent, I will look for any black mark. Guessing not there. Yes frig next to sink, that's the one that is plug, it gives no tail of where it goes. And by the way... is the frig ac or dc ?
Not a frig. An ice box. Made to hold a block of ice with your food on top. Ice melts and drains out the bottom into the bilge. I only found where the hose went by sticking my phone into the bilge and taking photos in blind spots.
The design doesn't make much sense to me. I want my bilge dry, not wet. I use the ice box for storage and carry a cooler for my cold stuff.

In my 77 the ice box drains to a "Y" that connects to the sink in the galley. It then goes to a thru-hull out the bottom of the boat. This is a good book for starting out too;

EDIT: And she is a 25 as the 26 wasn't made until 83.

ok this sounds lime mine
Ok so your saying there's a hole in the bottom of my boat... not good big grin... heavy rain today stopped me from more investigate work and pics. Im guessing my sink is plug with crap because the valve shut off is there in plain site, and it meets with the ice box drain and dumps into the bilge. I do not remember seeing a drain in the ice box, must be small on the side some where. This boat sure is heavy for its length, almost 7000 lbs, that's like way over three 1975 fleetwood Cadillac's... I have no anchors, what size and kind do I want ? And rope length - type

The hole is below the water line, yes but... think like a straw in a glass of liquid. The dry weight of an O'Day 25 is 4007 pounds according to Sailboat Data. Link to that info is posted above in another thread. So if you add gear and a couple people, you can push 5K, probably. As for anchors, there are all sorts of ideas on that. Here's one;
http://www.boatus.com/boattech/casey/anchors-and-rodes.asp
A hole in the bottom of my boat... great, yes, I will study more. Back to this..Design DisplacementInboard, 6,950 lbs. (3159K)Ballast 2,230 lbs. (1012K)Ballast with shoe 2,430 lbs... what's a shoe for, yes, I could ask the internet but have not yet. And the 7000 lbs must mean when it's full of water, why would I need to know this? How many big people I have on board.
Thanks for the great link and answering questions like real people, it's good to know your here. I love this ... No anchor ever dragged because it was too big. Big grin ... I still don't know what a shoe is... and what's it doing in my boat....
You are quoting the specs for the O'DAY 27, not the 25.
The "shoe" refers to an option on the 27 to add depth (and weight to the keel), some 27s had deeper keels that the 4' standard fin keel. This gave them greater stability and better ability to sail closer to the wind. Draft was 5' on these deeper keel 27s. (this was the 1973-78 O'DAY 27, not to be confused with the later, 1986-89 O'DAY 272 and 272 LE)
Is your 25 the Keel/CB model (shoal 2'3" depth keel with a centerboard that retracts into it) or the deep-fin keel model? You mentiion not having a centerboard, is htat because you have the Fin-Keel model? Or do you have the K/Cb model and it seems to be missing the CB? The 1976 models and later with the K/CB had the Centerboard pendant (control line) located at the forward end of the cockpit on the forward bulkhead of the footwell. Early 1976 and all 1975 models of the K/CB had an aluminum post in hte center of the cabin (under the table) with a crank on it to control the CB.
Someone mentioned about hte rudder being deeper than the keel, that is only on the K/CB model, obviously on the Fin-Keel the rudder still only goes about 2'5" into hte water even though the keel is 4'6" deep.
I've added some pics to help, even found one showing that black lline on the mast that was mentioned.

Yes, I now realize that I have a 27 oday owners manual, mines a 25 I believe, not good. I added a couple pics. I have some more questions but I need to upload more pics first. Did these boats, the 25, ever have a inboard motor ?

Yes, an inboard was an option most years. Original (1975-76) option was a 6 or 7 HP VIRe 2-stroke gas inboard, later (1977-81?) this was changed to the OMC "ZEPHYR" 15 HP 2-stroke gas saildrive (with outboard-style lower unit installed through hull) this engine was actually based on hte 35 HP Evinrude/Johnson outboard powerhead. Finally, for hte 1982-83 models the option was a 7.5 HP Yanmar Diesel.
Some boats had inboards added (or updated) later. Including a few boats with Diesel saildrives (Volvo-Penta or Yanmar) and a few that added newer gas saildrives using a HONDA outboard powerhead (8 HP).
The 25 pictured below is a 1976 model that I think had the original VIRe gas engine replaced by a Yanmar Diesel. The pictures of the VIRE engine below are actually in an O'DAY 27, but they were the only pis that I could find of a VIRE.
D&R Marine sells O'DAY 25 Manuals, or at least the original rigging sheet ($10 including shipping last I heard). Pretty basic, but that was what came with the boats. I have created a more updated/expanded version that I can make a copy of.

yes, good pics, this pic is
This pic is what my boat had, it's been removed but you can still see all the structure. I read there fumes would make the family sick before they left the harbor... glad it's gone.
