General Information
Designed by Allen P. Gurney.

One of the photos shows a twin-keel O'Day 27 -- does anyone have information about
this?  I have to wonder if it was a factory experiment or a custom design.

Miscellaneous information
From Mike Reilly  on 05/01/2000:

(O'Day 27 Brochure text reproduced here, brochure in too poor condition to scan)

The O'Day 27...for size and price, she really has no competition.  But still, we're making design
modifications to improve her performance and appearance.  And her value to you.

In 1975 we designed a better performing balanced spade rudder with skeg.  Less wetted area.  Better
speed.  The new keel modification lowers the ballast and improves control and stability.  Wheel
steering is optional.

Below decks are new interior fabrics and colors with coordinated table and formica counter tops.  
Enclosed head, with mirrored sliding doors.

Main cabin with folding table and storage lockers, 6' headroom.  Sleeps six.  Throughout the interior,
we've used rich, hand-oiled teak wood extensively.  Pin rails have been added in the cabin and head for
added storage.  She's the ultimate in 27' sailing yachts.  Responsive and comfortable.

For '76, we've relocated the galley aft near the main companionway.  The cook will enjoy more space
and save steps serving the cockpit crew.  Galley includes sink, water pump, family sized water tank,
recessed stove area, 4+ cubic foot ice box, and plenty of storage space.

Our 1976 Standard Equipment is almost endless, including main, jib, boom vang, 4" berth cushions,
V-berth insert, bilge pump, bow pulpit, curtains, halyard winch, self-contained head, jiffy reefing, life
lines, outboard bracket, two burner alcohol many other items to make your sailing more
comfortable...and safer.

O'Day 27...Sail Away price of $12,590. Includes main, jib, boom vang and a long list of standard

For equipment list, catalog and pricing, send $1 to Dept. 19.  Backed with O'Day's 2 Year Gold Medal

Another Press release (undated)

The new O'Day 27 sloop outperformed a whole herd of larger boats in races
during her first four days in the water.

At the Beverly Yacht Club annual regatta held at Marion, Mass. in August,
the O'Day 27, skippered by O'Day Vice Pres., Jim Hunt, was first overall
following a first and second place in two days of competition.

Each race was over a 20 mile course in light to 12 knot winds.

The smallest boat in the fleet, the O'Day 27, won the first race by a considerable
margin. The following day, the O'Day boat placed second, beating every competitor
boat for boat except for a 44 footer.

Hunt's crew included his wife Ellen and three children, and Bourne and
Ruth Knowles.

The new Gurney designed sloop from O'Day sleeps six and will be displayed at
boat shows in Newport, Annapolis, Stamford, and at Atlatic Highlands this Fall
and at the New York Boat Show next year.
