Do you already have the rig dimensions for my O'Day?

Most likely. Every O'Day model on this page has its own page carrying published rig dimensions (I, J, P, E), and where those are complete we can price a sail straight from them. We still confirm the measurements against your actual rig before anything is cut, because masts get replaced, rigs get modified, and published figures describe the model rather than your boat.

What if my O'Day isn’t listed?

Send us the boat and your rig measurements through the contact form and we will quote it. The archive covers production models, so one-offs, heavily modified boats and rare variants often aren’t in it. That has no bearing on whether we can build your sails.

Can you match the original sail plan?

Yes. We can build to the original sail plan, or adjust it around how you actually use the boat, whether that is cruising, short-handed sailing or racing, and around your rig’s current furling, reefing and batten arrangement. Tell us what you have and what you want from the sail, and our designers will work from there.

About the yard

O'Day

O'Day was founded in Massachusetts in 1958 by the Olympic sailor George O'Day, and built a large number of small daysailers and trailerable cruisers alongside its bigger boats. Many are still sailing and most are long overdue a new set of sails.

Models owners ask us about most often: O'DAY 250, O'DAY 240, O'DAY 280, O'DAY 302 and O'DAY 322.

Tall-rig versions

O'Day sold several models with a taller mast. On the O'DAY 34 the tall rig takes 2.8 ft more mainsail luff than the standard boat. Order from the page for the version you actually have:

Common questions

Do you already have the rig dimensions for my O'Day?: Most likely. Every O'Day model on this page has its own page carrying published rig dimensions (I, J, P, E), and where those are complete we can price a sail straight from them. We still confirm the measurements against your actual rig before anything is cut, because masts get replaced, rigs get modified, and published figures describe the model rather than your boat.
What if my O'Day isn’t listed?: Send us the boat and your rig measurements through the contact form and we will quote it. The archive covers production models, so one-offs, heavily modified boats and rare variants often aren’t in it. That has no bearing on whether we can build your sails.
Can you match the original sail plan?: Yes. We can build to the original sail plan, or adjust it around how you actually use the boat, whether that is cruising, short-handed sailing or racing, and around your rig’s current furling, reefing and batten arrangement. Tell us what you have and what you want from the sail, and our designers will work from there.

Can’t find your O'Day?

The archive covers production models, so one-offs and modified boats often aren’t in it. Send us your rig measurements and we’ll quote your sails either way.
