O'Day 40 Review — Philippe Briand Design, Specs and Cruising Practicalities

With a wing-keel draught of 4’ 11” (1.50 m) and an optional fin keel Draft of 6’8″ (2.03 m), the O’Day 40 typically fits most east-coast marina berths and shallow anchorages in the Bahamas, while its 39’7″ LOA and 12’7″ beam determine berth fees, travel lift straps and bridge-clearance planning for passage-making logistics.

Design & Construction at a Glance

The O’Day 40 emerged from a collaboration between the American builder O'Day Corporation and the French naval architect Philippe Briand. The hull is solid fibreglass for impact resistance, while the deck employs a balsa core to keep weight down and stiffness up. A structural grid distributes rig loads and contributes to a reassuringly stiff feel underway.

Hull Form and On-Water Behaviour

Briand's signature is evident in the flatter underbody and finer entry, giving the O'Day 40 better off-wind manners and higher average speeds than many contemporaries. The boat's form stability — with beam carried well aft — helps it stay relatively flat in a blow, reducing crew fatigue on long passages.

Performance Ratios: What the Numbers Mean

Practical Cruising: Layout, Tankage & Systems

The interior typically offers a two-cabin, two-head arrangement that suits two couples or extended cruising. The U-shaped galley to starboard provides safety when heeled, while the cockpit is deep and protective. Typical tankage for coastal cruising is around 100 gallons (378 L) of water and 40 gallons (151 L) of fuel, adequate for extended days between refuelling stops and useful when provisioning for island-hopping itineraries.

Buyer's Checklist: What to Inspect

1. Balsa core moisture: Check around stanchions and the mast step for signs of delamination.
2. Chainplates and seals: Look for water stains on bulkheads indicating deck-seal failure.
3. Keel-hull Joint (“O'Day smile”): Inspect for hairline cracks and keel-bolt integrity on fin-keel examples.
4. Mast step & compression post: Ensure no deck sagging beneath the deck-stepped mast.
5. Through-hulls: Replace original plastic valves with bronze or modern composite fittings where necessary.

Comparing the Field

Competitors in the era included the Catalina 42, Hunter 40 and the Beneteau First 405. The O’Day typically trades a touch of the First 405’s raw speed for increased interior volume and a more substantial hull feel versus the Catalina, whilst differing from Hunter in offering more conservative, performance-influenced lines.
