The Jeanneau Sun Odyssey 40 and Sun Odyssey 40.3 are different boats that share a name, a heritage, and — unfortunately for used buyers — a fair amount of confusion in the market. If you are shopping for a used Jeanneau in the 40-foot range and you have seen both models in your search, this comparison will help you understand what you are actually looking at and which one is worth pursuing.
Brief History: The 40 and the 40.3 Are Not the Same Boat
The Sun Odyssey 40 was produced from approximately 1999 to 2002. It was designed by Daniela Messina — a capable if conventional production cruiser for its era with an IOR-influenced hull form, twin-cabin layout options, and solid overall performance for a family cruiser.
The Sun Odyssey 40.3 replaced it from approximately 2002 to 2006. The design changed meaningfully: the hull form was updated, beam was carried further aft (a shift Jeanneau was making across the entire Sun Odyssey range during this period), and the interior layout was revised for improved volume and flexibility. Both boats are approximately 40 feet, but they are separate hull designs with different characteristics. A survey that covers one does not substitute for surveying the other.
Sun Odyssey 40: What You Are Getting
The Sun Odyssey 40 is a product of its era in both positive and challenging ways. The narrower beam aft compared to the 40.3 means a more traditional sailing hull — slightly more alive underway, slightly less volume below decks. The Marconi ketch rig option available in some build years makes it interesting to buyers who want offshore capability with a manageable sail plan.
Below decks, the standard layout provides two double cabins, a center saloon, and a single head with shower. The nav station is proper and well positioned. Headroom in the main saloon is typically around 6.0 to 6.2 feet depending on variant.
Structural concerns to prioritize when surveying a Sun Odyssey 40: osmotic blistering in the hull gelcoat (common in boats from this era kept in warm water), the chainplate area (the deck fitting arrangement from this period has a known history of water ingress if not maintained), and the keel-hull joint on any example with a grounding history. These are not disqualifying issues in a well-maintained boat — they are inspection priorities.
Sun Odyssey 40.3: The Upgrade
The 40.3 is the better boat for most buyers evaluating used Jeanneaus in this size range. The revised hull form provides better stability at large heel angles, more interior volume through the aft sections, and improved ergonomics at the twin helm stations that became standard during this production run.
The 40.3’s cockpit is a direct improvement over the 40’s. The twin helm stations provide better visibility on either tack, the cockpit volume is generous for four to six people at anchor, and the storage compartments are better organized.
Common survey findings on the 40.3: the mast boot seal around the keel-stepped mast deserves close inspection — water ingress through the boot has been reported in boats without regular maintenance. The genoa track adjustment mechanism on early 40.3s can corrode in salt-water environments. The battery installation location under the nav station berth tends to collect water — inspect the battery boxes and bilge pump operation carefully on any example.
Pricing in Today’s Used Market
The Sun Odyssey 40 in good condition trades between $50,000 and $80,000 depending on year, equipment level, and geographic market. The Sun Odyssey 40.3 in comparable condition runs $70,000 to $105,000. The 40.3 premium is justified for most buyers. The improved hull form, better cockpit ergonomics, and more recent manufacture make it the stronger choice. The gap has also compressed over time — both model years are now 20 to 25 years old, and condition matters more than model designation at this stage.
Which One Should You Buy?
For most buyers: buy the 40.3 if you can find a well-maintained example in your price range. The improved hull and cockpit are meaningful, and the additional years of production mean more parts availability and better survey experience with common failure modes.
The Sun Odyssey 40 is a legitimate choice for buyers on a tighter budget who find a well-surveyed example, or specifically for buyers who want the ketch rig option for offshore use.
For both models: do not skip the marine survey. These are 20+ year old boats and the difference between a well-maintained example and a deferred-maintenance boat in cosmetically acceptable condition can be $30,000 to $50,000 in undiscovered work.

Frequently Asked Questions
Is the Jeanneau Sun Odyssey 40.3 a capable bluewater boat?
With appropriate preparation — storm sails, jacklines, upgraded life raft stowage, and a properly serviced rig — a well-maintained 40.3 is a capable bluewater boat. Many 40.3s have completed Atlantic crossings and Caribbean circuits. The Jeanneau build quality from this era is solid.
Where can I find used Jeanneau Sun Odyssey sailboats for sale?

What survey items should I prioritize on a used Sun Odyssey 40 or 40.3?
Hull blisters, chainplate condition and deck integrity at the chainplate penetration, keel-hull junction, mast boot seal, battery box and bilge condition, and standing rigging age. Both models should also have their fuel tanks inspected — aluminum tanks from this era can develop internal corrosion that is not visible externally.
