Jeanneau Sun Fast 20 Buyer's Guide
The Jeanneau Sun Fast 20 is a 21-foot pocket dinghy built from 1993 to 1999, one of the first Jeanneau yachts produced in Poland under a Polish designer. On the used market it attracts sailors who want a light, trailable racer-cruiser for closed water rather than a volume-forward weekender, and its shoal 25 cm draught with high centreboard defines both where it can go and how it is stored.
Layouts on the Used Market
The boat’s interior is open by design: no bulkheads, a maximum headroom of 1.38 m, and four berths made up of a double bow spike plus two side benches that serve as the saloon. A mini galley block is standard, and a chemical toilet was a factory option rather than a given. The cockpit runs almost half the deck length, which is generous for the class, while the engine sits well away from the helmsman — a layout quirk that makes moving aft to swim or step below slightly awkward but keeps exhaust away from the crew.
Equipment and Common Upgrades
Fittings on these boats are basic, so upgrades tend to follow the boat’s weak points. The original sail set was poor quality and is the most common replacement, with a new wardrobe and an asymmetrical 25 m² spinnaker restoring the boat’s reaching performance. The self-steering solent is not easy to adjust, so a revised tack and sheet arrangement is a frequent owner improvement. Rigging renewal centers on the halyard sheave, a named wear point. Beyond those, buyers should expect little factory equipment beyond the mini galley and optional chemical toilet.
What to Inspect
The externally bolted iron ballast slab is prone to corrosive attack and the junction where hull meets ballast often needs attention, so examine that seam and the bolt heads closely. Check the halyard sheave and any original rigging for wear, and confirm whether the sails are original — if so they were already poor and will require replacement. The daggerboard would have deserved 40 or 50 kg more weight, a design limitation rather than a defect, but its trunk and pivot should still be sound.
Availability and Buyer's Takeaway
These boats typically appear in Switzerland, the United Kingdom, and Austria. For a shopper, the checklist is short: confirm the ballast joint and bolt corrosion status, budget for sails if original, verify the halyard sheave and basic fittings, and decide whether the shoal centreboard layout fits your trailering and closed-water plans.
