Beneteau
First 18
The Beneteau First 18, originally born as the Seascape 18, is a quintessential modern sportboat that bridges the gap between dinghy sailing and keelboat cruising. Designed by Sam Manuard, it features a wide, flat-bottomed hull that planes easily and a swing keel that allows for beaching or easy trailering. Positioned as an entry-level performance boat, it appeals to young families and sailors looking for 'pure' sailing without the complexity or cost of a larger yacht. It is widely considered one of the most successful small sportboats of the last decade.
When surveying a First 18, the swing keel mechanism is the primary focal point. The winch and cable system should be checked for wear, and the keel trunk should be inspected for any impact damage or stress cracks from groundings. Because these boats are often trailered, the gelcoat on the hull bottom and the transom should be checked for 'trailer rash' or star-crazing. The carbon fiber mast is a high-value component; inspect it for any UV degradation or hairline cracks, particularly around the mast hound and forestay attachment.
Build quality is robust for a boat of its weight, utilizing vacuum-infused glass and polyester. The interior is simple, providing just enough space for two people to weekend-camp, which means there are few systems to fail. The market context for the First 18 is excellent, with a very active class association and high demand on the secondhand market, making it a safe investment for those looking for a fun, manageable, and highly liquid asset.

Buyer FAQ
- Can the First 18 be towed by a standard family car?
Yes, with a towing weight of around 600-700kg (including the trailer), it is easily manageable for most small to mid-sized cars.
- How stable is the First 18 for beginners?
It is very stable for its size due to the wide beam and heavy swing keel, though it still retains the responsive feel of a dinghy.
- Does the boat have a dedicated engine mount?
Yes, it features a removable outboard bracket on the transom, typically suited for a 2hp to 4hp engine.
- Is the cabin large enough for overnighting?
It is 'camping style' comfort. There is a double V-berth, but no standing headroom or fixed galley facilities.
- What is the main advantage of the carbon mast?
The carbon mast is significantly lighter than aluminum, which reduces heeling and makes the boat much easier to rig and de-mast by hand.
Design History
First 18 emerged when Scandinavian and North Sea yards were scaling reliable GRP cruising platforms for owner crews rather than charter fleets. French production shaped the hull lines and interior volume for predictable manners in Baltic chop and North Sea swell. Production ran from 2015 to present; registry and owner-club sources cite approximately ~160–790 completed hulls.
Beneteau positioned the First 18 for coastal and offshore use in the 2015–ongoing production window — explaining mixed maintenance histories on the secondary market today.
Mid-production changes were mostly interior trim, engine options, and deck hardware rather than fundamental hull revisions. That means survey condition, winter storage history, and rigging invoices usually matter more than the model year printed on the brochure. When you evaluate a First 18 on Blocket, treat the maintenance story as part of the specification — not a footnote after the asking price.
Annual Ownership Costs
| Cost item | Low (SEK) | High (SEK) | Notes |
|---|---|---|---|
| Marina berth | 18,000 | 38,000 | 5.5 m class, Stockholm/Gothenburg |
| Insurance | 8 000 | 22 000 | Agreed value and cruising area |
| Haul-out + winter | 12 000 | 28 000 | Yard package varies by region |
| Antifouling + hull care | 6 000 | 16 000 | Materials and labour |
| Engine / drivetrain | 5 000 | 16 000 | Service intervals and saildrive |
| Rigging reserve | 7 000 | 20 000 | Standing rigging age |
| Deck / structural reserve | 6 000 | 22 000 | Bedding, moisture follow-up |
| Total annual | 62 000 | 172 000 | Excludes major refit years |
Annual ownership for First 18 is predictable when service records are complete. Berth, storage, and insurance dominate fixed costs in Sweden. The largest variables are rigging replacement timing and any survey-led deck or drivetrain work triggered after purchase. Keep a separate technical reserve so routine season costs stay stable — especially on Blocket boats marketed as "ready to sail" without invoices.
Pre-Purchase Survey Checklist
Pre-Purchase Inspection Checklist: First 18
Hull, Keel and Underwater Body
- Moisture-map the underwater hull; document osmosis or barrier-coat history on First 18 GRP of this era.
- Inspect keel-to-hull joint, keel bolts (if external iron), and backing structure for movement or recurring fairing cracks.
- Check rudder bearings and steering linkage under load during sea trial.
Deck and Hardware
- Test bedding at stanchions, tracks, and winches; open nearby interior access if damp stains appear.
- Inspect hatches and portlights for seal compression and core moisture at corners.
- Verify chainplate areas internally for rust staining or soft laminate.
Rig and Sail Systems
- Confirm standing rigging age with invoices; treat unknown age as near-term replacement on club-used hulls.
- Inspect mast step, spreaders, and terminals for corrosion or fatigue marks.
- Operate furling and reefing systems under realistic load.
Machinery and Systems
- Review engine and saildrive service including cooling, exhaust elbow, and mounts.
- Audit batteries, charging, and owner-added electrical work for safe fusing.
- Check tanks, bilges, and hoses for age-related seepage.
