What Should You Pay for a Lagoon 42? A Data-Driven Price Guide (2026)

The Lagoon 42 is one of the most popular production catamarans on the market. Launched in 2016, it replaced the Lagoon 421 and quickly became a favourite with cruising couples and charter operators alike. If you are shopping for one, the question is always the same: what should I actually pay?

We track every Lagoon 42 listed across 150+ broker sites in the UK and Europe. Here is what the current market looks like.

The Numbers Right Now

As of May 2026, we are tracking 63 Lagoon 42 catamarans currently listed for sale. The asking prices range from £86,000 to £565,000, with a median asking price of around £245,000.

That is a wide spread, and most of it is explained by year, condition, and whether the boat has been in charter service.

Price by Year

The Lagoon 42 has been in production since 2016, and there is a clear price curve across model years:

• 2016-2017 models: These are the earliest Lagoon 42s, now 9-10 years old. Expect to pay £150,000 to £250,000 depending on condition and equipment. Charter boats sit at the lower end, privately owned boats at the higher end.
• 2018-2019 models: The sweet spot for value. Typically £200,000 to £300,000. Old enough to have depreciated from new pricing but young enough to have plenty of life left.
• 2020-2021 models: £280,000 to £380,000. These often come with more modern electronics packages and may have seen less use due to the pandemic years.
• 2022-2024 models: £350,000 to £500,000+. Near-new boats, sometimes ex-factory or low-hours demonstrators. The premium reflects minimal depreciation.

What Affects the Price

Not all Lagoon 42s are equal. The spec differences between a base charter boat and a fully loaded private owner's boat can be £50,000 to £100,000 in value. The biggest factors:

Charter history. A boat that has been in charter for 3-5 years will have significantly higher engine hours, more wear on soft furnishings, and potentially deferred maintenance. Charter boats typically sell for 15-25% less than equivalent privately owned boats.

Engine hours. The Lagoon 42 comes with twin Yanmar diesels. Median engine hours across our listings are around 1,000-1,500 for a 2018 model. Boats with under 500 hours command a premium. Boats with over 2,000 hours should be priced lower and you should budget for a thorough engine service.

Generator. About a quarter of Lagoon 42s have a generator fitted. This is a meaningful addition worth £5,000-£8,000 in resale value.

Solar panels and lithium batteries. Increasingly common on newer models and retrofitted on older ones. A good solar and lithium setup adds genuine value for cruising buyers.

Air conditioning. Standard on some specs, optional on others. More important for Mediterranean use than for UK waters, but it adds value regardless.

Watermaker. A significant value-add for bluewater buyers. Expect it on boats equipped for offshore cruising.

How Long Do They Take to Sell?

Lagoon 42s are popular and tend to move relatively quickly compared to the broader catamaran market. The average time on market across our tracked listings is around 30-45 days for competitively priced boats. Boats that are overpriced relative to comparable listings can sit for 90+ days before the seller adjusts.

If you see a Lagoon 42 that has been listed for over 60 days with no price reduction, that is negotiation leverage.

What to Watch For

Every boat model has its quirks. Based on owner forums and surveyor commentary, here are the common things to investigate on a Lagoon 42:

• Sail drive seals. The Yanmar SD60 sail drives should be inspected carefully, particularly on boats that have sat unused for extended periods. Seal replacement is a standard maintenance item but neglected boats can develop water ingress.
• Helm station electronics. Early 2016-2017 models may have older Raymarine or B&G setups that are due for an upgrade. Factor £3,000-£8,000 for a modern chartplotter and instrument package.
• Gelcoat condition on the bridgedeck. Catamarans take slamming loads on the bridgedeck in rough conditions. Check for stress cracking or crazing.
• Rig and standing rigging. On a 2016-2017 boat, the standing rigging is approaching the 10-year replacement window. Budget £3,000-£5,000 if it has not been done.
• Tender davit condition. The factory davits can show wear and corrosion, particularly on boats kept in Mediterranean marinas.

What Should You Offer?

Based on the current market, here are rough offer guidelines by year:

• 2016-2017: £140,000 to £220,000 depending on hours and charter history
• 2018-2019: £190,000 to £280,000
• 2020-2021: £260,000 to £350,000
• 2022-2024: £330,000 to £480,000

These are starting points, not fixed rules. The right offer depends on the specific boat's condition, equipment, and how motivated the seller is. A boat that has been listed for 90 days with two price reductions is a different negotiation to one that appeared yesterday.
