Yacht Gym Equipment: Manufacturers Compared

By OutdoorGym.com Editorial Team · Published October 4, 2026

We found ten makers of gym equipment that address yachts or ships on their own websites, and they are very different businesses. Pent in Poland and Paragon Studio in the UK supply bespoke gyms for vessels; Hantlar, Ive Outdoor in Poland, and the UK makers Klink and MH Luxury Collection make free weights that they state are for yacht use; Akuis, Ciclotte and Technogym in Italy offer individual products that they name for use on board; and Life Fitness in the USA runs a cruise-ship programme. This overview compares all ten on what each one publishes: company type, steel grade, product scope, vessel fixings and warranty. Every maker fact comes from the maker’s own public pages, checked in October 2026, and anything we did not find on those pages is marked “n/d”.

For the engineering background - what salt does to coated steel and how to specify a gym at sea - see our guide to yacht and superyacht gyms. This page answers the next question: who actually makes the equipment.

How we selected the makers

A maker is included only if its own website carries an explicit statement about yachts, superyachts or ships. A stainless steel dumbbell is not a yacht product just because a reseller says so. That rule leaves out makers whose own sites carried no such statement on the pages we could open, however suitable their products may be; makers of stainless steel free weights in general are compared in our stainless steel dumbbells comparison. Absence from this page is not a judgement of quality; it only means we found no yacht or ship statement to compare. Makers may also offer more on request than they publish; the table records only what is published.

The makers are listed alphabetically. This is not a ranking.

Three points that frame the comparison

The steel grade is the first filter. In grade 316, about 2% molybdenum is added to improve corrosion resistance, which is why it is commonly termed marine grade; in a marine environment, grade 304 is usually only suitable for fittings that are frequently washed with fresh water (Australian Stainless Steel Development Association). For welded structures, the low-carbon 316L types avoid an additional corrosion risk (British Stainless Steel Association).

316 is not corrosion-proof. The British Stainless Steel Association is explicit that in contact with seawater the corrosion resistance of 316 types is limited and that they cannot be considered corrosion proof in all situations. A maker’s “marine grade” is where the specification starts, not where maintenance ends. The material argument is set out in our 304 vs 316 and stainless vs galvanised comparison.

One flag-state code requires heavy equipment to be fastened. The Red Ensign Group Yacht Code (Part A, July 2024 edition) states in its accommodation chapters that all heavy items of equipment, such as ballast, batteries and cooking stoves, shall be securely fastened in place. It does not name gym equipment; reading it as covering a loaded rack or a machine is our interpretation, so the fixing method should be confirmed with the yacht’s naval architect and flag administration. That is why published vessel fixings have their own column in the table below.

Akuis (Italy)

Akuis makes one product relevant here: Sintesi, a digital cable station in which electric motors replace weight stacks. The maker describes it as reproducing 14 gym machines in a footprint of two square metres. In an Italian-language post on its own blog, it states that the station suits every type of vessel, from a cruise ship to a luxury yacht, below deck or in semi-open areas. The structure is two tubular aluminium modules fixed to a wall with quick-release brackets, and it is described as 100% made in Italy. Akuis publishes a 2-year limited warranty. It does not publish a marine corrosion specification or an ingress-protection rating on the pages we checked.

Ciclotte (Italy)

Ciclotte is a designer exercise bike with an electromagnetic resistance system, made in carbon fibre and steel, with bespoke versions in other materials. The maker names the yacht as one of the settings the bike is designed for, alongside the home, the hotel and the training facility. That is the extent of the published yacht material: there is no marine specification, deck rating or warranty on the maker’s pages we checked. With no marine specification published, we would treat it as a piece for an interior gym unless the maker confirms otherwise.

Hantlar (country not stated)

Hantlar makes dumbbells only, and its steel statement is detailed. It states that it manufactures marine-grade dumbbells from 316 stainless steel, lists 316L pro-style dumbbells, and says the handles, plates, end caps and bolts are all made from 316, from solid bar with no castings, coatings or plating. It also states that each set ships with a material test certificate for the metals used. The maker names yacht gyms, cruise gyms and beach gyms as the intended settings, publishes a starting price per pound (lb) and a lead time of six weeks, and offers laser-marked end caps. Its site does not state where the company is based or where the dumbbells are made, and we found no published warranty.

Ive Outdoor (Poland)

Ive Outdoor manufactures outdoor fitness equipment in stainless steel: adjustable-load strength machines, functional rigs, benches and dumbbells. On its product pages, the explicit yacht statement appears on the dumbbell page. The stainless steel dumbbells come in two versions: 304, intended for fitness clubs and home gyms, and 316, which the maker says is intended for outdoor or yacht gyms. The dumbbells are described as 100% stainless steel, protected by passivation, in a range from 1 to 100 kg, and can be personalised with a logo or initials.

For its machines, the maker states 100% stainless steel construction and a 10-year commercial warranty, and its rig pages cite EN 16630, the European standard for permanently installed outdoor fitness equipment. Several station and rig pages describe the material as marine-grade stainless steel without a grade number. For the strength machines we found no numbered grade, no statement about vessels and no vessel fixings on the pages we checked. Our guide to yacht and superyacht gyms reports the maker’s statement that its standard range is 304 and that it builds gyms in 316 on request; because that is not on the product pages, it is not in the table below, and a buyer who wants the machines on board should ask in writing which steel grade they are made of and how they would be fixed.

Klink Fitness, registered in Northern Ireland, makes adjustable dumbbells and an adjustable barbell, designed and manufactured in the UK with CNC machining. The maker positions the range for the luxury fitness market and the superyacht industry, and notes that the sets are easy to carry for workouts on deck. One set of its OPOLIS range makes pairs of 8, 12, 16 and 20 kg or a single dumbbell up to 32 kg, which is the argument for a vessel: many weights in a small case. The material is described as premium stainless steel without a grade, and the range can be customised with a logo. Its terms and conditions refer to a guarantee; a product warranty period is not stated on the pages we checked.

Life Fitness (USA)

Life Fitness addresses ships rather than yachts: it runs a cruise programme within its hospitality business, aimed at the exercise facility aboard a cruise ship. It is included because its statement concerns vessels, and because the questions a yacht buyer should put to a mainstream maker are the same. On its cruise page the maker states no marine material specification, vessel fixings or warranty for use at sea, does not itemise products, and makes no yacht statement.

MH Luxury Collection (United Kingdom)

MH Luxury Collection is a design brand for dumbbells and weighted bars; its site gives a UK contact and says the products are created with manufacturers in the UK. The maker states that the range is focused on bespoke solutions for the superyacht community, private residences and elite gyms, and that it uses stainless steel sourced through interior-design specialists in the superyacht industry. Its bars come in 4 to 12 kg, and engraving and custom logos are offered. No steel grade, deck rating or warranty is published on the pages we checked.

Paragon Studio, with Gym Marine (United Kingdom)

Paragon Studio designs high-end gym equipment for private, residential and superyacht gyms and, by its own description, has it made by specialist workshops in the UK and elsewhere. In 2026 it acquired Gym Marine, a designer and outfitter of superyacht gyms since 2014, which continues to operate under its own name within Paragon Studio. It is therefore both a maker of its own range and an outfitter that also supplies other brands, including co-branded cable machines.

Its own range covers dumbbells, kettlebells, benches, storage, wall bars and cable machines, plus an onboard wellness kit that fits a custom drawer insert. The dumbbells and benches we looked at combine stainless steel or bronze with hardwood. The vessel-specific detail is in the fixings: racks can be supplied with rear wall fixing brackets, and the maker refers to a sea-secure range of weight storage racks. Benches can be made to measure, and the lead time stated for its dumbbells is 12 to 14 weeks. A steel grade and a warranty are not published on the pages we checked.

Pent (Poland)

Pent, established in 2011, manufactures its collections in-house in Poland, made to order. It publishes detailed yacht-specific material: the maker says it develops bespoke fitness equipment and complete wellness solutions for new-build yachts, refits and existing vessels.

On materials, Pent states that its yacht collections can incorporate AISI 316 or 316L stainless steel, with woods such as teak, walnut and oak treated for marine environments, and upholstery chosen according to position on board. The 316 statement is conditional - it depends on the project and the exposure - so it is worth confirming per piece. On fixings, it lists dedicated floor or wall mounting systems, discreet securing mechanisms and stability reinforcements. The range covers cardio and strength: a motorised treadmill and a manual curved treadmill, a bike, an elliptical, a rower, a cable trainer, benches, dumbbells, kettlebells, barbells and a Pilates reformer. The published warranty is 24 months, or 12 months for commercial use, and lead times run from 3-5 weeks for small orders up to 20 weeks.

Technogym (Italy)

Technogym names the yacht once on the pages we checked, as a setting for its Personal line - a treadmill, bikes, a cross-trainer, a bench, a rack and the Kinesis cable station - and runs a separate wellness programme for cruise ships, including top-deck training. What it does not state on those pages is a marine material specification, vessel fixings or a warranty for use at sea.

“n/d” means we did not find that item on the maker’s pages we checked.

How to choose

  • A complete interior gym on a new build or refit. Look at the makers that publish both a yacht programme and vessel fixings: Paragon Studio and Pent. Both publish lead times of weeks to months, so the order belongs in the build schedule.
  • Free weights for an exposed deck or beach club. Start with a published 316 grade and confirm that it covers the whole piece, fasteners included. Hantlar states 316 for the whole dumbbell, bolts included; Ive Outdoor states a 316 version of its all-stainless dumbbells; Pent offers 316 or 316L per project. For wooden handles or leather grips, ask the maker how the material is treated for exposure.
  • Very little space. An adjustable dumbbell set (Klink), a kit stored in a custom drawer insert (Paragon Studio) or a two-square-metre cable station (Akuis) replaces a rack of fixed weights.
  • Mainstream machines for an interior gym or a cruise ship. Life Fitness and Technogym run programmes for ships. Ask for the corrosion terms in writing, because none are stated on the pages we checked.
  • Cardio on deck. A self-powered machine avoids a marinised power supply. Among the makers here, Pent lists a manual curved treadmill; our overview of self-powered curved treadmills explains how the design works.

Whichever maker you shortlist, three questions separate a marine specification from a marketing phrase: which steel grade applies to which parts, how the piece is fixed to the vessel, and what the warranty says about use at sea.

Frequently asked questions

Which companies make gym equipment for yachts and superyachts?

We found ten makers of gym equipment that address yachts or ships on their own websites: Akuis, Ciclotte and Technogym in Italy; Hantlar, whose site does not state a country; Ive Outdoor and Pent in Poland; Klink, MH Luxury Collection and Paragon Studio, which acquired the outfitter Gym Marine in 2026, in the United Kingdom; and Life Fitness in the USA, which runs a cruise-ship programme. They differ widely: some supply whole bespoke gyms, others a single product.

Which yacht gym equipment makers publish a marine-grade steel specification?

Three of the ten publish a numbered steel grade for marine use. Hantlar states that it makes its dumbbells, bolts included, from 316 or 316L stainless steel. Ive Outdoor publishes a 316 version of its stainless steel dumbbells, intended for outdoor or yacht gyms. Pent states that its yacht collections can incorporate AISI 316 or 316L, depending on the project. The other seven publish no numbered marine grade on the pages we checked.

Is 316 stainless steel corrosion-proof on a yacht?

No. Grade 316 contains about 2% molybdenum, which improves resistance to chlorides, and it is the grade commonly called marine grade. But the British Stainless Steel Association states that in contact with seawater its corrosion resistance is limited and it cannot be considered corrosion proof in all situations. Rinsing with fresh water and designs that let water drain still matter, whichever maker you choose.

Which makers publish fixings for use on a vessel?

Three of the ten. Akuis fixes its cable station to a wall with quick-release brackets. Paragon Studio offers rear wall fixing brackets for its racks and refers to a sea-secure range of weight storage. Pent lists floor and wall mounting systems, securing mechanisms and stability reinforcements. The Red Ensign Group Yacht Code states that heavy items of equipment shall be securely fastened; it does not name gym equipment, so the fixing method should be confirmed with the naval architect and the flag administration.

Do Technogym and Life Fitness publish a marine specification?

Not on the pages we checked. Technogym names the yacht as a setting for its Personal line and runs a wellness programme for cruise ships, and Life Fitness runs a cruise programme, but neither maker's pages state a marine steel grade, vessel fixings or a warranty for use at sea. Before placing standard commercial machines on a vessel, ask for the material specification and the corrosion terms in writing.

What warranty do yacht gym equipment makers publish?

Few state one on the pages we checked. Akuis states a 2-year limited warranty. Ive Outdoor states a 10-year commercial warranty on its machine and bench pages, but not on the dumbbell page that carries its yacht statement. Pent states 24 months, reduced to 12 for commercial use. Klink's terms refer to a guarantee without stating a product warranty period. For Life Fitness and Technogym we read only the yacht and cruise pages, which state no warranty for use at sea. In every case, ask what the warranty says about use at sea.
