Nautical Accessories

Boat accessories for leisure craft: over 5,000 references

Under boat accessories we group everything that is not an engine part but is still essential for a boat to work properly, safely and comfortably: mooring and anchoring, deck hardware, steering systems, plumbing, tanks, exhaust, ventilation and interior fit-out.

At Repuestos Marinos we bring together more than 5,000 accessory references for leisure boats, chosen for genuine resistance to the marine environment: AISI 316 stainless steel for exposed fasteners and hardware, UV-protected engineering plastics and materials approved for use on board.

Accessory families for boats

• Mooring and Anchoring
• Deck Hardware (13)
• Hull and Engine Room
• Steering Systems
• Marine Plumbing
• Water, Oil and Diesel Pumps
• Interior and Cabin

Each family is broken down in turn into specific categories. If you are after something particular, the shop search box accepts our reference, a description or the manufacturer's part number.

The accessories that should never be missing on board

Mooring and anchoring: mooring lines sized to your length overall, enough fenders on each side, an anchor suited to the seabed you normally use and chain or a rope-and-chain rode at least four times the depth. Add thimbles, stainless shackles and a light kedge anchor as a spare.

Safety: approved lifejackets for the whole crew, a lifebuoy with a line, extinguishers in date, flares within their expiry date, a signalling mirror and a manual bilge pump as well as the electric one.

Deck and hardware: well-backed cleats and bollards, fairleads, stanchions, guard wires, a bathing ladder and watertight inspection hatches.

Comfort: awnings and biminis, seats and pedestals, LED interior lighting, forced ventilation and everything related to fresh water and grey water plumbing.

Materials: what really lasts at sea

AISI 316 stainless steel is the standard for exposed hardware and fasteners: it contains molybdenum, which gives it resistance to chloride corrosion. AISI 304 is cheaper but pits in a salt environment, so keep it for interior use.

Avoid galvanic couples: never fit stainless fasteners directly onto aluminium without an insulator, and do not combine brass with aluminium in salt water circuits. On load-bearing hardware, check the stated breaking load and always work with a generous margin.

With plastics, look for declared UV protection. A cable gland or an inspection hatch with no anti-UV treatment turns brittle after two seasons of Mediterranean sun.

Warranty and 24-48 h shipping

Every accessory we sell is selected for marine use and comes from manufacturers with a track record in the industry. Each product page sets out the material, the dimensions and, where relevant, the working load and approvals.

Shipping in 24-48 h to mainland Spain and the Balearics, 3-5 days to the Canary Islands and the rest of the EU. Orders placed before 14:00 leave the same day. Returns within 14 calendar days, plus technical support by phone and WhatsApp for questions about fitment or parts diagrams.

Frequently asked questions about boat accessories

Which boat accessories are compulsory on board?

The compulsory safety equipment depends on your navigation area and on the country, but it generally includes approved lifejackets for the whole crew, a lifebuoy, extinguishers in date, distress signals within their expiry date, bilge pumping equipment and navigation lights. Always check the rules in force for your navigation area, because the requirements vary across zones 1 to 7.

What is the difference between AISI 304 and AISI 316 stainless steel?

AISI 316 contains molybdenum, which gives it far greater resistance to chloride corrosion, in other words to salt water. AISI 304 is cheaper but pits in a salt environment. For exposed hardware and fasteners on a boat always use AISI 316; keep 304 for interior use.

How much anchor rode and chain do I need?

As a general rule, the anchor rode should be at least four times the depth where you anchor, and more in bad weather. The anchor should be chosen for the type of seabed typical of your area, and the chain or rope-and-chain rode should be sized to the boat's length and displacement.

What is a galvanic couple and how do I avoid it?

It is the corrosion that appears when two different metals come into contact in the presence of salt water, which acts as an electrolyte. The less noble metal corrodes. To avoid it, do not fit stainless fasteners directly onto aluminium without an insulator in between, and do not combine brass with aluminium in salt water circuits.

Do plastic accessories stand up to the sun?

Only if they carry UV protection declared by the manufacturer. A cable gland or an inspection hatch with no anti-UV treatment turns brittle after two seasons of Mediterranean sun. Always check this detail on the product page.

Can I order an accessory that is not shown on the website?

Yes. We work with several distributors and can track down references that are not listed. Send us the manufacturer's part number, a photo or a description with the dimensions, and we will confirm availability and lead time.
