Where the brand began.
- Country of origin
- United Kingdom
- Time in the industry
- About 58 years since the predecessor began in 1968
Spinlock’s history begins with Offshore Instruments in 1968; the Spinlock name followed in the 1980s. Its Protect category was introduced in 2004. These dates describe the business and category, not the age of a Deckvest or a claim of an unchanged design.
Calendar-year comparisons as of 2026. Origin means the brand’s beginnings, not the manufacturing country of every product. The history sources below document the distinction.
Look beyond the badge.
Spinlock’s Control and Protect products call for different evidence. For a clutch, compare the specified rope range, loading and release instructions. For a lifejacket, inspect fit, model-specific components, servicing and the intended activity. A positive result in one product category does not establish quality across the other.
The Deckvest care resources identify inspection and replacement questions, while the support library provides product instructions. Ask the supplier to demonstrate the exact equipment and identify its current service route. Use the linked hands-on review as one product-specific perspective, alongside fit and condition checks for your own equipment.

The story behind Spinlock
Spinlock’s story begins with Offshore Instruments in London in 1968, a move to Cowes in 1976 and a change to the Spinlock name in the 1980s. Its history describes expansion from rope control into personal protection in 2004 and the Sense category in 2016. These milestones explain why the brand spans both deck hardware and wearable equipment.

Explore both sides of the sailing day.
Spinlock spans two distinct areas of sailing equipment: personal protection and rope control. Its range lets a crew explore lifejackets and harnesses alongside the clutches and jammers used to manage loaded lines on deck.
Personal equipment deserves a closer look
The Deckvest collection includes lifejacket-harness products such as the Deckvest 6D. Model options, fit and associated equipment should be explored through the official information and an appropriate supplier. Use the exact product name when discussing an existing unit or comparing versions.
Rope holding is its own category
Spinlock’s control range covers cleats, clutches and jammers, including the XXA and XXB Powerclutch family. These products address a different task from personal protection: managing a line under load. Rope specification and the intended deck application belong at the centre of a hardware enquiry.
Find the right support route
Spinlock’s support pages bring together product information and a way to ask the company a question. Its dealer directory is another route to local advice and supply. Include a product reference for support enquiries and ask the supplier which regional version and service arrangements apply.
