A rig is not just a collection of components.
It is an integrated system in which every single decision affects safety, performance and service life.

[ WHY COMPLETE MATTERS ]
BECAUSE RESPONSIBILITY CANNOT BE DIVIDED
When a rig is assembled from multiple suppliers, grey areas arise.
Different tolerances. Different assumptions. Different responsibilities.
A complete rig solution from JOHN MAST removes that uncertainty.
One partner. One technical philosophy. One clear responsibility.
All components are developed to function as a unified system — optimised for strength, balance and long service life. When responsibility is gathered in one place, the result is better. Every time.

[ WHAT WE DELIVER ]
A FULLY INTEGRATED RIG — ENGINEERED DOWN TO THE LAST DETAIL
Our complete rig solutions are developed based on the boat’s design, intended use and expected service life. Nothing is standard. Everything is specified.
A complete rig solution typically includes:
- Mast and boom designed for an optimal strength-to-weight ratio
- Standing and running rigging specified for purpose and load
- Custom-designed fittings, chainplates and hardware
- Structural calculations, load analysis and documentation
- Technical coordination with shipyard, designer and owner
- Quality control at every stage — from construction to delivery
The result is a rig that works as a unified system — not as individual parts.
[ BEFORE YOU DECIDE ]
THREE FACTORS THAT DETERMINE WHETHER A COMPLETE RIG SOLUTION IS THE RIGHT CHOICE
A complete rig solution is not for everyone.
But when it is the right decision, it is rarely open to debate.
Owners and shipyards who prioritise safety, operational reliability and long-term value over short-term savings. Typically projects where requirements are clear and compromises are unacceptable.
When the rig is a critical part of the project’s overall quality — technically, economically and operationally. The higher the requirements, the greater the value of having one integrated technical partner.
With a technical dialogue — not a quotation.
The project’s framework, ambitions and intended use are clarified before the solution is defined.
