Trinity3 Project

Introducing our next big adventure - Trinity3 - the next 25 years.

Trinity3 Proposals

The development of Trinity will enable our capacity to rise by 50%, an additional 1,000 visitors will enjoy a stay on board each year.

This major capital project will require an investment of £1.5 million.

Our plans include:

  •    an additional large meeting area that can be flexible to meet the needs of a diverse range of guests.  
  •    12 more guest beds in six en-suite cabins, taking our capacity from 36 to 48 beds, including one cabin for a disabled person.
  •    a new de-humidified kit storage area enabling better care of our equipment and an improved living space.
  •    a reduction in heating energy costs by using a sustainable energy technology.


The works will be done in four phases during the winter months, this will ensure that there is no impact on the groups that come and stay onboard Trinity. The work was originally planned in five phases, the last two being relatively small, but based on recent progress the decision was made to put the final two phases into one so that the project can be completed a year earlier. 

Phase 1.    Winter 2016/17 – COMPLETED - Clear engine room and foredeck. Build 'whaleback' foredeck kit store. Cost £200,000 (fully funded) 

Phase 2.    Winter 2017/18 – Build & complete upper deck saloon (ready for March 2019) & extend lookout meeting room (completed). Cost £472,201 (fully funded)

Phase 3.    Winter 2018/19 – New helical staircase linking all three floors, mechanical services & ground source heating installation, fit out of new toilets & showers, new engine room floor. Estimate £510,844

Phase 4.    Winter 2019/20 – Fit out new main deck cabins and reception, re-fit galley kitchen, food preparation & food service area. Estimate £250,000

The Project plan

New Spaces

We will do the work in four stages each winter. This enables us to maintain our usual programme of activities and to avoid letting down guests and users. It also allows us to manage the project in stages and to have some fundraising and preparation time between each phase.

Our plan is to convert the engine room into six en-suite cabins. We will reconfigure the light tower to form a central atrium, providing continuous stairway access from the entrance down to the lower deck, and up to the top of the tower.

On the main deck, we propose to create a large reception area and space around the central staircase and increase the galley area. The toilets and showers will be relocated to the lower deck.

The forward portion of the foredeck has been covered with a 'whaleback' roof for the storage of kit, including waterproofs (which are often damp and were previously stored inside Trinity). This space is heated and dehumidified. The large anchor windlass on the foredeck has been removed to create an outside training space, especially welcome for larger groups kitting up before activities.

It's on the upper (boat) deck we have planned the most obvious additions to Trinity, but in such a way as they harmonise with the traditional lines and style of the ship. The 'lookout' has been extended to meet the light tower and then continued further aft as far as the heli deck. This had created a large versatile room providing excellent views over the saltmarsh and wider estuary, and will be furnished with doors opening onto the heli deck.

The proposed design has been reviewed and refined in detail by the architect who designed the conversion from lightship in 1990. Trinity House, the original owner of the ship, has advised us on the stability and structural aspects of the design. 

Upgrading Services, Green Heating

The project not only provides a chance to develop and improve Trinity but also to refurbish some of the services that have been in service for the last 25 years. Plumbing, heating and all services on board can be upgraded and renewed as required, ensuring that they are ready for the next 25 years.

Energy costs are rising and this has a significant impact on our costs. The development gives us the opportunity to implement new green technologies, including ground-source heating, better ventilation and better insulation. All good for the environment, our guests and our budget.


We are very grateful to a number of Grant Making Trusts and individuals who have supported and continue to support the project. The project is being part funded by the European Agricultural Fund for Rural Development: LEADER grant.
