Trinity3 Project - one more phase to go!

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 are being done in four phases during the winter months, this ensures 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 £191,909 (fully funded) 

Phase 2.    Winter 2017/18 – COMPLETED - Build & complete upper deck saloon & extend lookout meeting room. Cost £433,999 (fully funded)

Phase 3.    Winter 2018/19 – COMPLETED - New helical staircase linking all three floors, mechanical services & ground source heating installation, fit out of new toilets & showers, new engine room floor. Cost £513,868 (fully funded)

Final Phase    Winter 2019/20 – Create disabled cabins with en-suite facilities on main deck and four new ensuite cabins on lower deck to increase accomodation. Refit Saloon, Galley & food preparation areas. Estimate £397,000

The Final Phase

We are excited that the final phase is now in sight and is due to start in late October 2019. It will be completed in early 2020 before the start of the new season. If you are interested in financially supporting the final phase we would love to hear from you. 


The Project plan

New Spaces

The work is being done 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 four en-suite cabins. We have reconfigured 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 have created a large reception area and space around the central staircase. It also allows the addition of a disabled cabin. The toilets and showers have been relocated to the lower deck (on the same level as the accomodation.

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 has created a large versatile room providing excellent views over the saltmarsh and wider estuary, and has been furnished with bi-fold doors opening onto the heli deck.

The designs were reviewed and refined in detail by the architect who designed the conversion from lightship in 1990. Trinity House, the original owner of the ship, have commented on the stability and structural aspects of the design along with our naval architect. 

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 have been 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 gave 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. Phase 3 of the project is being part funded by the European Agricultural Fund for Rural Development: LEADER grant.

With funding from the Magnox socio-economic scheme we were able to purchase and install some great new AV equipment in the Upper Saloon.
