Oliver and Sam Moore reflect on the growth of Moore Brothers Company

Moore Brothers’ most recent endeavour, the hull and wing of a full-scale prototype for Rhode Island based seaglider developer Regent Craft, was delivered last winter and will go on to see the company’s first crewed flight testing in 2025. Our largest project to date both in scale (a 55ft hull and 60ft wingspan) and complexity, the past three years have demanded a transformative level of growth… from the ground up.

Since our earliest conversations in 2021 surrounding their quarter-scale, to building the hull and wing of their first full-scale vessel, supplying Regent with production engineering support and composite fabrication of their prototypes has been a fruitful, invigorating, and particularly rewarding endeavour. Regent is constantly thinking about how to build composite seagliders at scale, so it was keen to explore how to fabricate the components fast enough. We have never backed away from a challenge and we’re proud that our core team has remained invested since the day we bit off such a large project, and risen to the challenge.

We learned valuable lessons while managing a project of that size; accepting iterations of designs, engineering and executing a structure with documented quality control, empowering our team with good information and resources, and building relationships with vital partners in various aspects of the job; Symmetrix, Lyman-Morse, Janicki, Ocean State Composites and Composite Approach among them. Finally, the decision to add a 30ft x 10ft x 4ft five-axis CNC machine to our collection of equipment brought our tooling and post processing up to the highest possible standard.

Recently we congratulated Regent on the ground-breaking of their 255,000sq ft manufacturing facility in North Kingstown, RI. It’s a critical step in their path to producing seagliders and transforming transportation for coastal communities around the globe.

Today Moore Brothers has grown into a company with the capacity to execute all phases of R&D projects, requiring fabrication of premier composite structures, from engineering to tooling and through to final part fit out. Whether it is a project for the marine, industrial or aerospace world, we are ready to take on the job and we can do it all in house.
