Fifty-six firms in Guernsey's marine trade, weighted toward St Peter Port (22) with secondary clusters in St Sampson and Vale (8 each). Repair leads the specialisation mix (13), followed by charter and storage (7 each), sales and marine engineering (5–6). The oldest, Bachmann Group and Marine & General, both date to 1974; the newest opened 2024. —
Thirteen firms — full-service boatyards, marine-engine specialists, and metal fabricators — anchored by authorised engine dealerships.
Ten charter operators — the oldest trading since 1992, the newest launched 2024; four working out of St Peter Port harbour.
Nine dealers and brokers — five clustered at St Sampsons Marina, with the oldest, Aquastar, building yachts there since 1969.
Seven entities — two States-owned harbour authorities, a 1923 boatowners' association, and Beaucette's quarry-cut marina.
Five firms — one manufactures sonar for offshore and defence in Vale; the others install and wire pleasure craft.
Five firms offer marine surveys — one YDSA Fellow dedicated to it, the rest folding surveys into engineering, electronics or fiduciary work.
Five firms — one dedicated rigger (Guernsey Yacht Rigging, 2024), one sailmaker (W. Hall), three boatyards adding rigging alongside.
Four yards — Aquastar (1969) for custom 38–85ft motor yachts, Marine Fabrications (1985) for welding, RH GRP for fibreglass.
