Direct peers

• Burgess: Global superyacht sales, charter and management company operating across the same Mediterranean/Caribbean/Asia geographies. Burgess is the most direct comparable to Sea Alliance's full-service superyacht brokerage, charter and management offering.
• Allied Marine: Yacht brokerage and charter company (part of MarineMax) offering sales, charter and yacht management. Competes with Sea Alliance for brokerage mandates and charter clients, particularly in the yacht (vs. superyacht) size band.
• Denison Yachting: Yacht brokerage and charter company with a strong Mediterranean and U.S. presence. Competes in the same brokerage and bareboat/crewed charter categories, particularly for vessels in the 40–120ft range that overlap Sea Alliance's portfolio.
• Fraser Yachts: Full-service superyacht broker (sales, charter, management) with strong Mediterranean presence. Fraser's portfolio breadth, from 24m to 80m+, overlaps directly with Sea Alliance's superyacht charter management range (40–180ft).
• Northrop & Johnson: Global yacht brokerage with sales, charter and management services for yachts and superyachts. Competes head-to-head in the same European and Caribbean markets Sea Alliance serves, including pre-owned and central-agency charter listings.
• Worth Avenue Yachts: Yacht brokerage and charter firm specializing in yacht sales, charter management and new construction. Direct competitor for central-agency charter management mandates and yacht sales deals in the Mediterranean and U.S. markets.
• Edmiston: Superyacht sales, charter, new construction and management company based in Monaco. Overlaps with Sea Alliance on crewed charter placement, central-agency listings and yacht management for large vessels in the Mediterranean.
• IYC (International Yacht Company): International yacht brokerage and charter management company competing for the same central-agency superyacht clients. IYC's global charter portfolio and central-agency charter management model closely mirrors Sea Alliance's Gianetti ONEIRO I appointment.
• Camper & Nicholsons: Historic yacht brokerage, charter and management firm with a comparable Mediterranean-centric superyacht focus. Like Sea Alliance, Camper & Nicholsons offers sales, charter management and yacht management to HNW clients globally.

Broad incumbents

• YachtWorld / Boats Group: Largest global yacht listing marketplace and SaaS/CRM provider (Boats Group) that Sea Alliance already syndicates listings through. Functions as a broader incumbent enabling layer rather than a direct services competitor, but increasingly shapes buyer/seller discovery dynamics in the brokerage industry.
