Here are commercially-viable alternatives to Portugal’s NPC trimaran concept, sorted by how fast they can realistically be procured or put into service (short → longer), with pros/cons and sources so you can follow up.
Quick summary / top picks
Damen Stan Patrol / Damen OPV family — fastest commercial off-the-shelf option (lots of standardized hulls, global yards, proven export record). Good if you want short lead times, easy local build/transfer and low risk.
Austal (patrol / trimaran-derived designs) — offers trimaran experience (Independence LCS) and OPV/patrol monohulls/catamarans; good for higher speed and good seakeeping if you want a trimaran-like hullform. Lead times moderate; contractor has active production lines.
Austal Offshore Patrol 83 / similar proven OPV platforms — a concrete Austal OPV family option combining speed, endurance and easy exportability.
Navantia / Fincantieri / Lürssen (custom OPVs & PVs) — proven builders of bespoke OPVs and patrol vessels. Higher capability and customization but longer build slots and higher cost. Lürssen/large European yards are strong if you need more military features.
Existing Portuguese designs / in-service hulls (Viana do Castelo class or local build variants) — fastest to repeat or extend (uses local experience and supply chain), but not a trimaran. Good for industrial participation and short delivery if local yard capacity exists.
Why these (short explanations)
Damen Stan / OPV family — Damen’s standardized patrol and OPV lines (10–70 m range) are built in multiple yards, frequently sold “off the shelf” or via licensed construction/CO-production which shortens delivery. For quick availability you want standardized hulls like the Stan 4207 / Stan 5009 families or Damen’s OPV ranges.
Austal (trimaran experience) — if the primary reason Portugal likes the NPC trimaran is seakeeping, payload area and fuel efficiency, Austal is unique among large builders with operational trimaran experience (Independence LCS) and has OPV variants derived from proven aluminium platforms. That makes Austal a logical alternative if you want trimaran benefits with lower technical novelty risk.
Large German/Italian yards (Lürssen, Fincantieri, Navantia) — these yards build custom OPVs and patrol vessels with more advanced weapons/sensor fit and deep naval experience. Expect longer lead times but higher capability and stronger options for integration of naval combat systems.
Repeat a Portuguese/known design — extending a proven local class (e.g., Viana do Castelo) or licensing a slightly modified existing design is often the quickest route to additional hulls with Portuguese industrial participation.
Short practical decision guide (pick your priority)
Priority = fastest delivery / lowest technical risk → Damen Stan Patrol / Damen OPV (standardized, many yards, stock hulls possible).
Priority = keep trimaran benefits (speed, deck area) but reduce novelty risk → Austal (trimaran experience, OPV/patrol designs).
Austal: Corporate
Priority = highest capability / bespoke navy fit (sensors, weapons) → Lürssen / Navantia / Fincantieri (longer lead times).
Priority = fastest national / industrial solution → repeat/upgrade Viana do Castelo type or local licensed build.
Availability notes & examples
Damen: standardized production and global shipyards mean lead times can be shorter than bespoke designs; brokers/shipbrokers sometimes list Stan Patrol hulls already under construction that can be diverted or finished quickly.
Austal: actively delivering patrol boats and has OPV concepts (Offshore Patrol 83) that are offered to export customers — realistic medium-term option.
Portuguese NPC program timing: public reporting places the NPC concept and first commissioning timelines in the 2025–2026 window for early demonstrators/plans; that’s why procuring an existing off-the-shelf design may be far faster than developing a one-off novel trimaran.
Next practical steps I recommend (quick)
decide three priority axes (speed to service; cost; industrial participation / local build).
if speed is top, request Damen Stan Patrol options (sizes 30–90 m) and ask for available hulls under construction or immediate slots. (Damen often supports licensed local construction.)

if you want trimaran performance but less novelty risk, get Austal to price their OPV/patrol variants (and ask about delivery slots).
Austal: Corporate
for a higher-capability navy option, obtain indicative offers from Lürssen/Navantia/Fincantieri — but expect longer lead times.
