A sea trial in Panama should show the boat in the conditions it will actually face. On the Pacific, that means a tide-timed departure and the afternoon chop. On the Caribbean, it means open water outside the reef in the trade-wind swell. Test every system in the heat, not only the engines, and write the results down.
Before the boat leaves the dock
Settle the practical points in writing first:
- Who drives. Normally the seller or the seller's captain, with an AMP licence for the boat. You or your captain take the helm only with the seller's agreement and insurance cover.
- Insurance. Confirm the seller's policy covers the trial with you aboard.
- Paperwork. Check registration, the patente and safety gear aboard. For anything beyond the local area, ask the marina whether a zarpe is needed; see domestic and international zarpes.
- Who pays for fuel, and how long the trial will last.
- A cold start. Arrive before the engines have been run.
Bring the sea trial checklist so the trial follows a list, not the seller's route. Run the trial with the surveyor aboard if you can, either right after the haul-out or right before it; see boat surveys in Panama.
On the Pacific: tide, chop and traffic
Pacific tides run 4–6 m, according to the ACP's Amador tables. Plan departure and return so there is water at the marina, the fuel dock and any ramp. Currents around the Amador islands run hard at mid-tide, which is a useful test of handling at low speed.
In the dry season, roughly December to April, the bay builds a short, steep chop most afternoons. In the rainy season, mornings are often calm, and squalls and lightning build after lunch. So book a late-morning or early-afternoon slot, and turn back if a cell builds.
West of the city, at Vista Mar or in the Gulf of Chiriquí, you are closer to open Pacific swell. There, take the boat outside long enough to feel a beam sea. The Bahía de Panamá version is described in detail in surveys and sea trials in Panama City, including shipping traffic near the canal approach.
On the Caribbean: swell, reefs and short hops
The Caribbean tide is under 0.6 m, so timing is about wind, not water depth. In the dry season the trade winds raise a real swell along the Colón coast. A trial from Shelter Bay, Linton Bay or Portobelo should go far enough outside to take that swell on the bow, the beam and the quarter. Watch for:
- pounding in a head sea,
- rolling and autopilot behaviour in a beam sea,
- water coming in at hatches and ports.
Inshore, reefs and patchy charts mean the person driving should know the local water. In Bocas del Toro the lagoon is sheltered, so ask to run outside through a channel if the boat will cruise the coast. Sailboats and catamarans need wind for a fair trial: hoist every sail, tack, gybe and reef under load. Coast conditions are in cruising Panama's Caribbean coast.
What to test in tropical heat
In 28–30 °C water and strong sun, marginal systems fail on a trial or not at all, so load them all:
- Engines. Run a full-throttle sustained test. Record RPM against the rated maximum, speed, oil pressure and coolant temperature after ten minutes or more. Note smoke at start-up and under load.
- Air-conditioning and generator under full load at midday. Check the generator's exhaust water flow and its temperatures.
- Refrigeration, plus the watermaker if fitted, which is common on cruising boats bound for San Blas.
- Batteries and charging. On solar-equipped catamarans, check what the bank holds with the engines off.
- Steering, trim and stabilisers in hard turns, and backing down.
- Bilge pumps and float switches. Check how dry the bilge stays at speed in a seaway.
- Electronics. Test the chartplotter with Panama charts, a VHF radio check, the autopilot in a seaway and the windlass on a real anchoring.
Ask for oil samples to be drawn hot at the end, if the surveyor or mechanic is analysing them.
After the trial: accept, renegotiate or walk
Write down your numbers and observations the same day, and compare them with the survey. Your purchase agreement should give you a deadline to accept the boat, reject it, or propose a reduced price after the survey and trial. Deposits should come back if you reject within that window; see deposits and escrow.
Price any faults with a local mechanic or yard, not a guess. If the seller refuses a trial in realistic conditions, or keeps finding reasons to stay at the dock, treat that as information. The next steps are the lien check and closing, set out in how to buy a boat in Panama.
Your practical starting checklist
- Agree in writing who drives, who insures the trial and who pays for fuel.
- Arrive before the engines are warm and watch a cold start.
- On the Pacific, time departure and return to the tide; on the Caribbean, go outside the reef into the swell.
- Run a sustained full-throttle test and record RPM, speed and temperatures.
- Load every system: air-conditioning, generator, refrigeration, pumps, autopilot and windlass.
- Record results the same day and respond within your contract's acceptance deadline.
Frequently asked questions
How long should a sea trial take in Panama?
Long enough to reach the water the boat will use and run each test, which often means a few hours. A ten-minute run inside the marina tells you very little.
Can I drive the boat on a sea trial?
Only if the seller agrees and their insurance covers it. Whoever is at the helm should hold a suitable AMP licence; see recreational operator licences.
Should the sea trial be before or after the survey haul-out?
Either works, as long as the surveyor can attend both. Many buyers trial first, then haul out, so the surveyor can check anything the trial raised.
¿Qué es una prueba de mar al comprar una lancha?
Es salir a navegar con la embarcación antes de pagar, en las condiciones reales de uso. Se prueban los motores a plena carga, las temperaturas, el aire acondicionado, las bombas de achique y la electrónica, idealmente con el perito a bordo.
