As a captain, sea trials were standard no matter if a boat was being acquired, sold, or coming out of a long out-of-service period. I didn’t particularly enjoy every trial, but it was necessary. If you’re in the market for a new boat or have had extensive maintenance work done, it is important to know how to test a vessel properly. Here is what you need to know about a boat sea trial. 

Where Is A Sea Trial Performed

For the most part, the boat must be tested in open waters where the throttles can be pinned without concern. However, understand that the conditions must be right. Rough seas are not conducive for testing a vessel. 

In my career on boats, I most often ran trails on the ocean. Comparatively, a lake or open area of a river is equally as effective. 

Invite A Mechanic Aboard The Sea Trial

One of the best pieces of advice is to hire a mechanic to come aboard when testing a used vessel. Yes, it will cost money, but it is better than making a poor decision, which could result in thousands of dollars in repairs. 

I have had mechanics onboard during trials after lengthy maintenance work and while in the process of selling boats. 

The mechanic typically inspects the motor or motors while performing diagnostic testing. Advanced electronic testing today yields a significant amount of information about the performance of the motors. 

What Should Be Tested During A Sea Trial

In order to execute a trial, it is imperative to create a punch list. The punch list will prevent forgetting to inspect critical components of the vessel further. Remember, you don’t want to miss a red flag if you’re buying a boat. Here is what should be tested during a sea trial. 

Before The Trial

Keep in mind that you’ll want to do a complete walkthrough of the vessel before departing the dock. Take a close look at the following items.

  • Damage to the surfaces of the boat or beneath the waterline if the boat is hauled.
  • The condition of the cushions. 
  • The functionality of moving parts, wiring, and the condition of the batteries.

What To Test While On The Water

In some cases, you’ll have additional people onboard the vessel for trials. They include mechanics, surveyors, and others. Here is what to test while you’re on the water. 

  • Ensure that the steering system is functioning properly. Turn the wheel from side to side.
  • Check the speed of the vessel. Determine how well it accelerates, the movement of the throttle, and maneuverability at all speed ranges. 
  • Listen for sounds that are not standard while starting the vessel, during operation, and while shifting in and out of gear. 
  • Pay attention to the comfort of the boat and determine if it is suitable for your use both for lounging and the type of ride it provides. 

Undoubtedly, a sea trial can be overwhelming, especially for a first-time boat buyer. As mentioned before, this is why you should create a list to keep on track during the window you have the opportunity to trail a boat. 

Lastly, make sure to take notes. Taking notes will allow you to weigh the pros and cons to make a more informed decision. 

Evaluating The Data From A Sea Trial

Without a doubt, you will have a significant amount of data to analyze after the trial is complete. Remember, you don’t want to overpay or purchase a boat that is not an ideal fit for our needs. Plenty of boats are on the market, so you continue to shop and find the perfect fit. 

One of the biggest deciding factors is the mechanical condition of a used vessel. Engine work is likely the most expensive component of boat ownership. You’ll have to really like the ride and appearance of the vessel if it is found to be unsound mechanically. 

The point is that you don’t want to settle. This is the reason why running a sea trial is imperative if you’re considering buying a used vessel

Making An Offer 

In the case that you feel the boat is right for you, you’ll again want to consider the data. Avoid overpaying for a boat. Take the facts and offer what is fair while factoring expenses in needed repairs. 

Of course, you don’t want to insult the seller by lowballing them. Consider fair market value when coming up with the offer. 

Sea Trialing A Boat Is A Necessity

In order to get an accurate assessment of a vessel, it is imperative to run a sea trial. The testing gives you all of the data you need to make an informed decision about buying a vessel. Remember to create a checklist so that you can stay on track.
