Fishing being the livelihood of many readers here, rough waters is a part of your life. You must be well versed in trimming tactics if you are a novice in this matter. It is your duty to respect the harsh weather & rough seas.

Trimming is an important part of boating. For all the newbies out here, trimming is the process through which the boat driver tilts the boat to a specific angle, having its bow elevated while the latter part (often called the trim) submerged in the water.

Trimming a boat adds up to your boat economy, increases the speed & ensures even weight distribution. It works on the fundamentals of an inclined plane.

Boat trimming could be dangerous especially if you are an amateur. This article will enumerate a step-by-step process for successfully trimming your boat in rough waters. In the end, it will also include some safety tips.


Preparation is an integral step. It involves determining the trim angle, the elevation the speed at which you are going to accelerate.

For the initial two minutes, you must closely monitor the wave trends, the frequency & the wave height. You must have an approximate idea of the average depth of water. It must also be ensured that the weight on your boat is equally distributed.

The next step in preparation is to put your boat into the neural engine. Ensure that your boat has enough boats prior to the departure. Your boat must be able to move without any major jerks & bumps before we move on to the next step in this article.

Step 1

This is actually the first step where you start trimming. Before starting this, you must assure that the preparatory phase is completed.

Remember to put on your safety vests (life jackets) as safety is the first priority. If on a beach, it is highly advised that the boat is under shallow waters (below 20 feet) while this phase is being done. You must wait for the wave to descend before you do the following.

  1. There is a trim switch in every boat. It is used to tilt the boat to an angle. Thus, you need to use this switch to tilt the back of the boat underneath. I
  2. If your boat has a tilt gauge, then you will notice that at a moment, the boat is fully trimmed down. If the boat does not have it, then you will be indicated via a peculiar sound from the motor.

Step 2

This step must be done with extreme caution since there are chances of experiencing shakes and jerks. You must have the lifejackets fastened & must ensure that there is no movement in the boat. You do the following.

  1. Put the engine in the forward gear in order to cruise.
  2. Accelerate till the normal cruising speed of the boat. You must see that the route is clear without any obstacles & distractions. You should be notified about your speed by looking at the speedometer.

Step 3

This is a crucial step as there are many things involved at the same time. You have to look at the route, speed of the boat, the tilt gauge/motor noise & the boat dynamics.

For beginners, it is advised that you have a company of another pal for better multitasking.

  1. You must again approach the trim switch. This time you need to tilt the engine in the upwards direction. The cruising speed of the boat must be maintained.
  2. You will eventually notice that the entire altitude of the boat with respect to the water has changed. You can see the bow of the boat elevated, perhaps there is an increase in the speed. There are further possibilities for jerks & shakes so you should instruct everyone to be static.
  3. You must continue to tilt this engine up & now you will notice a drop in the speed on the speedometer. The propeller on the boat will begin to move more rapidly, thus ventilating.
  4. If you increase the trim of the engine abnormally high, then the bow of the boat will start to elevate higher in a rhythmic manner. You must prevent this from being prolonged as it can cause a safety hazard.

Step 4  

During step 4 you are supposed to do the following:  

  1. Reduce the tilt of the boar by lowering the trim switch. This must not be done in one go, rather you must do it in small increments.
  2. Gradually you will notice that the boat will be near its cruising speed. The ventilation by the propeller will now cease. Once your boat reaches the exact cruising speed and the rpm is constant, then you must stop operating the trim switch.
  3. Congratulations your boat is at its maximum efficiency & it is running economically. Your boat is now successfully trimmed. Further, you can adjust the trim switch with respect to the height of the wave. You must ensure that you are at the cruising speed.

Word of Caution

  1. Always keep your life vest fastened. Also, instruct other passengers to wear it.
  2. Start the entire process in shallow waters.
  3. Before departing ensure that there is enough visibility for you to drive the boat. A high level of mist or fog could lead to fatal accidents against unnoticed obstacles.
  4. If you are a newbie, it is highly recommended that you practice the entire process in fresh waters (still lake, river, backwaters).
