Hydrotab’s New Composite 300SR Trim Tabs

Getting on plane with the 300SR trim tabs activation. The RIB was standing on plane at slower speed, keeping its bow clearly lower without even increasing fuel consumption significantly.

Lowering the trim tabs by 50%, we measured 3 seconds less time of planning with the minimum raise of the bow on starting.

Then we focused on our recordings in low cruise speeds with which we will usually travel most hours of the day. Keeping the engine trim constant at 40%, we started experimenting with the position of the vertical 300SR trim tabs.

It was obvious that when the trim tabs were completely pulled up, the bow insisted on standing very high and in no case could we have a decent cruise in the area of 15 to 25 knots.

n contrast, by lowering the trim tabs by 50-70%, the behavior of the RIB changed completely. The bow was lowering considerably, the hull began to cut the water from its bow section and our cruising became softer while at the same time we ensured a very good cruising angle.

We were surprised when we found out that while traveling at 23 knots, our speed increased by 2 knots when we lowered the trim tabs by 50%, without even increasing fuel consumption, which leads to greater autonomy.

It was obvious that we have in our hands a great tool that will enable us to travel comfortably at low speeds, improving the fuel consumption and ride quality, elements that are extremely important especially in bad weather conditions.
