To improve the exit to plane with two passengers, it is recommended to shift the weight of passengers closer to the nose of the boat or use an elongated engine lower unit, if the transom design allows.
In quiet water, the boat runs smoothly and predictably, but like any flat-bottom, it can be rolled in a strong lateral wave, which is a physical feature of this type of hull. However, the buoyancy margin and hull width make it feel confident even in the face of an unexpected gust of wind.
The optimal power of the engine for confident planing with two passengers is 6-8 hp, although the passport allows installation of up to 15 hp.

Frequently Asked Questions (FAQ)
Can I install a 15 hp engine on the Terhi 400?
Technically, the transom can withstand the installation of the engine up to 15 hp, but the rated carrying capacity of the boat (300 kg) limits the possibility of using such power with passengers. With a 15 hp engine, only one person can be on board, otherwise you will exceed the permissible weight, which is unsafe.
Do I need to paint Terhi's aluminum boat?
No, you don't need to paint the case, you don't even recommend it without special training. Aluminum-magnesium alloy forms a protective oxide film itself. Paint on smooth aluminum is poorly maintained and peels off quickly, and the process of painting quality requires complex priming.
How does the boat behave in the side wind?
Due to the high side and light weight, the sailing of the boat is noticeable. In strong side winds, it can be demolished, so it is important to have a reliable anchor and be able to maneuver the engine correctly. Experienced owners recommend always having an anchor weighing at least 3-4 kg with you.
Will the Terhi 400 fit on the roof of the sedan?
The length of the boat is almost 4 meters, which is the limit value for many passenger cars. For safe transportation on the roof of a sedan or hatchback, you will necessarily need a retractable flag marker on the stern of the boat to indicate the size for other road users, as well as reliable soft crossbars.
