Finnish Terhi boats are made of strong and smooth, impact- and weather-resistant ABS plastic. The void in-between the vacuum-formed outer and inner hulls is filled with water-repellent polyurethane foam, which acts as structural strengthener and floatation aid. This unique so called sandwich construction also dampens hull-borne noise and makes the boat unsinkable, and thus makes the Terhi boats extremely safe to acquire and use.

When well kept and properly maintained, the Terhi boats are long-lived companions that can be passed down from one generation to the next. Ease of maintenance is one of the boats’ biggest assets, and the finishing is in a class of its own. The model range includes dinghies, rowing boats and motor boats – with either traditional combustion outboard engines or electric outboards.
