With over 235 000 produced boats over the years, Terhi is by far the most sold boat brand in Finland. All Terhi models are manufactured out of strong but smooth, impact- and weather-resistant ABS plastic. ABS plastic is a praiseworthy boat building material, as potential damages are possible to repair even in a DIY manner. The void between the exterior and interior hull is densely sprayed with single-cell water non-absorbent polyurethane foam, which as it dries glues the hulls tightly together simultaneously acting as structure strengthener and floatation aid. This unique hull construction we call Sandwich structure, and it makes our boats unsinkable, durable and it also reduces hull-borne noise. The Terhi boats are long-lived and extremely easily maintained boats as long as they are kept and winter stored well. This is why it is not uncommon that Terhi boats are passed down from one generation to another. Compared to our competitors, the finish of our boats is truly in a class of its own, making our boats not only easy to clean and maintain, but also easy on the eye. No wonder that Terhi is so popular in its home country – and increasinly so also abroad.
