Worth knowing
Oy Tekno Marine Ab; cover, cost and conditions
Oy Tekno Marine Ab is a Finnish company, and the double legal form Oy and Ab already points to bilingual Finland. Under the Seiskari name it built motorboats which, according to the source, take their cue from Finnish patrol vessels. One example is the Seiskari S-300, a 9.90 metre diesel boat rated CE category C for inland and coastal waters. At the Helsinki boat show Tekno-Marine now appears mainly with marine engines, from diesels to electric drives, alongside Finn Flyer motorboats. Seiskari boats are recognisable by their plain, workboat-like lines.
Our model records list four designs, two motorboats and two motor yachts. All four share the same build years, 1997 to 2005. The two smallest, the Seiskari FR-232 and the Seiskari R-23, measure 6.9 metres each. The Seiskari S-28 Saloon comes to 8.2 metres, and the Seiskari S-40 President is the largest at twelve metres. None of the lines reaches the recent build years, so the youngest boats are some twenty years old. The names follow two patterns: FR and R for the 6.9 metre boats, S with a suffix such as Saloon or President for the motor yachts.
Every Seiskari on the market today is a used boat, and twenty years in northern waters leave their mark. Check the hull below the waterline for osmosis and the transom for moisture around engine mounts. Diesel engines of this age are often robust but want a look at service history, exhaust elbows and cooling. Ice and cold winters are hard on deck fittings, windows and seals, so look for leaks in the saloon of the S-28 and S-40. Rocky skerry waters mean the keel and propeller deserve a close look too.
