Sealine S 28: cover, cost and conditions
How much does the name Sealine S 28 (twenty-eight) matter to the premium? Hardly at all. What counts is the type of boat, the year, the value, the engine output and the cruising area, the five fields of the online calculator.
What should you budget for the Sealine S 28 (twenty-eight)? It starts from €49 a year. For a Sealine S 28 at the usual market value of €52,000 the premium is €1,037 a year: liability and hull in Basis-Plus, North Sea, Baltic and Mediterranean, 225 hp (assumed), hull excess €500, paid annually. Hull cover accounts for €888, liability for €149. Tariff as of 13.11.2026, your own boat may differ. Hull cover follows the value of the boat. Partial: fire, storm, lightning, theft of the whole boat, winter storage. Full, on top: collision, grounding, vandalism, theft of parts. A total loss means the agreed value, in the Premium tariff without new-for-old deductions.
The Sealine S 28 (twenty-eight) may be second hand, imported or ordered new, and the berth may be at home or abroad: we write it in each of these cases. The international certificate of insurance comes by itself in ten languages, and cover taken out before the handover already includes transport and the first launch.
Not to be mixed up with its sisters: this is the Sealine S 28, number twenty-eight.
