Sealine S390: cover, cost and conditions
How much does the name Sealine S390 (three hundred ninety) 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 S390 (three hundred ninety)? It starts from €49 a year. 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 S390 (three hundred ninety) 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.
