Technohull Seadna 999S: cover, cost and conditions

Little is recorded with us about the Technohull Seadna 999S, and the type of boat is not determined. The model sails in our portfolio, and so far we do not carry any further models of the brand. You enter the dimensions and drive in the application.

The replacement value is the starting point for the agreed value. Take your bearings from what a comparable boat with the same equipment would cost today, and list electronics and equipment separately.

The agreed value thus arranged is paid out in the event of a total loss with no deduction for depreciation, in the Premium tariff with no age limit. Up to a sum insured of 2.5 million euros the policy runs online, above that we examine the individual case.

What is a used Technohull Seadna 999S worth?

A used Technohull Seadna 999S built between 2013 and 2020 in average condition is typically worth

between €78,700 and €171,500 today.

Well kept boats with recent engines sit above that, boats with defects below.
