Origin and ownership
Sealine was founded in 1972 in Kidderminster, England. The brand changed ownership multiple times across the 1990s and 2000s. Hanse Group acquired Sealine in 2013 and moved production to the Hanse facility in Greifswald, Germany.
The pre-2013 UK production and the post-2013 German production are distinct cohorts on the secondary market.
Design philosophy
Sealine hulls use moderate-V planing form (typically 17 to 19 degrees at the transom). Volvo IPS pod-drive is the standard rigging.
Production architecture and parts pipeline shared with Hanse since 2013 acquisition.
Used-market notes and known issues
Pre-2013 UK-built hulls have separate parts pipeline from post-2013 German-built. Verify build location at survey.
Volvo IPS sail-drive seal pattern on 2017 to 2020 hulls warrants inspection.
Hull-side cosmetic gel coat on Mediterranean-stored hulls shows oxidation.
Hanse Group dealer network is concentrated in Europe; US coverage is thin.
Resale
Sealine holds resale at the upper-mid luxury motor-yacht tier. Three-year depreciation runs 16 to 22 percent. Five-year depreciation runs 28 to 35 percent.
Where Sealine fits
Buyers cross-shop Sealine against Prestige, Azimut, and the smaller Princess and Sunseeker hulls. The argument is German production discipline and Volvo IPS rigging.
