Sealine S390 Video Review: Two Sunroofs and a Bow Cabana
By the YachtWay editorial deskUpdated October 2026Video walkthrough6 min read
The Sealine S390 is a 41 ft sport cruiser built by HanseYachts. We walked her at the dock in Palma. The swim platform lowers to knee depth, the cockpit turns into one large sunbed, and two sunroofs open above the cockpit and the helm. At the bow a cabana sets up over the sunbed, and below deck there is an owner's cabin, a full-beam guest cabin and a head.
A lot of cockpit for a 39 footer
We started at the stern, where an optional outdoor galley sits right above the swim platform. The cockpit backrest folds down at the push of a button and the table lowers, so the whole area becomes a sunbed. Forward of that there are galley units on both sides, a helm under its own sunroof and a companion seat. Below deck the saloon has an L-shaped seat, a galley and two cabins.

- Two sunroofsOne over the cockpit and one over the helm. Both open at the push of a button.

The S390 packs a lot into a 39 ft boat. The cockpit turns into a sunbed, the two sunroofs open the boat to the sky, and the bow cabana gives shade where most boats this size have none. Below deck there is room for a family, with three beds in the guest cabin. Tracks for a cockpit enclosure let you stretch the season too.
