Gold leaf, mosaic floors and reproductions of Gustav Klimt's paintings now float down Europe's waterways. Uniworld's newest river ship, S.S. Emilie, is a deliberate tribute to the Viennese artist, right down to her name — Emilie Flöge was Klimt's lifelong companion and a noted fashion designer in her own right.

The ship follows Uniworld's one-off design formula: every vessel in the fleet is individually styled to echo the destinations it sails through. On board Emilie, that means a shimmering gold-leaf lobby, jewel-like colour schemes and bespoke furnishings that translate Klimt's decorative style into a contemporary take on Viennese luxury.

She's an intimate ship by design. Just 154 guests spread across 76 suites and staterooms, from Classic and French Balcony categories up to eight 26-square-metre suites and a 38-square-metre Grand Suite. As with all Uniworld cruises, the fares are genuinely all-inclusive: gourmet meals, premium wines and drinks, and daily shore excursions come standard. The practical upside is obvious — you pay once and spend the rest of the trip watching vineyard-covered hills slide past from the sun deck or nursing a drink in the brocade-style bar.

S.S. Emilie will work across three itineraries. The 10-day Vineyards & Palaces along the Danube with Prague combines the Wachau Valley's wine country with castles and historic cities — including an evening at Clam Castle, where the Count personally welcomes guests into a family home his line has occupied for over 500 years. Spitz and medieval Regensburg feature along the way.

The eight-day Castles Along the Rhine runs from Switzerland through France and Germany to the Netherlands, with stops in Strasbourg, Cologne and fairytale Rüdesheim, plus visits to Rheinstein Castle and an Alsatian food-and-wine detour where French and German traditions collide.

Then there's the eight-day Classic Christmas Markets cruise, from Nuremberg to Frankfurt in December. Rothenburg's half-timbered old town hosts one of Germany's oldest Christmas markets, and the ship doubles as a warm base to return to after evenings spent browsing stalls for handcrafted gifts and gingerbread.

This is river cruising aimed squarely at travellers who want boutique over big. With fewer than 160 passengers, no queues for the buffet and design that actually relates to the region outside the windows, it suits couples and culturally curious travellers more than families. If you've been tempted by European rivers but put off by mega-ships, this end of the market is worth a look — and the all-inclusive model makes budgeting refreshingly simple.
