About this tender

Riva mare - what we know.

The Rivamare 38 is the modern successor to the Aquariva idea: a 38-foot Riva built around guest-aware day cruising rather than long-distance passage. We tend to position it less as a working tender and more as a guest amenity. It is the boat that an owner of a 50-plus metre yacht would specify to ferry guests between marinas, anchor for an aperitivo, and act as the visual signature of a programme already running serious utility tenders elsewhere.

The hardware is honest: 11.88m on a 3.5m beam, twin Volvo Penta D6-400 DPH sterndrives, 40 knots top speed, 31 knots cruise, gyro stabilisation that reduces roll meaningfully at rest. Single cabin below for two, which makes the boat usable as a casual weekender at marina hops without pretending to be a real overnight cruiser. Fuel capacity in the order of 1,000 litres gives credible range at cruise.

What earns its place on a programme is the brand language. Riva woodwork, polished steel detail, and a hull profile that draws attention in any marina without trying. Owners use the boat as an experience for guests rather than a transit asset, which is the right way to value it.

Highlights

Built for the work.

The four details we'd point out first to a captain who hasn't seen one on the water yet.

01

Twin Volvo Penta D6-400 sterndrives

Twin Volvo Penta D6 400hp sterndrives at 3,500 rpm give the Rivamare 40 knots top speed and 31 at cruise. Sterndrive at this size is the right call for a day boat: better trim authority, simpler garage interface than a shaft installation and a transom kept clean for swim platform use.

02

Gyro-stabilised at rest

Riva specify gyroscope stabilisation as standard, which reduces rolling at rest meaningfully. For a boat that spends real time at anchor while guests swim or dine, the stabilised feel converts the cockpit from a sea-state environment to a usable lounging deck and is one of the reasons charter feedback on the boat tends to be strong.

03

Single cabin for casual overnighting

One cabin below for two guests, rather than the studio illusion of a smaller day boat. It makes the Rivamare a credible weekender at marina hops without forcing the brief to be more than a sport day cruiser. The bathroom and cabin volume are usable rather than token.

04

Brand-defining presence

Mahogany interiors, polished steel, lacquer and the unmistakable Riva profile. On a yacht programme the Rivamare earns its keep partly as a guest experience, partly as the visual signature when the mothership is at anchor. Few day boats hold their value or their charter appeal as reliably.

Questions, answered

Before you enquire.

Is the Rivamare a credible superyacht tender?
It is not a working tender in the sense of a Ribeye RIB or a SACS Strider, and we would not recommend it as a primary transfer asset. It earns its place as a guest amenity boat on programmes already running utility tenders. For owners who value a brand-defining day boat that carries the Riva language, it is the obvious specification.
How does the gyro stabilisation perform at anchor?
Riva publish a roll reduction figure in the order of 70 to 90 percent at rest. The practical effect is that guests can move around the deck and dine without the rocking that defines smaller open boats at anchor. It is the single feature that converts the Rivamare from a fast sport boat into a usable anchor-out lounge.
What is the realistic range at cruise?
With 1,000 litres of diesel and a 31-knot cruise on twin D6-400 sterndrives, the boat delivers comfortable range for marina-hop day cruising. For longer transit legs owners drop to a more efficient cruise speed in the low-twenties, which extends range meaningfully. The boat is not designed for ocean passage and the brief reflects that.
Can the Rivamare lift into a yacht garage?
At 11.88m by 3.5m the Rivamare is too large for almost every yacht garage and is normally specified as a stand-alone boat moored separately or carried on deck of a much larger mothership with proper crane handling. On most programmes it lives at the marina rather than the garage, which is consistent with how owners actually use it.

The yard

Riva

Sarnico, Italy

Riva is the yard we place at the top of the tender shortlist when visual impact carries as much weight as the spec sheet. Founded in 1842 by Pietro Riva on the shores of Lake Iseo in Sarnico, northern Italy, it is one of the oldest continuously operating boat builders in the world. Since 2000 it has been part of the Ferretti Group, which funds the engineering department and the long-standing design partnership with Officina Italiana Design - the studio behind every Riva hull since 1994.

Production runs across three Italian sites: the historic Sarnico yard handles models up to 21.0m; La Spezia covers the larger flybridge and sportfly range; Ancona is home to the fully custom steel-and-aluminium Superyacht Division, established in 2014. The current catalogue spans open, sportfly, and flybridge families from 8.0m to 90.0m, with the Superyacht Division extending the offering to custom projects at 50m and above.

In the tender and chase-boat segment, the tender range runs from 8.0m to 17.0m. The 11.88m Rivamare 38 is the model we see most often specified as a formal yacht tender - GRP hull, twin Volvo Penta D6 inboards, 40 knots top speed, mahogany and stainless detailing throughout. The 17.0m Rivale 56 steps up to twin 1,000 or 1,200 hp MAN V8s, cruising at 34 knots in its higher-output form. What distinguishes a Riva tender from functionally comparable hardware is finish consistency: high-gloss mahogany, teak decks, and mirror-quality lacquerwork that hold the yard's surface standards against any comparable Italian production builder. We'd put it alongside Pershing and Wally on finish, at a price point that makes the decision straightforward for captains whose programme requires a tender that needs no apology at a superyacht marina.
