About this tender

Riva Iseo Super - what we know.

The Iseo Super is the boat we point owners towards when the brief is a sub-nine-metre open with the fit and finish of a full Riva and a choice of driveline to match the mothership's programme. At 8.24m LOA and 2,490mm on the beam, it sits comfortably within most tender garages sized for an eight-metre slot, yet it carries six persons and enough fuel for 240 nautical miles at cruising speed on the standard diesel configuration.

Three engine options are offered from the factory. The standard fit is a single Volvo Penta D4 producing 300 hp, which returns 38 knots flat out and 33 knots at cruise. Step up to the optional Volvo Penta V8 350 CE and the top speed climbs to 41 knots, though range at cruise drops to 160 nautical miles on the same 330-litre tank. A third option - the Volvo Penta V8 300 CE at 305 hp - bridges the two in economy terms, offering 170 nautical miles of range at 33 knots cruise. The page also references electric motor options under the broader Iseo range, though published electric-specific data for this Super variant is not itemised in the manufacturer specification table.

Unladen displacement is quoted at 3,100 kg; laden it rises to 4,010 kg - a sensible spread that tells you the hull is not marginal under a full crew and fuel load. We would put this alongside the smaller Frauscher and Fjord day-open tenders in the garage-ready category, with Riva's Italian coachwork and Ferretti Group supply chain as the differentiating factors for owners for whom provenance matters at the dock.

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

Three factory engine options

Riva offers the Iseo Super with a standard Volvo Penta D4 at 300 hp, an optional V8 350 CE at 355 hp reaching 41 knots, and a V8 300 CE at 305 hp. All three use sterndrive propulsion. The spread lets a captain match fuel economy and outright pace to the owner's itinerary without resorting to an aftermarket refit.

02

240 nm range on standard diesel

With the D4 engine and a 330-litre fuel load, the Iseo Super is rated to 240 nautical miles at 33 knots cruise. That is a credible coastal-programme figure for a tender of this size and means the boat can run independently between ports without requiring a fuel stop alongside the mothership every afternoon.

03

Sub-nine-metre garage footprint

An 8.24m LOA and 2.49m beam keep the Iseo Super within the envelope of standard tender garages on yachts from around 45 metres upward. Unladen displacement of 3,100 kg is manageable for most A-frame davit arrangements rated to three to four tonnes.

04

Electric propulsion on the options list

Riva positions the Iseo Super within a range that includes silent electric motor options, sharing the design approach of the El-Iseo. Owners with emission-restricted marina access or a preference for quiet shoreside running have a route to an electric drivetrain within the same hull platform.

Questions, answered

Before you enquire.

Which engine should we specify for a mothership programme that prioritises range over outright speed?
The standard Volvo Penta D4 at 300 hp gives you 240 nautical miles at 33 knots cruise, the longest range of the three options on the same 330-litre tank. If your programme is coastal transfers rather than escort work, it is the straightforward choice. The V8 variants trade range for pace, returning 160 and 170 nautical miles respectively.
Will the Iseo Super fit in a standard tender garage on a 50-metre yacht?
At 8.24m LOA and 2.49m beam, it falls within the envelope of most tender garages sized for an eight-metre slot on yachts from roughly 45 metres upward. Confirm the garage dimensions and davit weight rating with your yard; unladen displacement is 3,100 kg, rising to 4,010 kg fully laden.
Is an electric version genuinely available, or is it aspirational?
Riva positions the Iseo Super within a range that explicitly includes electric motor options, citing the same design approach as the El-Iseo. However, the manufacturer's published specification table for the Iseo Super does not yet itemise electric-specific performance data. We would confirm current lead times and output figures directly with the Riva dealer network before contracting.
How many persons can the Iseo Super carry?
Six persons on board, as stated in the manufacturer's specification table for all three engine variants. This is consistent across the D4, V8 350 CE, and V8 300 CE configurations.
What is the water tank capacity, and is it adequate for day use?
The water tank is 80 litres across all variants. For a tender used primarily as a day runabout or transfer boat, that is adequate. It is not a cruising boat with overnight provisions, so fresh-water demand beyond washing down and drinking is unlikely to arise in normal yacht-tender service.

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.
