About this tender
Anvera 58S - what we know.
The Anvera 58S is a 17.5m chase boat from Anvera, built in Misano Adriatico, Italy: twin 850hp surface drive, 53 knots and 16 guests.
The Anvera 58S is the build we ask the Italian yard for when a programme needs a platform that can genuinely do both jobs: high-speed chase and on-water hospitality at the same address. At 17.5m on the waterline with a 5.12m beam, it sits at the top of the Anvera range, evolved directly from the proven 55S and carrying the same construction philosophy into a larger, more habitable hull. Twin MAN 850 hp engines driving Top System surface propellers put credible speed numbers on the table - over 50 knots by the manufacturer's own published claim - without the weight penalty that a GRP or aluminium boat of this size would impose.
The structure is where the 58S separates itself from most Italian performance craft of comparable length. Anvera manufactures and laminates its own carbon fibre, combining unidirectional and multiaxial plies with high-density PVC core and epoxy resin throughout hull and superstructure. The result is a boat that is materially lighter than any equivalent GRP platform, which means the twin-engine installation can be sized down without sacrificing performance - a meaningful advantage when it comes to fuel burn on passage and crane loads when recovering to a mothership.
We'd put the 58S alongside a Frauscher or a Vandutch 40 when a captain asks what to consider for an owner who wants real overnight capability in a chase boat. The two lower-deck cabins and dedicated heads compartment, a 1,600-litre fuel tank, and 400 litres of fresh water give it genuine multi-day range without resupply. The folding stern terraces - over 23 square metres of deck when deployed - mean the boat converts from transit mode to beach club in under a minute at anchor, which changes what a programme can offer to guests.
Anvera's background in Class 1 offshore racing shapes the way the 58S is built and finished. The aerodynamic superstructure - shaped around two 12-metre airfoil risers enclosing the helm, deckhouse and cockpit cover - is a direct expression of that DNA, as is the stepped hull bottom that underpins the speed and efficiency figures. For captains evaluating a chase-boat order, it is worth noting that Anvera positions the model as eligible for commercial certification under rigorous standards, which broadens the operational envelope considerably when the owner's programme crosses into charter territory.
