Sweden Yachts C34 Avia

Sweden Yachts C34 – Classic Scandinavian Craftsmanship

The Sweden Yachts C34 represents traditional Scandinavian boatbuilding and the timeless design of late 1970s sailing yachts. It’s not the fastest upwind cruiser in the archipelago, but when the weather turns rough, it performs excellently without needing to reef the mainsail. The newly designed radial-cut furling genoa also handles well when reefed.

Since acquiring the boat in 2020, we’ve extensively refurbished and upgraded it. A complete deck renovation was carried out, during which the original balsa core was replaced with foam core, and Flexiteek was installed. The project is fully documented, and a PDF description is available via this link.

Structural Integrity

This yacht features a robust chainplate structure. Under the side decks runs a steel beam to which the chainplates are attached. These beams are bolted and laminated to the bulkheads at both ends. The structure was confirmed to be completely rust-free during the renovation. Photos are available in the aforementioned document and in the gallery below.

Interior

The interior has been carefully maintained. New mattresses and upholstery were installed in 2021. The forepeak mattresses are thicker than standard and include removable, washable toppers. Both the forepeak and aft berth mattresses have a thick mesh underneath to prevent moisture buildup.

Woodwork has been treated with furniture wax and was last varnished in 2018; it remains in excellent condition.

The galley features a Dometic Moonlight-TWO stove with oven. The aft locker in the cockpit holds four 2kg gas bottles, with a fixed gas line running to the stove. The main valve behind the stove was replaced in 2025, and the system was pressure-tested—documentation is available.

The stainless steel freshwater tank holds approx. 180 liters. We’ve only filled it with municipal water, so it’s safe for drinking. The tank has been cleaned with citric acid and treated with Klorite a couple of times, followed by thorough rinsing.

The boat sleeps six: two in the forepeak, two in the aft cabin, and two on the saloon sofas, which convert into a wide berth.

Storage is ample, with a hanging locker and shelf cabinet in the bow, and a wide hanging locker aft. Numerous lockers and compartments provide excellent storage throughout.

The saloon layout feels spacious, with the aft berth located behind the sofa end, separated by a partial bulkhead. The mast is positioned at the end of the saloon sofa, not interfering with table space or movement. The head is roomy and features a Dometic electric toilet installed in 2018.

The longitudinal galley is practical, and the fridge compressor was replaced in 2024 with a model featuring a cold accumulator inside the box.

Electrical & Navigation Systems

The boat is well-equipped with electronics and features an STNG network. Tacktick wind, speed, and depth data are integrated into the STNG network via Raymarine Microtalk and displayed on Triton displays and the plotter at the pedestal. There’s an Axiom 9 on the pedestal and an Axiom 7 on the companionway hatch, which operates as a standalone unit.

The electrical system has been significantly upgraded. A 200Ah LiFePo house battery is charged by a 150W solar panel with a new Victron MPPT controller. A Victron DC-DC charger was also installed. The engine alternator is 100A and handles DC-DC charging to the LiFePo battery without overheating. The starter battery is a 75Ah AGM, connected to the bow anchor windlass, which is always operated with the engine running—AGM handles the load well.

The shore power charger was also replaced during the LiFePo upgrade and is now a Victron Phoenix Smart IP43 Charger 12V/50 (3).

The battery status is monitored by a TBS Expert Modular battery monitor with a 600A shunt. Additionally, all Victron chargers are Bluetooth-enabled and can be monitored via a mobile app.

Raymarine AIS700 transmits and receives; MMSI and vessel data can be updated via Raymarine software on a Windows laptop using USB.

The VHF is a Navicom RT-1050 with touchscreen, also on the STNG network. MMSI can be updated by the user.

Above the spreaders on the mast, there is a Qspot antenna box and a Teltonika RUT360 4G router with Wi-Fi. With a Telia SIM card, coverage has been excellent throughout the Baltic Sea, enabling remote work from the boat. Power is supplied to the router via a 12V PoE box, with an Ethernet cable running down through the mast and the injector located at the mast base inside the cabin. 

Engine

The boat is powered by a Nanni 29hp diesel from 2004, with approx. 1800 hours. It has been regularly serviced and is highly reliable. We’ve logged about 100 hours per season, so it should serve well for at least another 20 years. The drive unit is an S120 with a 2-blade folding propeller.

The stainless steel fuel tank holds 80 liters.

Sails

The sails are in good condition. The mainsail is from 2017, with two reef points and four battens. The genoa is a 105% cruising laminate sail, radial-cut and custom-designed by Neb Sails for this boat. It performs excellently both upwind and in the narrow channels of our archipelago, even when reefed on the furler.

During the deck renovation, the genoa track positions were adjusted, allowing for optimal sheeting. For downwind sailing, the boat is equipped with a spinnaker/gennaker setup, including a removable stainless steel bowsprit.

The mainsail balances the rig well on this masthead-rigged yacht. Upwind performance was further improved with a full-width Harken traveler across the cockpit, offering strong control and locking ends.

The spinnaker is old but usable. The gennaker with a sock is currently onboard but included only by separate agreement.

All halyards are in good condition. The mainsail halyard is Dyneema. There are dedicated halyards for the spinnaker/gennaker (to the masthead) and a lower halyard guided by a fairlead for the jib. The boat also features a self-tacking jib track and the option for a Solent stay (100% Dyneema), allowing a hank-on jib to be sheeted to the self-tacking track.

All lines are led to the cockpit, with small winches for easier hoisting and new rope clutches.

A Rodkick was added in 2021.
