S/Y Nashachata II - General overhaul 2020

 

Over the last 8 years of sailing, we have hosted more than 1,100 sailors, sailed 97,000 nautical miles and spent 18 thousand hours in 110 consecutive sailing stages. Nashachata has combatted extreme weather conditions and very demanding high altitude regions in the Arctic and Antarctica.

 

As a result of this very intensive sailing  Nashachata required a general overhaul including the replacement of a significant number of installations. The entire revamp was carried out under the supervision of a British inspector from the MECAL office, to ensure Maritime & Coastguard Agency (MCA) certification requirements of code  "0" for Small Commercial Vessels were met. Code  "0" accreditation provides unlimited shipping, including commercial and polar regions. Having achieved such demanding requirements, the yacht guarantees supreme levels of both safety and sailing comfort.

 

During the first stage of the renovation, the engine and all the tanks were dismantled to facilitate precise thickness measurement of metal sheets and the structural control of the hull. Despite a mature age of 23, the hull is in perfect condition and hull sheeting have sustained 99.9% of original thickness. 12 layers of paint were coated in a shipyard in England - the precision in painting plus the additional protective  layer of "wax" (applied in particular to the under water tanks)  have ensured maximum protection against corrosion in an aggressive marine environment.

 

As a part of the interior hull body renovation, cleaning and varnish was supplemented in targeted corrosion areas  and whole hull interior sheeting  below the waterline was subject to three additional coats of paint. The mast step was replaced, the tanks reinstalled, and only then were new floors with the supporting structures mounted. All through hull valves were replaced and an additional independent engine cooling system installed. After disassembly, the engine was completely renovated, the pistons, valves and cylinders replaced. The engine compartment has been covered with a new fireproof coat and equipped with a new extinguishing system. The engine received a new electrical installation and  switchboard, allowing for additional control over operating parameters from the steering column.

 

As a part of the overhaul, all installations i.e. fuel supply, bilge, water supply, electrical, hydraulic for bow thruster and autopilot were changed to new systems. Four new AGM batteries with capacity (480Ah/ 24V) have been installed. The steering column was disassembled, all bushings replaced and the shaft re-machined. Propeller shaft bearings were exchanged and a new shaft braking system installed. Additional B&G electronics, including a new autopilot AC12 computer with Triton 2 control and HSE 60  GPS compass were installed.

 

The yacht's interior received heartfelt attention during renovations to provide maximum comfort and high-class solutions  the forepeak being redesigned and two new berths, providing the opportunity of alternative usage. The entire interior, including all cabins, was revived, the upholstery in the mess refurbished and pristine cabinets fitted in the galley and bathrooms.. An upgraded air heating system based on two independents Eberspacher Airtronic D4 Plus units was installed. A new central heating system based on the Refleks central diesel furnace was installed as well as a new 24V LED lighting system.  All cabins have now been equipped with USB charging sockets. Further investments include electric shower drainage pumps, an advanced gray water system in the galley which meets the premier ecological requirements and allows gray water to be collected through a connector in the deck. The anchor bed and the position of the windlass were modified, the chain moved to the crash chamber, freeing up a lot of space in the forepeak.

 

Meanwhile on-deck, 4 winches (Andersen 67 and 72) located in the cockpit have been replaced, while the mast underwent a major overhaul replacement of rigging parts and was repainted. Rollers were renovated and a new mast rope organizer crafted - based on Antal equipment. The deck, sides and underwater were repainted  and teak panels partially replaced in the cockpit.

 

Each sail underwent maintenance at Sail Service, including small repairs. In terms of rigging, some ropes were replaced and new Antal deck blocks installed. The boom spinnaker has been restored.

 

Nashachata secured positive recognition during stability test procedures and received full documentation acknowledging eligibility to be navigated in extreme weather conditions.

 

With respect to safety measures, new 12x Crewsafer 290N pneumatic life jackets were purchased, as well as three new SOLAS A class Zodiak life rafts. A state-of-the-art satellite communication system Iridium LT-3100S GMDSS has been installed  which meets  the SOLAS A GMDSS (Sea Areas A1, A2, and A3) requirements. Nashachata passed sea tests in November and December 2020. For the winter of 2020/2021, the yacht was pulled ashore for service in the port of Jastarnia. In March 20221 we expect to pass final MCA certification and the go on the water.
