The Tempest 850 Open Hair should be configured starting from the plants actually declared, not the sum of the photographs. The official card indicates 8.50 meters, 3.25 meters of glare, 16 people, about 1,900 kg dry and 400 hp maximum. The open deck is completed by marina toilet with septic tank, refrigerator, fresh water and electric anchorage. This guide transforms those data into technical and contractual controls.

This table serves as a match base. The seller must associate the single boat with documents, engine, accessories and capabilities actually installed. The values “about” should not be transformed into more precise certified measures. Also the approval for 16 people does not imply that every layout of the bridge is comfortable at full load: it is necessary to check seats, hooks, storage of individual devices and distribution of the masses.
First verification: identity and documentation
Check identification number, declaration of conformity, plates, manuals and correspondence with the contract. The limit of 400 hp must be respected by the amount of the installed power. For a used specimen, invoices, coupons and interventions should be acquired on the tubular; for a new, orderly configuration and delivery minutes. Each accessory not in the standard list must appear with a brand, model and warranty conditions.
Basic electrical system
The electric panel is standard, but the board does not detail the number of batteries, switches or circuit diagram. These elements must therefore be verified on unity. Open the accessible rooms, check labels, protections, visible tightening and separation from water and fuel. Turn on utilities once at a time, then together, annotating falls of anomalous tension. You should not deduct the capacity of the system from the presence of switches in consoles.
Bench 220 V
The 220 V dock grip is optional. If present, you need to ask for schematics, protections, chargers and installation statement. Check connector, cable, differential switch and correct circuit separation. If it is not ordered, the boat remains devoid of that function even when the port offers current. The contractual point is simple: “predisposition” and complete plant are not the same thing and must be described without ambiguous formulas.
Automatic bilge pump
The automatic pump is included in the standard. The control must reach the lower area, identify pump and automatic control, remove any debris and follow the exhaust pipe. A controlled test confirms start and outflow; manual ignition from the picture is not enough to validate automatism. Also note accessibility for maintenance and presence of persistent water, which requires search for the cause instead of simple emptying.
Fuel: 390 liters approx
The declared tank is about 390 liters. Inspect mouthwash, vent, visible pipes, indicator and control access. Odours or traces should not be normalized. The capacity does not allow to promise autonomy, because there is no certified consumption, reserve, conditions and load. The verification sequence must include an initial reading, a documented supply and a prudent calculation based on the engine actually installed, not on a promotional configuration.
Fresh water and shower
The shower with about 60 liters is standard. Try pump, control, flow and seal of fittings; leave the plant under pressure to detect spontaneous start-ups. Check draining of the shower area and possibility to empty or sanitize the tank. The volume is intended for rinses and services of the day: every estimate of duration depends on habits. During the remittance, we need procedures against stagnation and frost where applicable.
Marine toilet and septic tank
The toilet with septic tank is listed among the standard equipment and finds place in the undercover compartment. Check access, ventilation, pump, pipes, valves and emptying options according to local rules. The system must be tried with clean water, without ignoring smells or strains. It is important that the contract clearly distinguishes installed components, capacity not declared by the page and equipment necessary for the unloading or aspiration.
Refrigerator approx. 48 liters
The standard refrigerator is indicated in about 48 liters. The verification involves the supply, fixing, ventilation and accessibility of the fuse, as well as the actual cooling. Lighting it a few minutes does not show the ability to maintain the temperature during a hot day. Ask for manual and absorption of the installed model, then evaluate the available electric reserve. The presence of the appliance does not allow to invent the number or capacity of the batteries.
Verricello and anchoring line
Electric winch and bow roller in fiberglass are standard. Check control, electrical protection, fixings, anchor compatibility, roller and chain as well as drainage of the stem. The card does not specify length or diameter of the line: they must appear in the delivery. Try ascent and descent safely and ensure the presence of an independent system that retains anchor during navigation, without entrusting everything to the reducer.
Hydraulic Government
Hydraulic steering is the standard. A stop motor control stroke, fluidity, games and visible patterns; with unit in water verify response and centering according to the procedures of the system builder. The page does not declare servicing, so it should not be given by present. Pipes, fittings and cylinders must be identified and accessible. Any change over the delivered configuration must be recorded with components compatible with the installed power.
Outboard motor and power
The maximum limit is 400 hp, but remain to be defined brand, model, relationship, propeller, tools and commands. The verification sequence must compare serial engine, documents, hours, maintenance and alarms. No speed is published by the official page used, so a commercial data should be accompanied by test conditions. For use, they serve diagnostics and history; for the new, delivery protocol and proper integration with government and framework.
Performance: Test method
The description generally speaks of high performance but does not provide consumption or speed. A reliable test records people, fuel, water, accessories, wind, wave, regime and propeller. They are observed entering the planata, response to controls, visibility and presence of vibrations, without transforming impressions into certifications. Comparison only makes sense between equivalent sets. The conclusions must remain limited to the proven specimen and the conditions noted.
Orca pipes 1670 dtex
The declared material is Neoprene-Hypalon Orca 1670 dtex. Check cold pressure, valves, joints, abrasions, discoloration and repairs. A difference of pressure after exposure to the sun is not enough to diagnose a loss: temperature and times must be comparable. Colours, glued accessories and any interventions are indicated on the contract. In the used boats, a well-documented repair is more valued than a cosmetically uniform but history-free surface.
Covers and coatings
The Flexiteek on longherons is standard; the one in the cockpit is optional. Check therefore that the estimate does not attribute the same nature to the two surfaces. Examine edges, adhesion, joints, stagnation areas and temperature in the sun. The prodier sunbathing kitchen is included, while an additional poppiero sunbathing kit is optional. For each pillow check fixings, drainage, seam status and volume necessary for storing.
Shadow, roofs and protection
Bimini, storage cloth and console and bench covers are separate options. Specify size, fixing points and mutual compatibility. An open bimini can interfere with accesses or poppiera structure; a cloth must allow ventilation and proper outflow. Photographing the complete assembly at the time of delivery helps to avoid disputes. It should not be assumed that a visible cover in the official image is included in the basic price.
Radio, ski pole and pulpit
Radio, ski pole and stainless steel pulpit are optional. For the radio they serve model, loudspeakers, protections and absorption; for the ski pole they must be verified fixings and limits of use; for the pulpit, continuity of the hooks and interference with the anchor. Each additional installation introduces holes, wires or loads, so it must be performed and documented correctly. The optional list does not prove that all elements can be combined in the same setup.
delivery controls
At delivery check documents, plates, motor, propeller, government, picture, actual batteries, navigation lights, compass, bilge, winch, fuel, water, shower, toilet, refrigerator and ordered accessories. Count keys, towels, pillows, table and manuals. Photograph serials and technical compartments. Each anomaly must be inserted in the minutes with correction period, avoiding generic formulas that make it impossible to distinguish a defect from a never purchased endowment.
Programmed maintenance
The plan must combine requirements of the engine and individual components. At regular intervals check tubular, valves, bilge, steering, water and black plants, winch, batteries, connections and fixations. Fridge and towels require cleaning and ventilation; tanks consistent procedures with stop and season. Recording dates, hours and spare parts transforms maintenance into verifiable history and protects the value of the unit more than a cosmetic preparation before sale.
Recommended configuration for user profile
For household outputs have shade priority, hygienic service, water and food preservation. Those who practice sports evaluate ski pole and freedom of the poppiera zone; those who leave the boat in port can consider the grip from dock, if installed with complete protections. The choice must start from frequent use and load, not from the catalog. A well configured Tempest 850 Open preserves free paths and makes every installation inspectable.
Operational Conclusion
The Tempest 850 Open offers a clear technical base: open bridge, 400 hp maximum, day plants and an optional well separated list. The job of the buyer is to transform the board into a separate one. Only after electrical, hydraulic, documental controls and a recorded test can be judged. This method avoids unsupported promises and allows you to compare quotes or units used on verifiable elements.
