Custom 39

General layout:
The hull is divided into 3 watertight zones separated by steel bulkheads:
- large locker in the back with two hatches
- large locker in the front with hatch (where we store sails and anchor chain)
- living space in the middle
Dimensions/physical data:
- Draft: 2.31m/7.57ft
- Beam: 4.01m/13.16ft

Construction/plan: Ralf Osborne, Sweden
Shipyard: Jerzy Urynowicz, Szczecin, Poland (1995)
Helm: Tiller
Engine: Mercedes OM615 60 PS / 44 kW, 1994; dual-circuit
Fresh water: 3 stainless steel fresh water tanks, 1000L in total
Diesel: 1 diesel tank 1000L + 100L in the small tank in rear trunk (switchable)
Berths: 1 cabin with double bed, 1 other double bed, 1 single bed, 2 kid beds (1,60m)
Rigging:
- Sloop type
- 1 mast (18m) with 4 shrouds on each side, 2 backstays aft and 2x2 spreaders
- 3 forestays: 1st forestay up to masthead with furler, 2nd forestay at a distance of about
20 cm from the 1st one, a 3rd forestay (length 12.3m) for small sails.
- Boom: 5.2m
- 2 aluminum spinnaker poles, one extendable.
The most important steel cables all have a diameter of 10mm and are therefore extremely
strong. The standing rigging was checked in December 2023 and the aft lower shrouds (port and
starboard) and the third forestay were replaced (12/2023).
Power supply:
- We renewed most of the on-board electricity (12V) in 2023 (planning and renewal by a
professional).
- There are two 185 Ah service batteries and a smaller engine battery.

- Energy (around 1000 Wh per day) comes from 5 solar panels (3*100, 2*70).
- The two smaller panels fill the engine starter battery, while any excess energy is
redirected to the service batteries. The 3 large solar panels go directly to the service
batteries. Two solar regulators are installed accordingly. One of them is equipped with
Bluetooth, enabling the electrical system to be monitored via an app.
- There are two 230V sockets, which can be connected via a 2000 W inverter or via the
shore power connection.
- Batteries can be charged either by shore power, solar panels or the engine alternator (we
fitted a new 50A alternator to the engine in November 2023).
Navigation equipment:
- Aries windvane gear with spare parts
- SIMRAD Robertson AP11 autopilot
- GPS (Furuno GP-32) and VHF radio with DSC (new, 04/2023) at the navigation table

anchor alarm and collision alarm

- 2 depth gauges (one at the navigation table, the other one in the cockpit)
- Anemometer on top of mast and display in cockpit (wind direction + strength in knots)
- Display in cockpit to show on-board computer‘s screen. But most of the time we
navigate with Navionics charts on the smartphone, as all AIS data is transmitted to the
smartphone via WIFI.
Safety equipment:
- 1 Plastimo liferaft for 4 persons (new, 12/2023)

Cockpit:
- Removable teak benches + various cushions
- The benches are 1.9 m long and 50 cm wide
- Instruments at the front of the cockpit: Display of anemometer, depth gauge,
temperature and engine speed, VHF radio.
- Storage locker below the tiller
- Storage lockers on both sides
- 4 winches

Interior layout:
- 1 cabin with double bed in the front
- 1 double berth on port side at the back
- 1 single berth on starboard at the back
- 2 kid beds (or storage spaces) amidships/front starboard
- Navigation table with small bench mid-starboard
- Large dining table with lounge area and good outside view (large windows), mid-port
- Galley area with sink (we've installed water filters so you can drink water from the tanks
without problems), three-burner oil stove and oven, induction hob, sandwich maker,
coffee machine, 12V electric cooler with adjustable temperature, cutlery, plates, cups,
stove, saucepan and other miscellaneous cooking utensils.
- Bathroom with toilet (Blake Gosport), washbasin, mirrors, storage space and upward
facing porthole.
- The floor is made of large planks that open easily, so that the bilge and underfloor
facilities are easily accessible.
- The hold is dry. The walls are insulated with insulating blankets (glass wool or similar)
covered with a tarpaulin.
- There is a diesel heater with several small radiators distributed around the boat, but we
never used it (we never had to).

Sails and navigation:
- 2 mainsails, 2 furling headsails, 2 genoas, 3 jibs of various sizes (with hanks), 1 staysail,
2 exactly symmetrical headsails.
- There are 3 winches on the mast and 4 winches in the cockpit. We decided not to put too
many lines in the cockpit, but theoretically it's possible to manage everything from the
cockpit. Currently, halyards, boom tows and reefs are handled from the mast. The
sheets, vang and boom brake are operated from the cockpit. The windvane gear is also
controlled from the cockpit. The autopilot can be operated from both inside and outside,
as it is located at the top of the companionway.
- Even with a lot of wind and high waves, sailing remains pleasantly stable thanks to the
boat's weight.
- The autopilot and windvane gear work perfectly, so we rarely steer ourselves.

EOS history:
EOS was built in 1995 for the 1st owners (a german family of 2 adults and 2 children, hence the 2
children's beds), who toured the world with EOS in 7 years.
The boat underwent a complete overhaul before we bought her in the Canary Islands.
We bought EOS in July 2022, sailed a lot in the Canaries, made final preparations and then
crossed the Atlantic to the Caribbean via Cape Verde.
EOS was hauled out again in July 2024 in Grenada to redo the hull paint (sandblasting, primer,
antifouling).
