1. The forestay is fitted with a stout torsion-resistant lower toggle (see fig. 9.2). This is attached to the stem-
head fitting. The toggle can be fitted either athwartships or fore-and-aft.
2. Check that the stem-head fitting and the toggle are suited (see table below). The stem-head fitting must
be able to withstand a torque of 1200 Nm for Wire Ø 16, Rod 40 and Rod 48, or 1600 Nm for Rod 60
(Maximum working load).
3. Check that the drive unit goes free of the pulpit, bow anchor, or other deck equipment. (See fig. 9.1 and the
table).

4. Protect the hydraulic hoses an through-deck fitting from the anchor chain.
5. Siting of the through-deck fitting is to your choice. Send measurements A and B to Seldén Mast AB or your
dealer. We will then make up the two hydraulic hoses for the motor. See fig. 11.1 for the through-deck fit-
ting dimensions. A Ø 72 mm hole through the deck is required.

Through-deck fitting

The drive unit and hydraulic motor are tested before delivery.
The hydraulic motor is a Danfoss OMM 20 cm3/revolution. Maximum recommended pressure, p=140 bar.
The oil flow, Q=20 litres/min. gives a nominal speed n=40 rpm.
The normal working load when reefing or unfurling is p=40 bar when Q is 19 litres/min.
A 24-volt hydraulic pump unit with an effect of P=3 kW is usually sufficient.
Through-Deck fitting
The main installation dimensions are shown in fig. 11.1.
Quick couplings
The quick couplings (fig. 11.2) are disconnected by pushing the knurled coupling sleeves out from
the coupling. The coupling sleeves have safety locks to guard against involuntary disconnection.
These are freed by twisting the locking rings until they release.
Always check that quick couplings are locked!

Hydraulic hoses
Hydraulic hoses for installation below deck are1. not supplied. (See fig. 12.1).
Connecting threads are G 1/2”. (See fig. 11.1).2.
Use hydraulic hoses of good quality corresponding so SAE 100R7/-ISO3949.3.
Minimum dimension 1/2”. Minimum working pressure 140 bar. Minimum recommended bending radius
150 mm (6”).
Put suitable marks on the hoses where they connect to the quick coupling. If they are crossed over the opera-
tion of the hydraulic motor will be reversed.

Important! Blow through all new hoses with compressed air to clean them from possible dust
and dirt before fitting. Check the system very thoroughly during assembly to ensure that no
impurities are present.
When disconnecting the quick coupling, always apply the protective covers and sleeves
supplied.

The sail
The sail should be made for rolling up on the starboard side of the
luff foil.
Any sun-strip should therefore be on the starboard side of the sail.
A high cut clew can give a constant sheet angle even when reefing.
The luff tape ”hard line” should end above the sail feed. (See fig.
31.1).
We recommend webbing on both the head and tack.
Wire head pendant
Sail with a luff more than
500 mm (19”) shorter than
the maximum luff length
should be fitted with a
permanent wire head pendant.
The pendant and sail luff
together should not have a
total length exceeding the
maximum permissible luff length.

Luff extrusion
The sail luff should slide very easily in the groove as friction
increases very greatly over the whole luff length.

Notes/Comments

Notes/Comments

Important points to remember before sailing
The sail rolls on to the starboard side of the luff extrusion.
The halyard angles out 5–10° from the forestay with sail set.
All sails used have the right total luff length. See page 31.
No lines or halyards can get caught in either the swivel or sail.
The tack ring is in the right position. See page 20.
The winch handle is not in the drive unit when that is out of use. It will rotate very fast if the sail
is rolled in or out.
The by-pass valve is correctly set when operating manually.
The quick couplings are properly locked. Look at page 11.
