Sailing Yachts - Halyard Mount

Echomax reflectors use a symmetrical arrangement of interacting corners. Whilst its centreband response pattern is maintained at 15° tilt RCS is -5dB. To counter this, and avoid 'mast shadow'.

Pass a bight over the yardarm via a dead eye. Return bight through reflectors eye and secure taking lines through bight. Take tails through reflectors bottom eye and then to separate cleats via loops at --xx--.

IMPORTANT

Yachtsmen will be aware of the need to trim the reflector when on the reverse tack, failure to do so will result in compounding the angle of heel rendering the reflector inefficient.

Note: Reflector trimmed to leeward 15°. Mast heeling to 30°

Echomax may be fitted in any position around the mast (i.e fore or aft).

Hypothetical figures on mast shadow may be viewed

Utilising Echomax stainless steel mast brackets (available separately) fit reflector as high as possible on the mast, using Monel or stainless steel rivets (3/16 x 1/2" 4.8 x 12.7mm). To avoid electrolytic action use zinc chromate paste between bracket and mast or closed cell foam tape. Firstly fix top bracket to mast in the required position, measure distance vertically between centres, mark position of lower bracket then drill and fix. Use two stainless steel hexagonal bolts 8mm dia x 30mm long to fix Echomax to the mounting brackets

There is also a deck bracket available separately for mounting to a flat surface.

EM230 Midi Basemount

EM230 basemount suitable for direct installation on wheel house roofs, RIB A frames, marker buoys. Robust four hole base fixing and supplied with fixing kit comprising of spacers to avoid over tightening and neoprene washers to absorb the shock of crashing down on waves at speed.

Chosen by the RNLI as best reflector for their fleet of 400 RIB's. After capsize tests and exhaustive sea trials, the Midi recorded 100% paints at 3.8 miles and 80% paints at 5 miles plus in sea state 'fair' although mounted only 2m above sea level. (RORC/ORC recommend 4m above sea level).

Available with optional factory fitted Lalizas DOT all round white or tri-colour navigation and four meters of cable or Hella LED 360 navigational all white light with 1 meter of cable – just bolt on and wire up!

Fitting kit included with the EM230Midi Basemount

Midi Basemount is designed for A frames, pole mounting or base mount with suitable base for fixing on wheelhouse roofs. Use four 10mm stainless steel bolts of the appropriate length at 80mm PCD. It is essential that 17mm stainless steel washers are used to spread the load between the bolt head and the Echomax flange mount base. As Polyethelene is subject to very slight expansion or contraction due to temperature changes periodical checking of the fixing is advised.

Shown below are a range of brackets available separately, suitable for use with the Basemount
