SIG 45. Superfast – Made for the Med

SIG 45: The fastest cruising catamaran of its size! Designed for Mediterranean style cruising.

A pioneering concept: Incorporate all major design elements from ocean record braking catamarans to a cruiser. A design brief, that led Hugo Le Breton and VPLP Naval Architects to the SIG45. A stylish full carbon catamaran with an open platform for some serious fast cruising in the Med. After all what do you need a saloon for when you can enjoy the sun and the stars?

Let the sunshine in! (and the moonlight too)


We are talking about a truly fast catamaran. Not another floating caravan….
Enjoy gliding at 8…10…15 kts with ease, comfort and safety. The SIG45 creates in fact its own wind: the more the boat accelerates, the higher the apparent wind gets, which in turn increases sail pressure and boat speed….Experiencing close or even above 20kts is on the daily agenda in the Aegean Sea!
This is how it is possible:
Super powered:
  • Sail area /Displacement 2/3 =  43.00 for upwind (D=5.5t, Upwind SA = 134m² )
  • Sail area /Displacement 2/3 = 78.31 for downwind. (D=5.5t,  Downwind SA=244 m²)

Optimized hulls and appendages:

  • Hull shape optimized for planing both upwind and downwind
  • Retractable daggerboards => minimal drag  + stability
 Super light:
  • full carbon construction
  • laminated high tech sails
  • no superfluous elements
Take a look at the Crazy Polar Diagrams, they speak for themselves:
  • boat speeds almost at wind speed and not only for light winds
  • 20kts with 25kts of wind speed. In the Aegean we regularly get more than 25kts of wind….

Certainly Polar Diagrams are theoretical predictions assuming certain “ideal” conditions (perfect trimming, sails’ conditions, steering etc). However, they do provide however a useful tool when it comes to assessing a yacht’s performance capacity.

Double digit boat speed sensations are now for everybody!


Interior and exterior comfort of a high level


  • 3 double cabins,
  • 1 single bed (for skipper),
  • 2 WC with shower, hot water,
  • full kitchen, stove, fridge,
  • desalinator
  • generator

  • 8.5m large beam (!) and unobstructed deck platform,
  • cockpit shower,
  • diving platform,
  • electric mainsail winch,
  • windlass
  • cockpit table,
  • sun tent
  • aft and front dyneema trampolines

Sailing fast does not have to be uncomfortable!


Absolute safety. Sail relaxed, feel and be safe at all times, no compromise on that!

Safety comes from 5 basic characteristics: Robust structure, Stability, Unsinkability, Offshore design, Speed potential

Robust structure:

  • All carbon hull reinforced both longitudinally and transversally
  • All bulkheads are structurally integrated
  • Extra reinforcement on highly stressed areas of hull and deck (winches, rudder pits, engine etc.)
  • Retractable daggerboards for access in shallow protected waters
  • Hi level construction quality


  • Significant righting moment thanks to its very wide beam
  • Automatic sheet release system in case boat heals more than a certain limit
  • Twin retractable daggerboards for stability and drift resistance
  • Twin rudders inclined to leeward.
    • Always a rudder fully submerged for control.
    • Rudder stands ~vertical => no hydrodynamic lift => steering is always soft and responsive


  • Watertight aft and bow crash compartments

Offshore design:

  • All controls and manoeuvres are cockpit lead.
  • No permanently fixed table that can seriously hurt the crew during rough seas
  • Pilot houses protect from incoming waves
  • Life-raft is stored permanently within the cockpit for immediate access and safe deployment in case of emergency

Speed: Being fast is an element of safety per se:

  • reach shelter quickly
  • escape from a weather front
