The Standard CM245 built using epoxy resin infused composite E-Glass, 80-130kg/m3 Foam core achieving optimal weight and strength. Carbon used extensively in locally reinforced structural areas.

  • The Carbon CM245CR built using epoxy resin infused composite Carbon, 80-130kg/m3 Foam core achieving optimal weight and strength.
  • Externally-spray finish Awl Craft 2000 / Alex seal in light solid colour of choice / Anti-slip/ Anti-fouling barrier coatings.
  • The CM45 is primarily designed for the purist and adventure cruiser racer sailor who wants an efficient fast performing sailing design that is spacious due to its open plan saloon and cockpit.
  • Designed as a lightweight owner cruiser racer or for the performance charter owner.
  • Keeping the structure at a low optimum weight is due to a strict build process achieved from many years of experience building light weight multi-hulls using the resin infusion process where it counts getting the optimum wet out ratio every time.
  • The hull is infused in a female hull mould in a 3 stage process by doing this allows us to use a core that has no infusion grooves or resin channels to feed the resin which increases the resin content. The first stage being  the outer skin which is infused in a first stage on to the epoxy primer coating in the mould. The second stage the core is carefully tailored and vacuumed in place with the optimum adhesive resin, once cured the core is then long boarded prior to the final internal laminate is stacked and infused. The advantage of infusing the final internal laminate instead of wet lay-up and bagging is that we will not have creases and folds  in the fibre which does not allow the fibres to load evenly therefore not getting their full benefit.
  • This superior finish is a key factor to reducing the weight of the hull and deck structure as we fair and paint the majority of the internal surfaces. This does add many man hours however we prefer not to pay the weight penalty of panelling to cover up the internal hull.
  • Due to the reduced to weight of the main structure along with carefully choosing gear we are able design an efficient fast easily driven hull.
  • Bows are long slim easily driven with A-symmetric hulls flared inboard giving the important reserve buoyancy when driven hard reducing the hulls from burying at high speeds with larger waves action.
  • This has also provided additional volume in the forward cabin.
  • Centre of buoyancy is located slightly aft of the centre of the hull length with the weight concentration strictly located closer to mid ships by shifting forward the inboard shaft drive diesel engines reducing the pitching motion at sea and giving the optimum hull rocker.
  • Water and diesel tanks located mid ships below cabin soles just aft of the mast lowering centre of gravity with additional fresh water ballast tanks aft of transom for trimming the bow up for downwind legs.
  • Angled inward carbon dagger boards are standard.
  • The bridge deck living area has been shifted aft with the bow section proportionally lengthened with a shorter over hang at the stern reducing bridge deck slamming.
  • Forward double bunks are located lower in the forward section of the hulls due to the additional space available with the A-symmetric bow section.
  • The Saloon and cockpit measures 5.4m in length and is designed to be open plan with a 1.8-2m wide cockpit door way opening, designed with removable modular dinning tables allows versatility by moving the furniture and removing items for racing regatta’s and versatility for charter work and entertaining.
  • The boom has increased in length with the main sail track on the transom beam for maximum stiffness and optimum weight saving. The increased boom length increases sail area and reduces the mast height and lowers the centre of effort improving the stability/righting moment.
  • Reducing the weight reduces the mast height and sail area for its length. All of which reduces weight aloft and improves the stability.
  • The hull free board is kept low to reduce wind age and importantly reduces excess weight.
  • The cross beam is curved for increased stiffness but more importantly it increases the wave clearance when pressed hard under sail.
  • The steering positions are versatile as they can shifted inboard when the helmsman wants  shelter from the elements and outboard for optimum view looking down the centre line of the bows and with 360 degree view over the cabin top from the raised step.
