FORE BEAM AND BOW SPAR BUILD AND ASSEMBLY PROCESS
The forebeam and bow spar are both made from foam/glass CNC panels with unidirectional carbon tapes to provide strength and stiffness to resist the rig loads.
The two components are built separately. The bow spar is open at the top and is fitted up to the fore beam by cutting a notch in the sides of the spar after the fore beam has been installed. The joining of the forebeam and the spar is completed while the top of the spar is open, and the longitudinal integrity of the spar is repaired with carbon tapes.
The standard bow spar terminates level with the bows at the waterline and does not require any brace wires. This Raku 44 is being fitted with the extended bow spar which will be braced to the inboard sides of the hulls.

The hull shoes for Raku 44 #1 were built with foam/glass strips over mould frames as shown below. For Raku 44#2 Magma Yachts built a solid male mould and infused the laminate over the mould.
The strips were cut from full length panels which were infused full length in VE resin with Divinycell cores. Using broader strips reduces the number of glue joins but finer strips create a fairer surfaces that requires less sanding and less filler.
Note that the king plank (the full length plank just above the opening) has been carefully aligned along the bilge curve, and then the planking line has been reset below the bilge curve. This is so that none of the planks will have to cross the bilge curve at an angle that would induce twisting in the planks.
