The rigs are supplied ready to have sails fitted.
All three rigs use 11 mm diameter x 0.6 mm wall black or silver, high-tensile aluminium mast sections and your choice of Sailsetc black or silver rectangular boom sections.
The A rig mast has 16 mm forward pre-bend rolled evenly from the head to 900 mm below, the B rig mast has 11 mm forward pre-bend rolled evenly from the head to 600 mm below and the C rig mast is without prebend. With all three rigs, the back-stay can be tightened without or with the mainsail mounted, removing this pre-bend or any induced bend, to achieve a perfectly straight mast. On Plan B yachts, A, B and C rigs generally use the forward shroud positions at the deck.
Spreaders of the A and B rigs are bespoke from 3 mm diameter aluminium. The C rig is without spreaders.
The jackstay-style mainsails are cut to suit a straight mast or one with only very little aft bend.
Shroud heights, jib-boom pivots, mast pre-bend and mast rake are combined to give a rig that will automatically adjust to wind gusts, freeing and flattening both jib and mainsail in harmony. This allows the correctly trimmed yacht to sail close-hauled to windward, in balance, needing only minimal helm correction.
The mast has a plain, cylindrical plastics step. In the hull, the mast-step base is flat and parallel to the waterline. This allows the mast step angle to be tuned to the rake used, helping to keep the lower mast in column.
B and C rigs have internal mast corrector weights, to bring them to a nominal A rig weight.
Fittings are a selection of Sailsetc commercial and Plan B bespoke.
