Can I widen the beams of the Narai Mk IV?
The Narai Mk IV can be widened. To do this safely the crossbeams would need to be made somewhat deeper in cross-section, to carry the extra strain. You could use the beam design for the Tiki 46, these beams have a slightly different cross-section and are therefore, though bigger, not much heavier.(These beams can still be mounted to the hulls exactly the same as the original beams, the covers over the beam-trough will need to be made slightly higher to allow for the greater beam depth). If you would like to buy this beam design, contact our office at info@wharram.com for plan sheet prices.
