Hi
Really basic question here – I’ve just been trying to re-step my mast on my series 2 duffin – I’ve been doing a complete strip down and overhaul, so also removed the two bolts from the mast track. I read here https://www.sailboats.co.uk/media/datasheets/gp14_tuning_guide.pdf that the most aft mast track bolt should be 2845 mm from the rear of the transom – so I’ve duly put this bolt there. However – the tenon at the bottom of my (Seldon) mast – while about 6cm long, has a ‘cut out’ section in it – splitting the tenon into two sections – one (aft) roughly 2.4 cm, the other roughly 3.6 cm. My question is this – is there a purpose to this cut out? should it be placed over one of the bolts (either the fore or aft one) – or should I ignore it and place the fore bolt as near to 6 cm away from the aft bolt as the holes will allow and slot the whole tenon between the two?
Hope that makes sense – thanks in advance for any wise words
