ParticipantHi – so I have a Mk2 duffin GP14. When I bought it it came with 2 mainsails – both from ‘speed sails’ – one is a standard racing main- the other is a fancy kevlar job, that I never use.
My problem has always been that I’m the only GP14 where I sail- so I’ve never had any other boats to look at /compare (other than finding pictures on the internet)
I’ve never been happy with how the mainsail looks/rigs. So today I had some time to do some measurements – the boat didn’t have any ‘black bands’ when I bought her – she does now – measured from the GP14 association spec – one on boom, one at the gooseneck, one in the right place at the top of the mast
So – two, related problems – basically
1) there’s no way that the clew of either sail will reach the black band on the boom – even really tugging on the outhaul doesn’t get there and anyway – the sail just looks awful when you overstretch the foot
2) There’s also no way the sails will hoist to the top blackband on the mast – well – you can get it there before you attach the boom to the gooseneck, but at that point the mast end of the boom is actually stuck pretty firmly forward of the mast, and will not tug back or down to get attached to the gooseneck
You can solve both problems by not putting a pin through the eye of the tack – so that the tack is basically flapping free both higher and more aft than it should be – but this doesn’t seem right either!
So my assumption is that the sails are probably old/out of shape – though this would surprise me with the kevlar one – as it looks really quite unused – however its possible that the ropes in the foot and the luff have shrunk? and this is causing the problem?
Basically I’m about to buy a new sail – but i don’t want to do do and be faced with the same problem – so thought I’d check on here for advice – is this a common problem with older sails? – or is there something really obvious that I’m doing wrong? – I’ve played around with the job tension a bit (all of the above was at 400lb) – if i tug it on a bit more it makes a tiny difference to being able to move the boom nearer the gooseneck – but nowhere near enough..
All thoughts gratefully received
Dave
