I thought I would post a list of upgrades which I have done to my boat. This is so that anyone attending the Nationals at the end of June can consider adding them.
Kicker take off improvements - soft attach on boom and bottom of mast (can be done with a loop of dyneema) - very reliable, no metal to fail.
Kicker calibration system - uses a 2:1 calibration scale on the boom for accurate kicker tensioning.
Rudder safety line improvement - Mark 2 only - see Gavin's tips.
Spinlock cleating on halyard - never let me down in 5 years of sailing (Spinlock PXR0206 around £30).
More secure cleating on rudder downhaul using a Spinlock PXR0206 (I had a problem with rudder uncleating and lifting during racing) - it requires a base moulding to match the tiller extension which I got 3D printed in ABS. I could get a batch of these made if enough demand).
Better toestrap (Zhik) - the Hartley one is rubbish. The 'How to' is posted elsewhere in this forum.
Centreboard rubbing strips - worth renewing easy DIY (gives a nice smooth CB operation).
Shroud attachment using eyelets instead of U Bolts (stronger). Probably a nice to have.
Forestay safety line - getting the right length - See Gavin's tips.
Using thimbles instead of blocks (e.g. forestay) - more reliable but you need to re-rig the control line.
Off the boom sheeting - better ratchet action - keeps the cockpit floor clear.
One string bridle using Dyneema (probably needs a 'how to' demo).
Cable wrap around the toestrap tensioning bungee - prevents getting your foot caught between the bungee in a tack.
Improved sensitivity luff telltales (document now on website). Cheap and easy DIY. Better upwind sail trim = better speed
New gooseneck design - low friction, low wear - now available from me (£20). Why would anyone fit the rubbish Superspars one when this is the same price?
Tapered battens - well documented on here. Extends the usable life of a worn out sail and makes the rig easier to handle.
