Size of rope determined by fittings on boat. Do you have horned cleats, spinlock or Barton fittings to make fast main halyard ?

Self tacking or conventional jib ? Again diameter of fairleads , clamcleats or spinlocks ?

Alloy or plastic head board. Bottom hole on headboard used to align halyard with sheave. See attached photo of current fitting.

Mast track needs to be well lubricated. Suggest Sailkote Drylube.  Sorry for abbreviation. Last attempted post seemed to be blocked by spam filter as we are still up a mountain abroad !

Sorry, can't recall rope Ds.

But I do recall
1. Upgrade to Dynema for both halyards.  Makes a big difference to the ability to flatten, and keep flat, the furling jib in strong winds, and maintains rig tension. My original halyards, and shroud-end lacings seemed to be elastic!
A dyneema main halyard ensures that the cunningham remains effective in high winds.
2. Buy a longer main halyard than you think you need, as that horrible sharp, angry little block at the mast head cuts the main halyard. The sharp alloy sail headboard doesn't help.
You can then shorten off the damaged mast top end as needed, and make the rope run last longer.
 I brought just enough the first time, and soon regretted it.
3. I found Rooster "Polilite sheets" to be effective on the jib. They don't self-tangle like cheap braid on braid, but are not too expensive.
You may have your own preference?

Launched just over two weeks ago, boat on river mooring since...at least two named storms and several gales later....
First Sail yesterday.
Managed a mile out to sea in a very lumpy SW, gusting 20 knots + so gave up and went home....fed up. That was supposedly the third race of our Spring series, but the first actually run. Only Four starters, just two finishers.

It's rained for weeks, so much that even South West Water's pathetic reservoirs are ALMOST full, so they say on the news!
Meanwhile, In our Victorian home, it's always damp to some degree but the dehumidifier upstairs has run constantly  for weeks, unable to get humidity  below 50%. I've fitted a drain hose so that it runs directly to the bathroom  floor drain.

Today, spent a glorious morning out at the far side of St Austell Bay, in Yacht club tender (22ft Plymouth  Pilot motor lauch) in order to lay the semi permanent seasonal  race marks. That chore done we were "rescued" by the Fowey lifeboat as part of their Sunday morning exercise,  boarded and then towed part way home. Good fun all round, and a worthwhile  trip in a flat sea, light S winds and sunshine.

SURELY the season can finally start now!?!

But at least one more blow to come...45 knts WNW forecast tomorrow! See attached...

Forecast for South Kerry is for dry weather, but lousy cold, 11 - 12° C. https://www.met.ie/weather-forecast/sneem-kerry
I will launch in the coming week, can't wait.

I don't know about the rest of you but around these here parts (Dublin Bay) it's been either piddling down, blowing a gale and often both together. I haven't even been down to the yard to fit my bilge pump because it's rained every single day since I can't remember when. Sometimes showers, other times a deluge lasting the whole day. Very windy most days. 

I can't even fish; the rivers are all high and coloured Sob!
