When the mastic between the teak boards cracks / splits I presume that it is sensible to fix it to prevent water ingress? If so should one remove all the cracked mastic or merely put some new mastic into the cracks?

My boat had some splits in the black caulking between the teak on delivery and this was fixed during commissioning but has since reappeared (same place or new? not certain). I don't think this is a problem as the split is in the caulking. My teak is not varnished so it can dry out anyway.
When it was repaired initially the shipwright removed the caulking where it has split, primed the area and reapplied the caulking using black Sikaflex.

I also leave my teak au naturelle as I think it looks best that way ( and is less work)
I feel better if the cracked mastic has only cosmetic relevance - my private worry was that water would get under the team and loosen it / Damage it
As we don't get freeze ups here in Tasmania I would have thought that it was a lesser issue here than in colder climes
It needs fixing for cosmetic reasons and I'm happy to cut the damaged old stuff out and resikaflex

Aroha,
if the problem is on the deck then i would fix it asap bec otherwise you may get water seepage into the core which will then eventually rot the core. If the problem is on the seats in the cockpit then not so urgent but best to fix it before water gets in, freezes and then lifts the teak.
