Wightlink - last season's league runner up - had a thoroughly bad weekend as they lost the Solent derby 5-6 to near neighbours Solent Devils 5-6 the night before.
Chieftains lead the South 1 table two points clear of second placed Streatham Redskins - who won 1-7 away at Solent on Sunday - and with a game in hand.
Invicta Dynamos move up into third place after a 4-point weekend that saw them win 3-9 away at Cardiff devils on Saturday and then 2-1 at home to MK Thunder on Sunday.
Thunder remain in 5th place despite a winless weekend that also saw them lost 2-1 away at bottom club Oxford City Stars on Saturday.
