Your stern wake somewhat shows that youre skidding but that is best viewed from the cockpit looking back.
The large slack sag in your forestay from what I can see in your video is definitely excessive ... probably the prime reason for the skid and the 'heavy helm'. The very first frame in the video shows absolutely NO jib luff except the very bottom of the tack section ... all the rest has greatly sagged behind the view of the mast.
What your probably feeling as weather helm is the skid's side pressure on the rudder.
At the end of the video the leech of the jib seem VERY tight (probably hooked up to weather) which kind of also suggests and supports the too loose headstay.

I'll try to find some geometric sketch / sail plan of the 36.7 and calc for you what the backstay tension should be to arrive at a 12-15% forestay tension. Is that one or twin backstays?

Nice boat !!!! good video. ;-)
