Mainsail Centre Sheeting

I've little experience of the Contender but I remember that you have to go along way aft to tack the thing and the bum drags and the boat stops.  I'd rate it close to zero on the roll tacking scale.

take a hacksaw to your tiller extension. lol

Seems folk aren't interested in posting the numbers, never mind save me some work.

The factors I would look at for "roll tackiness" would probably include waterplane area distribution (ie whether the boat is fatter in the middle than at the transom) rise of floor both in the midle and at the transom, how vertical the topsides are, rocker amount and distribution and so on.

for instance if you compare a Merlin with a modern Cherub, both are equally flat floored in the centre but the Merlin has more rocker, much less vertical topsides - thus more buoyancy further out when the boat is heeled, more rise of floor further out and the waterplane much more towards the middle of the boat. Some of those differences will be related to what's different in "roll tackiness" between them, some not...

Here's a very crude and stylised representtion of how differently the two sorts of shape float when heeled.

Ents are amazing to watch in the light stuff when they roll tack. It seems if they try it in anything over a light breeze it turns in to a roll over tack though....then they do the titanic impression.......

We have a guy in a British Moth at our club, he always seems to struggle on the roll tacking, but given the size of the rig he just ghosts along nicely in the light stuff! Anything more than a F2 and he is toast though (he is quick in the fleet, has been Nat champ at least once and runner up several times).
