Re: How does in-mast roller furling affect pointing ability?

Pointing doesn't come from the mast. It comes from the leeches and that is the same for every boat. This is discounting consideration of the hull underbody as a relevant factor and looking only at sails.

To put it at the simplest, saggy and soft leeches = bad pointing.

Agreed on the first point - it's the result of having a very tall rig and a SA/D of about 17.5.

However, windward ability is also respectable. It's not a J boat for sure, but it does fine as a cruiser. Per the earlier discussion about instrumentation, I don't really trust mine either, so will not make any claims about degrees and polars, although the exist online: http://www.ftp.tognews.com/ModelDocu...al/Manual2.pdf.

Re: How does in-mast roller furling affect pointing ability?

I have sailed them and sailed beside them with my boat which was decent but also not a raceboat and I was outpointing the boat by close to 10 degrees. I agree that all in all they are an OK sailor and you don't usually want to point all that high offshore anyways so sure, they make a decent cruiser. Maybe not the best choice for a coastal cruiser unless you love paying for diesel.

Re: How does in-mast roller furling affect pointing ability?

My Oceanis 38 with roller furling mast and 105 genoa points across 110 degrees perfectly well, and routinely makes about 60% of true wind as speed over ground.

Perfectly fine for coastal cruising.

It closes or opens tacking angle if the current is from ahead or astern, it lifts/knocks one side or the other if it is from abeam,
If the current is running perpendicular to your course, then you are right. But if it's running parallel, then the angle changes - often dramatically - depending on whether you are sailing with or against the current.

Angle over ground, of course.

Tacking within 60 degrees, as you seem to think you can easily do, is better than all but a very few dedicated racers can do. If actually true, I'm deeply impressed, but I remain skeptical. As I say, a few races could dispel my skepticisim.

Yeah, you might not be getting true angles on your wind instruments. My old C&C 38 with a custom keel (deeper/ shorter cord length, rebalasted) out pointed many J's in it's time and would have been hard pressed to sail that high. The genoa tracks were so far inboard on that boat that it required using a snatch block on the toe rail with another sheet with an S hook to get the headsail to trim well on a broad reach. That was the best upwind boat I've had and it couldn't do that, I know newer designs are better but I'm thinking your instruments might be messing with you.

That's what I said.
