Yes, I had no time so far to do a public news-item.
The Swan was my favourite project, so I spent some time in testing.
But the thanx go as always to Tom, who designed it.

It is a spectacular model - our club did a over one hour plus in it last night and we all still finished within a minute of each other. We had to let Camster win though - you know how the Scotsmen are when they lose

While Tom's earlier models were not exactly what we were after I compliment Tom and his assistants that his X-332 and his SWAN 45 - they are simply a top effort that the guys at the Virtual Yacht Squadron are racing and want to race !

Some of the best models yet !

How about some templates ?

Is it me, or it sails better upwind in port tack than on stb?

Check it again to see if there is not current affecting your pointing ability. I thought the Moth did that. (Still not convinced that it doesn't) I haven't noticed it with the Swan, though.

I think the problem lies with the Hood sails... I'll switch to North...

Kwasi · Post by **Kwasi** » 13 Dec 2006, 12:24

I can tell you, that the mathematical formula in the excel sheets for the polars just is mirroring the values from one tack to the other one.

That would mean, that IF there were different speeds, they would reslut out of a Nadeo bug somewhere.
Howevere I don't exspect that.

I'm seeing close to 2 knots differential between tacks. Granted, that could be caused by current, as I haven't formally tested it. Best place to test would be to race it, not the polars, unless the polars are generated downloading speed / angle information directly from the boat, which I don't know if it is possible (but seriously doubt).

BTW, I'd put the Swan right next to the ACC'07, TP-52 and offshore, my personal favorites, so don't get me wrong....

Hi Guys

I am sorry to say.. there is a diffrence between the tacks.
I have tested the boat on a course with out current and wind changes.
In f7 you see the diffence the most. There is about 1.5 knots diffence between port and starbord. Best BS is on port where i am going as fast as 15 knots. On stb i cant get it over 13.5 knots.

P.s still a great boat

I have seen this reported with regard to other custom boats, and I suspect that the vpp files are all made up using the same spreadsheet. This is completed on one tack only, and it should mirror the parameters to the other tack automatically. It is always possible that there is a bug in the spreadsheet, but I have never thought to check. I will do so when I have a spare minute.

Lol, this problem made me crasy when i was working on ACC 07!!
Solution : Value in the file heelcoef.txt must be between 0 and 1, not more.
I'm pretty sure you have increased heel on upwind with some value bigger than 1...

By the way, if you still want to increase heel on upwind, Matai (working on the new open 60) found something very interesting recently :
you can add a <heelcoef> for each sail. And this coef can be bigger than 1.
