Having raced a 2000 against Argos and an Argo against 2000s, I can safely say the Argo is somewhat slower. Whilst the weight and length are similar, the hull is more flexible, the rig smaller and the main lacking the same power. Nice boat, though - the only one of the bigger roto boats I'd say that about, really, though I've not sailed the Quest enough to have an opinion.

Hi,

Glad you sorted out the centreboard problem - I suspect it's easy to just ad another strip rather than dig out the old ones!

Sail training centre I worked for had Argos - sailing with Jib and Mainsail was fairly pedestrian, ir's a heavy dinghy so it doesn't accelerate quickly, but is pretty stable. The Genniker, however, is huge! It seemed to be larger than main+jib so using that downwind will make a huge difference to the PY rating.
The Argo is part of the Topper products - their brochure give PY = 1095. There's no information on the RYA site.
The Argo is used for lots of training - perhaps it's not used for racing that much.

Agreed, though I think it is still useful as a starting point for a boat with no published PN. My spreadsheet actually predicts the Blaze at 1001, 32 less than it's actual numbers but the Spice comes out at 926 so only 4 points below it's last PN (which is IMO about 30 points too low). When I get the time I'll put a few more two handers into the spreadsheet and see where they end up (FWIW it predicts 1047 for the Vago when it's last PN was 1074). I suspect the general upward creep in PNs means that an annual adjustment to the formula will be necessary. Mostly though it's just a bit of fun (just like handicap racing).

Those numbers maybe a bit generous but I think around 1100 would be a good starting point if you can persuade your race committee...

* Just looked at the RS Venture (bigger) and Quest (smaller) and Great Lakes give them 1080 and 1130 respectively so 1100 seems about right for the Argo.

The Fuller number is only valid for conventional singlehanders.  Use it here at considerable risk!

The only PY I found after extensive searching was one at 1075, and one at 1090. Having sailed a Laser 2000 for years, I would put it around that kind of performance, but I have no proof whatsoever, it's just a feeling, and I have no idea how one would arrive at a calculated figure.

The PY system has next to nothing for the Argo. Not even enough to make a suggestion, well, between 1200 and 1250 is as far as I would go. All you can do is to make a list of vaguely similar boats and try and slot it in. Length is the most important factor by a mile, then weight and sail area.

I found loads more packing strips in the slot than there should be, replaced it with new strips, and it now works perfectly.

I'm now looking for any tips on tuning, mast rake in particular. Once again, I cannot find anything on the web, and there seems to be no Class Association, so I don't know if it has a PY. any help on this would be welcome!

Thanks so much for the replies, I’m going to have a go at removing the centreboard next week, will report back as to what I find.
