RG65 Class General Discussion (RG65)

Hi Guys

Just to let you know that Graham Bantock has just completed a new RG65 design named Rogue, which is listed in his new 2009 SAILSetc catalogue.

Available as a lines plan for home building, and for either swing rigs or conventional.

for more info go to www.sailsetc.com

I may be a bit thick, but I couldn’t find the Rogue on his site or a mention of a catalogue:dunce:
Btw, Maximo Lange posted me a link to Master Boats in Holland with their new Mini Master http://www.masterboats.nl/RG65/RG65.html
It seems that 2009 may see an even biger variety of boats competing.

That was the one that sparked cost question on the RG site. At $200 it was simply a question as to value.

Thanks for the contact for spring clips. You are correct that the weight difference is not worth considering.
What are these things called in German?

The modifications to the ‘Lærke’ I’ve made to create my ‘LARK’ are:

  • Increase the freeboard by 5mm
  • Increase the volume just forward of the keel
  • 3mm narrower widest point
  • 5mm wider transom
  • Flatter aft sections when the boat is heeled
    I’m happy with the result and, although I need to improve my erratic sailing, the boat is performing well. The first real test was at the 4th Regio Cup Süd in Steckborn, where performance seemed particularly good in stronger wind, even with the swing rig, which has surprised many of the other 17 sailors too!
    For lighter wind conditions, I know that the hull is far too heavy and I need a lighter and shorter light wind keel. When not heeled in light wind the waterline width is only a little wider than the narrower designs.
    The biggest problem is that the boat can’t be left alone to sail in a straight line. If you look elsewhere for even a moment the boat veers off course, both upwind and downwind.
    Does any one have any suggestions to help cure this problem, please?
    Thanks
    Phil

Whoops, meant to include this picture too.

I couldn’t find the Rogue on the Sailsetc site either, but there is a mention of a catalogue, although I’m not sure it is the 2009 version which is reputed to includes detail of the new Rogue design.
The link to the new Mini Master at Master Boats worked fine and this design looks very interesting, particularly if she performs on upwind/downwind race courses as they intend.
My first reaction to all this news is that some potentially influential parties in the model yachting word must be starting to take the RG65 pretty seriously. I trust this is good news for future development of the class. Will Brett’s speculation in the opening post of this thread ‘come to pass’?
“Will RG65 be the New IOM”?

My view on commercial builders taking the class seriously is fine, but why do they have to limit it to boats? A couple of well trained fingers to move the sticks on the Tx and a brain transplant to read the conditions better would be far more useful.

388

I have posted an email to Graham to see if perhaps Chris was just a tiny bit “early” on his post. I have a feeling that the new info is in the works and will probably show up on his site after the first of the year holidays are past.

As for commercial builders, they are a boon for those unskilled or not wanting to be builders - but it is also achnowledged the products tend to drive costs up to participate, a lot of small “home” builders are driven out of business because they can’t compete, a lot of sailors “think” they need the latest and greatest - like underwear made from the AC Cup sails which, if worn will make you sail faster. (a joke) :confused: - and the only hope for the class to remain cost effective is that the simpler home-made designs will continue to win and prove that big dollars, carbon fiber, and big-name builders are not necessarily a “sure” ticket to win.

As noted by Martin - time spent sailing and tuning pays much bigger dividends than pay a lot of money for a boat that is dropped in the water and expected to win. Like most sports, the truly good “rock stars” got there by a lot of hard work, stick time, and the ability to pick up the slightest wind shifts… some things you just can’t buy.

Happy New Year

RESPONSE FROM GRAHAM:

[LEFT]Dear Dick,[/LEFT]

[LEFT]The new plan is listed in our catalogue that has been out for a couple of weeks. The website will be updated in the new year. Lines not finalised yet but lines plan price is £20. Postage to USA about £5.[/LEFT]

This would equate to approximately $29.00 for the plans and about $7.00 for postage (U.S. Dollar exchange rate this date)

The Class is growing !!!
and that is good… very good… EXCELENT!!!

Happy new year 2009!!!:):zbeer:

Thanks for the link to a very pertinent thread regarding designing directional stability into a hull. You were quite correct in asserting that it is “Long, but rewarding”. I also have to respect the high level of both scientific and empirical research that people have done over many years and continue to do.
I think the conclusion for me to draw from this thread is that ‘a little knowledge can be a dangerous thing’ and I simply don’t know enough about this topic!
Very interestingly for me though, the two snippets of hull design theory I tried to apply to my project were:

  • from my windsurfing days, remembering that, as a very general rule, displacement hulls with more rocker were quicker in light wind and flatter hulls were quicker in stronger winds,
  • reading somewhere, the very wide transom of the TS2 IOM was a feature to help achieve the designers primary goal of a fast but directionally stable hull,
    and both topics were mentioned in the thread.
    There is clearly far more to this hull designing than meets the eye (well more than met my eye).
    It is, however, very interesting ‘playing around’ on the fringes.
    I will keep on ‘tinkering’ regardless.

OK, now that you’ve digested that :slight_smile: here’s some more you may find interesting:

I have found it very beneficial to pay close attention to what Eric Sponberg writes.

This post by Chris Jackson on the international RG-65 site may be of interest.
Hello UK Skippers

I have just had information that it has been decided to move the normally bi-annual South American event for the ULY-IOM and RG65 class, due by rotation to be held in Chile to this year 2009. We understand that the 2009 event in Chile is likely to be quite late in the year, November, so it gives plenty of time for GBR skippers to save up for an interesting trip.

in turn this move is to allow Argentina to host a first ever world championships for the RG65 class in 2010. This would presumably be in October, the spring weather being ideal for RC sailing, and a venue near Buenos Aires is likely. Again excellent for a combined race and holiday project.

On a more local note there will be an entry on the MYA yearbook for the class, under Affiliated Classes.

Best wishes for good sailing in 2009"

Earl Boebert,

Have you been able to sail your yacht pictured on post #177 again? What are your thoughts on the rigid jib forestay (?) on a RG65. Any more details you care to share in photos?

Thanks,

yar

That boat was scrapped long ago. The latest version can be seen at:

http://www.rcsailing.net/forum1/showthread.php?t=4771

The masthead rig was a failure; the more I cut the jib down the better it sailed, down to 35% or so.

The rigid forestay, and the associated jib radial, is described in the later posts of:

http://www.rcsailing.net/forum1/showthread.php?t=4785

As proven by many instances on free-sailing boats, it works very well. The jib sets nicely and most importantly the boat points well because no part of the jib is to windward of the centerline. Getting the adjustment of the pivot rake right is both tricky and critical.

Cheers,

Earl

Hi all of you:

happens that the SUdamerican Championship was suppoused to be held in november because the worldchampionship was in october 12th, traditional date for the contest. I understand that now that the world championship was moved the Sudamerican came back to its original date, it is october 9,10,11 and 12, in Pucón city, Chile.

This is one of the ost spectacular places for vacations in Chile, plenty of places for raftin, flyfishing, climing the osorno Volcano, , in the middle of lakes area at 750 kms. south of Santiago.

Pucon is a medium size town being its main incoming the tourism. So all of you are invited to come down here, have a nice time sailing and for vacation.

Further news could be track in www.cvrc.cl, Please note that the last time I checked the date for the Sudamerican Championship was not modified yet to october. But it is.

Best regards and hope to see you there.

Please watch the pictures of 2007 Regata in Pucon from German Pica´s blog at http://rg65valdivia.blogspot.com/2007/11/regatas-en-pucon.html

The place is incredible, at the base of Osorno Volcano, surrounded by rainforest, natural thermal swimming pools everywhere, etc. will be a very relaxing trip in deed.

Earl Boebert,
I appreciate the information. Interesting about the masthead jib not working - this informs my ideas for a build. I will be trying the rigid forestay. Thanks for sharing your testing and work and for emphasizing centerline. Do you feel your pivot works the best of available systems for a RG65?

I think it’s definitely better than the traditional swivel mounted boom. I suspect, but have no evidence, that it would point higher than a swing rig but have no experience with them. These little pocket rockets get up to hull speed so fast on the run that I look for advantages in windward work, and at our pond especially in light air. Horses for courses, as always in this game, big boat or small :slight_smile:

Cheers,

Earl

here some photos of My RG almost done!!! Just need some paint and glue the bulb to the keel.
960 grams without paint, ready to sail.
