I am bringing this topic in here as it is an ongoing topic that deserves attention.

 

Blue Lagoon Marina Open Regatta
 

For a few months now we have been running Open Class boat races in the North Sea as well as a few other class events all using the North Sea Olympic course.

Apart from this being a fun event, it is also a means to help refine the boat handicaps that we have up until now.

The virtues of the North Sea Olympic course
This course is a standard Olympic triangle (sailed as a triangle and a sausage) a course that offers 2 upwind legs, 2 reaches (one on each tack) and 1 downwind leg. it is the fairest possible course you can sail for a number of different boats. NS Olympic chart (link)

How have handicaps been calculated
To calculate the different boat Handicaps, we have used the M-24 as a standard. It has been decided that the M-24 is a middle-of-the fleet boat and all other boats' average times are measured against the M-24's average time.

The existing Handicaps have been calculated in a number of Hotlaps course locations (Plum Gut, Sulu, Hepurn etc.). Each different boat's average time has been compared to the average time of the M-24 on the same course.

Handicap = (M-24 average time / boat average time)

Then the handicaps for all areas have been averaged out and we have used those handicaps for the Open Class regattas.

What we have now done is to use the North Sea Olympic course times and add them to the existing handicap data. The interesting thing about these times is that they are made under racing conditions and over this standard Olympic triangle course.

North Sea Olympic Handicap Calculation (Google Docs Spreadsheet)

Handicaps for each boat have been calculated on the North Sea Olympic course. Where more than 10 results are available for a boat, the top 10 results have been used to get a better quality set of data.

On the Best Times tab, you can see that:

  • The M-24 is in the middle of the fleet which confirms its use as a Standard to use - a good thing
  • The standard deviation with the new handicaps is decreasing - also a good thing
  • I have added the new handicap for the North Sea and the General handicap which is an average of all areas including North Sea.

On the General Handicap Averages tab, you see:

  • The old handicaps calculated from the Hotlaps courses from the different areas.
  • The new handicaps calculated by adding the North Sea Olympic course results to the combined average handicaps.

Notes:

  • The new handicap for the Quest-2m v2.0  = 0.82 (higher than the 0.74 handicap of the Q-2m v1.0 and as expected)
  • The new handicap for the Pacha 110 = 1.11
  • Handicaps going up: WildWind OP-60, Trudeau Patchogue II
  • Handicaps going down: Nacra 17, Wildcat-45, Bandit 25 R, RM Clever

A question: As we are only sailing Open Class regattas in the North Sea for the moment, do we apply the North Sea Handicaps to future races, or do we apply the General Handicaps (averaged over all regions)?

I will update these figures when more data comes in. If you feel that any boat has been given a tough handicap, then lets race a series with the boat to get some good times.

Please feel free to comment and correct me if any of these figures are wrong or miscalculated.

Just tidied up the table. Moved the Nacra-17 and the Wildcat-45 to Class 2 (closer times to those boats than the ones above in Class 1) and then resorted Class 2.

Tidied up the table again (changed commas to points e.g. 0,79 to 0.79) and revised the handicap for the Trudeau Leetle Cat II from 0.48 to 0.55.

The WW is Wild Wind. Is the the other The Mesh Shop? I'm assuming this. These were the names coming from the old Hotlaps tables.

Arya, it's the WildWind VOJ-70, which is no longer available for sale in-world nor on the marketplace. The last time I saw it sold was maybe 2011 or 2012? It was a wearable-design boat. Had a small platform with several pose balls and the sail you rezzed, and then wore the hull (which was about 80 prims). Came in two color versions: and orange/yellow hull and a blue with white hull. I can show you mine in-world if you ever want to see it.

The wildwind vendor in the little mall on Dex was selling a lot of the older builds not that long ago, I picked the ACJ-90 back in February.  Sadly, it seems that the vendor now only sells the OP-60 and the AC45, even though you can see lots of other goodies in the vendor when the edit it :(

Oh wow, kaliska. I didn't know the vendor in Dex had old WW items as recently as this year. I think I had gotten everything corry had done back when it was released, but friends would have been happy to pick up some of the older stuff... the RCJ-44 especially!

heh, must remember to proof read before hitting that post button XD can't type for toffee

 

I grabbed the RCJ-44 in January too :)  Oh, and the TR-30 in Feb.

 

Got quite some way to go to beat the number of boats in your inventory though!
