Some picts from a relaxing day of sailing

No official race today.. just 20 guys and their boats having fun..
this doesn't show it ...but we had about 10 starts and raced up to the weather marks rounding them to port and back to the downwind marks at he east end , and back to the starting line mid way... Fun Stuff..

Chasing the Rabbit

Had the day off Monday so we had a nice afternoon at the pond playing Chase the Rabbit with 3 other ODOMs and an IOM..

With two weather marks and two downwind marks at the far end of the 200 meter SD pond.. the idea is to race to a finish between the two weather marks .. And the winners of the last race just idle about past the line till the "rabbit" catches up and crosses last. As he does (or some times a bit earlier when we all yell "Turn and go".. ).. he turns downwind to start the next race and we all try to catch him again racing down and back to the gate at the weather end again..

Fun Stuff.. we did this about a dozen times.. I wish I could say i was winning much.. did once, but only cause I had about a 10-boat-length lead at the two downwind marks.. More Time, tuning and practice will likely help tho.. JimS

Since Lon was under powered with. "B" rig on his IOM...
Rich H took almost every one

I'm taking off tomorrow too.. You should try to come down if you can Chris.. We missed you down there.

Dropped in a new rudder servo today

I never felt anything wrong while actually sailing but upon initial turn-on pre-launch check.. noticed a couple times that my rudder servo would sometimes) oscillate / or vibrate/chatter about 1/8th inch (viewed at the trailing edge of the fin) as I was initially turning the stick to the right..it wouldn't do this while turning left, and it would quit chattering after two or three swipes across it's max range of travel to the End Points. So, I decided to replace it with this Digital servo of nearly an identical size..

Also set up Dual Rates at 95% and 50% each initially, and Expo up so I can tone down the rudder response near center when I'm going to be on a single tack for a long time. I'm curious to see how that behaves..and if any of you have tips on generic Dual Rate and Expo settings for your own sailboats?

Already learned tho that I need to switch back well in advance when on a Port tack tho cause I accidentally hit my friend Lon's boat by mistake when I was fiddling with the Expo switch. With D/R on and set for only 30% of it's normal 100% range i turned too slow and late to miss him..

Got my AMYA No. 16982 today

Along with a cool info packed Model Yachting Magazine No 159

there's going to be a points Race Feb 13th at the SD Boat pond. I hope to try racing with the ODOM guys for-real in that event..

Should be interesting.. amazing how few BASIC rules there are, but how many complex situations can come up based on them and all sorts of assorted conditions Id never dreamed of.. That part of this sport is far more complicated than RC sloping.. and it's rather bewildering but I'm planning on winging it any way.

Dual Rates/Expo on RC Sailing

I am not sure I understand the need for DR/Expo on RC Sailing. It is relatively slow compared to RC Model Aircraft. Even at that most that I know of, use DR/Expo on 3D aerobatic planes, if ever at all.

It is probably a good idea to simplify controls, make sure servos neutralize to center and focus on tuning the boat and of course, racing tactics. Filipo can help you.

Hope to meet you someday.

Del,
thanks a lot.. Main reason I was considering them is to simply tone down the ODOM's response to it's rudder.. Seems there are times moving fast and headed to weather especially that I seem to over correct too often with just the slightest touch.. so I think setting some negative exponential around center has probably taken care of this. As to the D/Rates tho, I agree that's probably not needed and I'll likely forget to flip back to Normal /100% after a long downwind run in particular..

As to tuning the boat and tactics... those skills appear to be a lifelong endeavor.. and I'm a long way from mastering either one... if ever.. But I do thank you Del, and yes please do come over and say hello Ok?
Thanks Again..
Regards,
JimS

Mark My words..

It's hard to race without marks.

I don't know the particulars but understand that due to a recent request by the City Parks and Rec folks, the 4 marks we typically have (two on the weather end, and two at the far downwind end of the pond).. Have all had to be removed as they are considered a water hazard but the Power Boat guys I guess.. In any case, I think it's still Ok to set your own marks out there if you pull them in daily after use and it's not a Power Boat Day.. and i am planning to make a couple .. so asking if anyone out there has a good idea on simple materials and techniques that allow for quickly setting a mark with a 12 foot lead weighted anchor line..

Yours in knowing where to go.. JimS

The problem is the same all around the world!

Here are two links showing how we solve it in France (It's in French, but there are many pictures):

First, the making of buoys.

Next, how to set them on water, using a RC boat (the usage of real boats is forbidden on our pond).



Finally, the end of the day:

Jim,

I built race marks out of the foam swimming pool "noodles". I went overboard with mine and cast lead conterweights and attached them to wood dowels with a sliding anchor system that would allow them to adjust to changing tide levels. They could be simplified quite easily for your application.

Rick, i agree, and I may not go that fancy but really like the noodle idea and will wind up doing something very similar I'm pretty sure.. Thanks .. JimS
