Re: Stus-List C Polars Again

I sail on a reservoir in Colorado. It has neither tides nor currents nor seas :) Except for powerboat wake, which makes the lake choppy on calm days. And the occasional wind-driven whitecapped waves when the breeze is really up. Cheers, Randy - Original Message - From: "Jeffrey

Re: Stus-List C Polars Again

Perfect. Btw, depending on where you sail, your Speed over water won't ever match. By doing the math between the two you can determine how much current you are in and with some calculations how much that is setting you off course. Food for thought. On 9/27/2016 7:46 PM, RANDY wrote: Speed

Re: Stus-List C Polars Again

Speed over ground - the SailTimer App uses GPS to calculate speed. And it's showing about 0.75 - 1.0 knots faster than my onboard transducer-based speed instrument. Since I trust GPS more, I'm now calibrating the onboard instrument to match the speed shown by the app. I scrubbed my bottom a

Re: Stus-List C Polars Again

Add a dirty bottom at this time of year and they'd work for my boat too. :-) Are you using speed over ground or speed over water for your baseline speed? -- Cheers, Jeff Nelson Muir Caileag C 30 Armdale Y.C. Halifax On 9/27/2016 6:24 PM, RANDY via CnC-List wrote: Those are

Re: Stus-List C Polars Again

Those are a reasonable approximation but they're from a 30E, the European edition of the 30, which has a different design from my MK I (e.g. reverse transom, different interior, probably different displacement), and who knows what sails and what kind of prop etc. That boat is apparently fastest

No problem Bill. Since we're back to this, I've appended the polar data (in CSV format) I got from my SailTimer Wind Instrument and SailTimer App this past weekend, as promised. Needless to say, I think this data is wrong, for reasons discussed below. For example it shows I can reach hull

Re: Stus-List spreader lights - do you use them?

I only use mine dockside at night when tidying the boat after a sail. Cheers, Randy - Original Message - From: "Dreuge via CnC-List" To: "cnc-list" Cc: "Dreuge" Sent: Tuesday, September 27, 2016 8:46:12 AM

Re: Stus-List spreader lights - do you use them?

Dave, I have not used my spreader lights while sailing(yet), but I have used them many times for social activities mostly while docked at my marina but also sometimes while at anchor socializing with a large group. That said, I normally anchor over night limiting my light and noise pollution.

Re: Stus-List C Polars Again

Thanks Randy, That is a sweet page, Thanks for Sharing. I was able to make a .csv and import it into the e-95, (I used the C Polars). Unfortunately it will probably be next spring B4 I see what it does for my Dynamic Vectors/Laylines. Bill Coleman C 39 Erie, PAanimated_favicon1

Re: Stus-List spreader lights - do you use them?

At night we have headlamps on. We will light up the sail with the white light. Spreader lights would be nice dockside, but otherwise I would have no use for them. I don't like making holes in spars, so my default is less stuff. Joel On Tue, Sep 27, 2016 at 9:37 AM, Della Barba, Joe via

Re: Stus-List Spreader lights

Hi, My previous C had spreader lights and I used them before the advent of cheap, reliable, LED headlamps. My current boat has a deck light under the steaming light and I don't use it. One nice feature of ether deck or spreader is that you can light up the boat in an emergency. If you do

Re: Stus-List Freeze/thaw issues in lead keels

For the record - those are not photos of windstar! The one that is really bad was a 33-2 and it piqued my curiosity so I went for a walk with my camera. I did have the waterlogged keel stub issue, which I fixed, and I then bedded and epoxy/glassed over the keel/hull joint, faired with

Re: Stus-List spreader lights - do you use them?

I don’t have them to use, but my steaming light does a fair job lighting up the foredeck. If there is some kind of tangled up mess with a chute or something we might turn it on to see what is what. Traditional spreader lights are good to make your boat visible to others if needed or cleaning

Re: Stus-List spreader lights - do you use them?

One other thought to mention: if you’re sailing at night and want to confirm that another boat sees you, you can light up the sails pretty effectively using the deck light, as well. Fred Street -- Minneapolis S/V Oceanis (1979 C Landfall 38) -- Bayfield, WI > On Sep 27, 2016, at 8:23 AM, Marek

Re: Stus-List spreader lights - do you use them?

The only time I ever used my deck light was when I docked late in the evening (at dark) and used the light when clearing the boat after the sail (putting on the main sail cover, coiling all lines etc.). Possibly you could use it when sailing if you have some major sail change coming (but then a

Re: Stus-List spreader lights - do you use them?

Dave — I’ve got the LED combo deck/steaming light I replaced last winter; and yes, I do occasionally use it to light the deck at night. More often when sailing at night, I’ll use a red LED headlamp, though, to save night vision. — Fred Fred Street -- Minneapolis S/V Oceanis (1979 C Landfall

Re: Stus-List Freeze/thaw issues in lead keels

Will second Bill's comment. Two years ago a C 37 was in our boat yard for the winter with a keel that was not well attached to the keel stub. The keel nuts would not tighten but slipped on the bolt threads. Dropped the keel to discover the bolts had not been sealed at manufacture allowing bilge

Stus-List spreader lights - do you use them?

Good Day all, Set Windstar ('85 33-2) on the hard yesterday, mast down. A rewire of the mast has been on the to-do list for awhile. I noted (again) two long-unused conductors poking out of the mast below the lower spreaders. No light fixture, but there is a labelled breaker in the panel. I
