Re: Jeanneau Attalia

How many hours did you spend? For me it took about 75 hours.

Wish I could take credit but we had a local guy do it in the yard. I'm not sure how long it took him but 75 hours sounds about right.

Re: Jeanneau Attalia

Ok, so we go sailing last weekend, a long weekend . while on the hook in clear azure blue water, I decide to go look at my shiny bronze propeller. Could not find it... It was completely covered in barnacles!!!! These little guys don't waste their time. I was able to scrub them off with a scouring pad but it looks like everything needs some kind of anti fouling.

Re: Jeanneau Attalia

OK,

So we went racing the last two week-ends. We have one of the smallest boats in the fleet. I am new to racing so the whole rules of racing thing are a work in progress (When cruising, I just tend to avoid boats on the water).

The crew is new to sailing for the most part but everyone is getting the hang of tacking, gybing and hiking on the rails. Timing is getting better. I have original sails (1983). The mainsail is probably still fine but the Genny is "baggy" so needs to be either recut or replaced. My issue is boat speed. What can I expect in 10-15 kts (race last week-end)and in 15-20kts (this past week-end). She sailed really well balanced, the hull (and keel) are fine (just redone). We had a current against us on part of the course but the speed according to the GPS gave us from 4.5 to 5.5 for some of the time and 5.5 to 6.5 (which seemd OK). Only once did it briefly tip over 7. OK, so the waves are on the bow for the upwind leg (but only 1-2 meters or so these last two weeks). What gives? Marty, Jens?

PS winds were from the east, here is the course: the longest leg of the course is the tack up to the eastern-most mark, which is also against a current and against the waves and the run on the way back (but we have no pole or spinnaker so that was annoying). http://www.barbadoscruisingclub.org/...EGATTA2013.pdf

Re: Jeanneau Attalia

Issue i see is you are using gps speed! so if you are going 4 knots on one leg/tack, but 6 on the other........do you have a 2 knot current against on the slow, so 4 knots plus 2 knots current equals the 6 knots on the other leg. Or the other leg has 5 knots boat speed plus one knot current. Other leg is 5 kntos boat speed less one knot current.

Reality is here, you need to look at the knot meter, NOT the GPS as your only measure of speed. GPS will tell you over the ground, knot meter tells you actual water speed. As noted, over the ground can be different than water speed!

speed for me is in the mid to upper 5's, sometimes low 6's for 10-15, 15-20 depending upon the sail up, can be over powered with a 155, and need to go to a 140 or a 155 with a reef. upper 5s and lower 6's upwind, surf into the low 8's down wind, with 6 pretty consistant. I can usually do .5 knots boat speed per knot of wind down wind to a degree.

You might also check the mast center same with spreader area. are the spreaders the same ht to the deck on ea side. along with is the tension on the shrouds correct. Not to loose etc.

Re: Jeanneau Attalia

Dear Mark
On my home page Attalia 31 32 Trud jenskondrup.dk you will find a polar diagram for the Attalia - that gives you some idea of what can be expected in boat speed from different speeds and angles of wind. I got it from a French Attalia site theat seems to have been closed.
In my experience, the Attalia is very sensitive to waves because of its large beam - so do not point too high in waves above 0.5 m.
Good luck.

Have anyone had the same (brand) propeller that I have? If so is, do you know what type of shaft it is? Straight or cone formed? If cone formed - how cone formed, 1:10, 1:20 or another dimension? (The boat is in the water for the moment, so I can't take the prop away at the moment. Would like to take her up first when I have the new prop.)

Have anyone, who has the same engine as I, changed to a folding propeller? What is a good size of a folding propeller, according to the engine and the boat?

/Virgo
Not sure if you are still looking here, but found the original prop from my Arcadia, it is a 360x180mm or 14x7 rh with a 22mm shaft. The previous owner put a 14" max prop. But the shaft was switched out to a 7/8".

Not sure what this does for folks.......

Re: Jeanneau Attalia

Jens,

I looked at your polars, real similar to my arcadia. That must be why here in the states, there is not much difference in ratings under phrf, 3-6 secs a mile. SWAG under ims/irc .87 vs.88 or something that close.
