Antares 760 thread

Only these two bolts holds the tank in my case and both have hole next to it. Hope this helps.

Thanks, good to know, but I am surprised at only two 8mm bolts holding 1/4 tonne of diesel+tank.

I do not know the word "barbotin". 50m of 10mm chain will weigh 110kg compared with 55kg for your existing (plus weight of rope) so add bags of sand of 55kg in the anchor locker and see if you notice any difference in a rough sea. Why are you using 10mm chain? 8mm is perfectly adequate. 50m of 8mm chain will weigh not much more than your 25m of 10mm including the rope. 6mm high tensile chain will be strong enough.

This is barbotin. There is not 8mm for Leroy Somer as I think..

Amazing. Are you sure you have 8mm? Have never seen the info that exists for Leroy Somer. Do you have an info where could I buy it?

Hi,

Did anyone have a problem with a boat leaning suddenly to one side on higher speeds? It is pretty extreme leaning.
It happened 4 times.

First time:
- to starboard side
- calm sea
- 16-19 knots of speed
- leaning increased linearly over approximately 4 seconds period during linear speed increase after leaning increased rapidly following the speed increase (with small delay compared to speed)
- 5 men on board walking, didn't pay attention on weight distribution
- cause: I guess something speed has to do with it?

Second time:
- to port side
- calm sea
- 16 knots of speed
- leaning in one second when one man went from the middle to the port side disrupting the "ideal" weight distribution
- cause: disrupting the weight distribution? I guess 100 kg walking during higher speeds is not a small thing. What are your thoughts?

Third and fourth time:
- I would say starboard side, but due to sea conditions not sure if it was clean leaning to one side
- 3 to Beaufort scale
- 12-13 knots of speed
- I would say port side was more heavier a bit
- cause: ?

When stationary, the boat seems leveled.
Also, on the same day when last two occurrences have happened, it went from 15 to 22 knots on a calm sea (part of the bay protected from the wind) without any leaning.

My plan is to check:
- boat weight distribution while stationary (any suggestions how to measure it?)
- check for any water in the hull (but I don't think so)
- check the steering system (rudder bearings are new)
- check the propulsion system (new axle and axle bearing)
- any other suggestions?

Also, I will try to provoke leaning with different things to see what exactly is happening (on these occasions I wasn't expecting it so I didn't pay full attention)
I'm unexperienced at the sea (my first boat) so that may also be the reason. I have cable steering system which returns feedback to the wheel. Maybe my grip is not strong enough. Anyone with cable steering? How does it feel to drive it? Any good advices to share?

My propeller is right handed. Am I correct?
I assume it has some effect if it turns out the "problematic" leaning is always to the starboard side.
Can it be that extreme? What are your experiences?


Sorry for the long post and many questions. I'm not able at the moment to go to sea to test this, but it keeps occupying my mind

Hello, I don't have all the answers for you but here is my experience: at rest, my 760 is level if the fresh water tank is full but a small list (lean) to starboard if it is nearly empty. This is a 3 tonne boat so the position of people on board will make a difference. Above 16 knots there is a list to starboard that increases with speed . The amount of list at speed is dependent on the amount of fresh water and the position and number of people on board. However, although it may look strange, I have never experienced any real problem or adverse seakeeping from the list. I hardly ever cruise above 16 knots and never in rough water anyway so unless I can ask any people on board to move I just ignore the list. I do have trim-tabs so above 16 knots I can correct the list but this makes no noticeable difference to handling or speed improvement. I have had my Antares 760 for 10 years, cruised between the solent, the Norfolk Broads and the Netherlands and have been very impressed by it's sea keeping and I see no reason to worry about a small list at speed and if I did not have trim-tabs I could not justify the cost of fitting them for the benefit.

Plum, thank you on your answer! Hopefully this will be a result of my inexperience and not knowing the boat so good.

Btw, any suggestion which top to install on the stern? I prefer hard top over bimini, but I'm not sure how much it impacts driving at higher speeds.

Depends on whether you want a fully enclosed cockpit or just a sun awning. I only have a fabric sun awning for use when not under way. One that I have seen and admired, better than mine, is this one. No supports and the frame, when the fabric is removed, can be slid forward:-

 

[Forp]

I would like to have a fully enclosed cockpit so I plan to have the fixed one. But I don't know what are the downsides of the fixed one when driving a boat.

 

[tomaz_slo]

Mine is the original Leroy Somer winch and I have 8mm chain. I believe they fitted 10mm barbotin to some of the Beneteau sailing boats. Your barbotin is what i call a Gypsy

Plum, now I am a bit confused, because on one French forum I read that gypsy is 8/10 mm? Do you think is possible that one can take both 8 and 10 mm ?

In just my experience, no. Also, there are two sizes of 10mm chain and each needs a different gypsy. 10mm chain can be - DIN766 (10mm x 28mm links) and ISO4565 (10 x 30). I can't guarantee I am right though so hopefully others will reply too.

Well done on fitting the access hatches. How did you get to the bolts on the forward side of the tank, the ones that fix the tank to the hull?

Recently bought 2005 antares 760.
the bar connecting the back of the keel to the bottom of the rudder is badly corroded.
very expensive to buy replacement.

has anyone got any thoughts ?

How bad is it? What is the reduction in thickness? Assuming it is galvanised steel and only minimal reduction in thickness then remove, grit-blast and re galvanise. It should also have a zink anode too. If the corrosion has significantly reduced the material thickness then a local engineering/fabrication company will make you a copy from your old one and get it hot dip galvanised.


and below, this is what the skeg looks like when the metalwork is removed (different boat)

I changed mine two years ago and have the old one as a spare. It’s in a pretty good condition. If you want you can PM me.

Very interesting comments about the keel / skeg... I was literally thinking about looking into a replacement this week!
Mine has suffered a bit with corrosion and wasting in the marina (i do check and replace the anodes but the boat is 20yrs old).
Before it gets too bad I would like to replace.

Q1 - Does anyone know the rough price of either a new Beneteau one or getting one made locally?

Q2 - I managed to scrape a chunk out of the rubbing strip the other day at the bow - has anyone ever replaced the blue plastic strip?
It looks one piece all the way round unless I have not noticed a join...

Q1: From Beneteau dealer in 2022: 494,10€+VAT=602,81€
Q2: Original blue one was available in 2022 from Beneteau dealer for 8€+VAT/meter. 21 meters is needed according to Beneteau info.

Hi
Many thanks for the quick answer - I was hoping it wasn't going to be too expensive - 450E is still a lot for a bit of metal but that's a bit less than what I expected thankfully. At least it's not a Volvo part!

Thanks for the rubbing strip details too - that's also good to know.
Do you know if it's an easy job or hard work to fit? I was wondering if it is fixed one end with a locking screw then simply pressed in all the way round then fixed at the other...
Hopefully

Thanks

Hi, it is easy to fix. It’s soft. You start at one end and then go slowly around the boat and insert it. At the end you cut both ends and fix them with the cap.
And don’t forget to reseal all screws around the alu profile.
