Hunter 36 Punta Gorda
Flex O Fold

When I first got my 07 H-36 I would get A winning some thing noise from certain rpm's but after afew weeks of motoring it stopped .
I have a 3 blade Flex O fold and love it and recently had a few sailors race on my boat and not Hunter owner and were impressed how smooth my engine ran and very nice rudder steering.

I changed from a 2004 Hunter 33 to new e36 late last year. After sailing it for a number of times now, I am interested in opinions from the forum while I work with the dealer on these issues.

1. Main sail. I have a furling main with vertical battens. I find that with the main sheet pulled completely in, the leach is still not completely tight. Therefore I cannot completely get all the twist out of the main sail. It happens to be about the amount of twist I usually have but I thought that I should have the control range on the main sheet to pull the twist out if I really wanted to. At first I thought that the mast was rigged up with too much rake leaving less room for the boom to lower before touching the arch. However, the dealer said there is no rake for the mast and that we should look at having a sail maker come and trim the bottom of the sail off to give me the option of pulling the leach tight. I find it unusual that Hunter should have the size of the main sail wrong on a production boat. Any other e36 owners with this issue?

1. I would look to see if you have a Leach and Foot Lines to adjust. You should have these near the clew of the mainsail. If you don't the OEM sail you received should be sent back to the sailmaker to put in. I would also check the J, E and I measurements to see if the cut the sail right.

2. Variaprop. I have Variaprop (variable pitch propeller) on the boat and love the reduced drag when sailing. However, the helm starts to oscillate when engine rpm goes beyond 2000 and the helm wants to veer to starboard if I am not holding it down. My guess is that one of the blades in the prop is not balanced or pitching the same as the other two blades. Any other Variaprop owners with this issue?
I would make sure the engine is align to the prop shaft. If it is out of alignment you will get vibration. I would also check the cutlass bearing and strut to make sure they are aligned and installed properly. In addition, I would check the cutlass to make sure there is no play.
Sending the prop back to the manufacture to see if the blades are balanced is also a good idea.

3. Jib furler spool cover. This cover has a bad tendency to rotate with the spool when the spool gets close to full which results in the furling line wrapping around the cover instead of in the spool inside. I see that the line wants to wrap on the upper part of the spool so lowered the line guide before the spool but the same happens. Anyone out there with this issue and a fix? Anything wrong with forgetting about the covers?
Covered my others,, set screws. Also check the alignment from the last pulley to the drum to make the angle and horizontal entry into the drum is true for the line.

I have a special Harken doubleended mainsheet arrangement that led the mainsheet down on the two sides of the arch. It works great in that it does not interfere with the traveller movement as Hunter's standard arrangement would. Works good but I hardly ever adjust the mainsheet now that the twist that I want is always there.

I have the boomvang line come in over the coach roof on the clutch position where the mainsheet was on standard Hunters and that is great in controlling the boom when it swings outside the range of the traveller.

The vang also controls the top 1/3 of the sail when beating into the wind. Try tightening it a bit.

Oliver.
Hope this helps.

The whining noise at certain RPM is called a singing prop. Long and short of it is cavitation of the blade tips.

I have a 3 blade fixed pitch (15d 12p). I don't have any excessive vibration or remarkable pull.

As far as the boat wanting to turn while motoring, I believe that this is normal and due to "prop walk". Our 38 with Vari prop will turn to port in an increasingly tight circle if the helm is released while motoring. This is because the rotating prop is pulling the stern to starboard. In reverse the prop pulls the stern to port. We use this docking and turning the boat while manoevering. We do not get any significant vibration from the prop while motoring. Last boat was Niagara 35 with Volvo Sail Drive, it also would spin if helm was released while motoring.

Thanks guys.

I read somewhere that we have to deal with prop walk in reverse because propeller blades are designed to go straight in the forward mode which end up doubling prop walk when in reverse.

I did not have this "forward prop walk" in my previous boat (33 with fixed 3 blade). The dealer thinks it may have something to do with the distance between the prop and the rudder but I think he may just be guessing.

Will post more when I find out what Variprop in Germany have to say.

It's been three months plus since sending the Variprop to the factory to have it checked out.

Just got word that it is back and the factory said there is too much play on one of the plates (?) and two of the blades are slightly out of balance.

Supposed to be fixed and hopefully it explains the vibration issues I have had since getting the boat.

The yard is too busy to reinstall the prop over the next few weeks so it will be haul out next spring before I get to know whether it is all good.

Will see then.

I notice that most of the responses deal with your prop but little is being said about the most significant issue you are having, the inability to close the leach of the main. The dealers response about having no rake is a none answer. All masts have rake. Did he mean zero rake? Ideally you should have about 2% mast rake. But if you have a full hoist to the black band and you still have no way to close the leach then the sail was made incorrectly. A leach chord can be used to control leach flutter to some degree but will have little affect on a too deep main and will seriously degrade the exhaust coming off the sail.

The leech issue cleared up when I changed my routine in unfurling the main.


I was sailing with a deep draft and stopped unfurling the main when I had the deep draft that I wanted. The main was also somewhat loose and I could not stretch the leech as the clew was high.

I now unfurl the main completely by first pulling it all out until it is flat. Probably because of the much higher tension on the out haul when doing this, the clew came down much lower and closer to the boom allowing the leech to be stretch tight enough with the main sheet tight and boom at low position.

After that I let the main sheet out to get the twist I wanted and also to loosen the outhaul for deeper draft in lighter air.

For some reason that I do not understand, the clew stay a lot lower if I do this. It seems pulling hard on the outhaul lowers the clew and then it stays down even when I loosen the outhaul back.

I now have enough to stretch the leech straight enough given there is always some twist required to get all three levels of tell tails flowing.

Not much in reserve but enough.
