Still trying to fine tune bits for a new 33i, I am wanting to fit a rope cutter at the propellor does anyone have experience of the different types as there a big price difference between the disc and scissor types.
Also looking to get a bruce anchor for a 33i and was wondering if anyone using this type and if it stows on roller without touching the gel coat and what size anchor.

I have used both types. Current boat has the standard disk that Jeanneau fitted as an option. Touch wood not lines or problems in 7 seasons, and I like the simplicity. Previously I had an Ambassador, and whilst I did have wrap that it cut (quite thin line though) I never liked the way you have to drill the P bracket - this need to be done carefully, also I have worries that if it fails to cut a big rope or wire then it would exert massive forces onto the P bracket. I know quite a few people who don't fit anything and haven't had problems - if you wanted something for reassurance I would just go for the disk cutter.
Regarding anchors, Bruce ones seem to have dropped out of fashion on yachts - the new breed like the Manson and Rocnor have impressive feedback. Personally I have used a Delta on both my last boats and never had an issue - but then I do lay my anchor with care. That seems to fit well on the bow roller of my last boats, but can't speak about the 33i

Malcolm ,
The first thing I will do when going on the hard again , which will not be in the forseeable future , is to remove the disk shape rope cutter.
That ugly thing is worth nothing .
Remember my topic in the H&T section about the P-bracket ?
Well , the same thing happened again , be it that this time no serious damage was done inside the hull.
What we need is a good and recent study/test of all the available rope cutters , the sea and shorelines are full of boobytraps.
Regards

Sailbleu,
sorry to hear of you having another wrap around your P bracket, it is a dilemma wrt which rope cutter as after a bit of reading up they all got their down sides. My dealer forwarded me a link to a boat magazines video and tests on the various types, the disc type faired well however I read an article from a observer who was at that test and he was a bit critical and stated that the ropes/ nets etc were secured to the tank in front of the cutter arrangement in effect holding the ropes etc for the cutters to work so not exactly realistic, I noticed also in your HT article your disc had the grooved type blade this I had read actually grabs the rope and encourages it to wrap around the shaft. I have also read as Malcolm mentioned the other scissor types if they do not cut the obstruction can also transfer loads onto the P Brackets which apparently are not so heavily constructed these days.
Im thinking of just getting a smooth disc to start off with as do not want to have nothing and hopefully a more up to date test is done or hearing other feedback before attaching anything to the P bracket. Thanks for sharing your views.

Here's what we have on Affinity. Unfortunately we've cut through 12mm Dyneema and a woven 1 tonne bag. So we know this works and no problems with P bracket or gearbox. We did have to clear the prop shaft each time which meant coming out of the water, hence going to complete the RYA 3m dive course in the spring.  |

Cheers for the photo Ian it looks pretty purposeful and by the sounds of things similar to Sailbleu has, so hearing the good and the bad, at the moment after chatting with supplier of the quickutter rope cutter looking at that although it not such a straight forward fitting as one part has to be shaved to match the diameter of the propellor hub. The RYA diving course sounds well worth it though for a last resort with a bread knife.

I have exactly the same rope cutter be it that mine is further away from the P-bracket .
Dont know if Ian's setup is better , atleast no rope can get in between the cutter and strut and cause devastatingeffects.
But something will have to be done in my case , I've read stories of brackets that where broken off . Sofar we're spared from this kind of an ordeal , but you can only tempt faith so many times.
I do wonder though , if and when the cutter is installed that close to the strut , will there be enough water lubrication for the cutlass bearing ?
Regards
EDIT:
about the diving issue , a small advise.
As a fanatic diverfor many years I have the neccesairy gear on board of course .
In the past I had to go down several times to clear the prop(shaft) , tighten zincs, and so on. Each time it's a serious procedure to get all the equipment on .
This year I have decided to buy a 5 to 6 meter long second stage hose so the scubatank and buoyancy jacket can stay on board.
Saves you alot of hassle .

Anybody got thoughts on the micro scuba kit?

Post by MalcolmP on Oct 26, 2014 8:43:12 GMT
This is the type I had previously - you have to drill and tap the P bracket to fit the fixed striker plate www.ropestripper.com/glossary.php#fixedVery expensive and have mixed reports and those bearings wear quite fast |

Post by sailbleu on Oct 26, 2014 9:14:04 GMT
Not sure if I understand why these bearings are needed ? The rotating blades are fixed to the shaft no ? Why not make it like the disk rope cutter ? Man , if my boat would on the hard for the winter this would be for sure my next project. The H&T he Malcolm  Regards |

Ian, we use a delta anchor on Affinity which has worked well for us. I just checked out And I see there are a number of used CQR anchors there about £25 each and around the 10kg you need. Just a thought, Ian |

Cheers Ian worth a look as all the extras are soon mounting up. Priority at the mo to get me started is a rope cutter either the disc or quickutter an anchor either a Delta or Kobra 2 see which fits the roller best and a radar reflector and anything else I need to get on the mast before it shipped as don't fancy going up there later on.
Wrt micro sub aqua gear the offshore industry now have mini underwater breathing apparatus supplied to workers going off shore in helicopters to assist in underwater escape.

Ian,
On my SO32, I had a 16Kg Delta anchor, which was one size up from the sizing table that Lewmar publish. This just fitted my bow roller, and never dragged in the time that I had the boat. For the 379 I decided to try one of the new generation spade type anchors and chose a Manson Supreme from Force 4 in Swansea. They let me borrow their stock anchor to try on the bow roller to ensure it would fit. I'm sure that Nial in Force 4 would allow you to do the same. I think you will find that the modern Jeanneaus have quite a good overhang on the bow roller, allowing a lot of anchors to fit OK without touching the stem.
As far as rope cutters are concerned, we had an Ambassodor Stripper on the SO32 that on more than one occasion worked for its living, including catching a line going across Carmarthen Bay to Tenby. As a result, we fitted a Stripper to the 379, although we now have a sail drive rather than a shaft and P bracket. If anything, the sail drive was an easier fit, although we needed to specify that we were fitting a stripper when we ordered the Kiwi prop for the boat, as it needed a slight mod to the hub.

Cheers Jon I am leaning towards a 16kg anchor and will see what force 4 have in stock when boat arrives in January I had a Bugel type anchor on my previous boat and must admit it was excellent so should think the Manson will preform really well around our coast, also lots of pots around here and I have seen quiet a few lurking just below surface, a local fisherman mentioned to me they are putting short ropes on then to pick up at low water and to limit others from interfering with them which is annoying to say the least so hence concentrating a bit on the rope cutter.
I was wondering if you have put a third reef in your mainsail (unless it furling) I think its something I may look into once I got a bit of sea time in on the boat as the local sailing school seem to be out in all weathers in their Jeanneau fleet (I think they have a 379 now as well) and look very comfortable with a third reef in. Nearly there now with planning the extras roll on January.

Have a Manson supreme, works as advertised easy to set and fits on roller no problem, but I take great care in raising last few meters as it is v close to gel coat, haven't got a rope cutter as I have a flexfold prop and only way to fit a rope cutter on a SD60 saildrive involves removal of metal which I have decided not to do. My classic main came with 3 reefs installed, 1 and 2 single line and reef 3 needs hooking on at gooseneck (on a DS50) with all the assy spinnaker gear and releasable forestay and extra halyards does make it busy around cabin winches.
Regards
Ab

I would also plan to have 2 vhf cables and tv cable installed in mast on commissioning, cable is cheap as chips but installing later is a nightmare. Supply your own cables of suitable spec from radio ham type shop rather than the cheap thin stuff that comes with a vhf antenna, if you are supplying a radar test the cable before installation, luckily I did and managed to get a replacement before instalation in mast.
Not sure if you are copper coating but if not ask exactly how many layer of what primer and paint will be used, I'm 6 months in the water and primer is showing at waterline, so I doubt the manufactures spec on number of coats was followed.
Any case watch everything and photograph it, and before commissioning if the yard says it doesn't like you to hang around and watch, make sure you do,
Caveat emptor.
Still, love my boat just a pity jeanneau won't finish building it, sorry I mean repair the defects!
Ab

Thanks for your feed back abgreenback, good advice, Im not sure how many if any spare sheaves in the boom for reefing. One thought was to see if the second reef block on the sail was moveable and if a third reef needed shift the block on the sail up and re reeve the line at the booms end. Its difficult without seeing what the arrangement is. Im still not 100% on the copper coat as it does not appear to be as effective here in Neyland which has a lot of fresh water in the Marinas upper basin Im thinking of an epoxy coat on the hull with regular anti foul. But IF copper coat does what it says on the tin then could be persuaded. Jeanneau in Swansea are saying they apply 5 coats of copper coat. I hope you boat gets finished soon .....

Wrt micro sub aqua gear the offshore industry now have mini underwater breathing apparatus supplied to workers going off shore in helicopters to assist in underwater escape. if you mean this www.spareair.com/Don't bother , I have one on board and don't use it because there's never enough air to last the job . Besides , this thing is dangling in your month making it not very comfortable to free the prop or replace zincs and all. Again , a 3 mm suit (overall) with a hood . The hood is neccesairy during the winter or in colder climates , not having one on the suit will make you come out of the water with a headache for sure . A well trimed weight belt , a pair of small/short flippers , goggles and a regulator attachted to a 6 meter hose running all the way to the deck . It supprises me every time I read or hear stories of boaters having to call in a diver to free the prop and things like that. The costs of calling in a professional diver 1 time almost equals the collective price of the gear mentioned above. It's best to take a short training to get familiar with diving as such , but since most of you will not be diving deeper than the keel you could also train or learn on your own. |

I have just been looking at some photos I took in the commissioning yard and it's quite revealing. 0800 boat on delivery trailer, 1229 boat still shrink wrapped, 1339 first coat of interprotect nearly finished, 1505 2 coats (?) unipro applied and all masking removed!!!!
surprise surprise 6 months later grey primer is showing through, man from international paints said should be easy to sort out as none of the curing times have been followed it should come off easy with a pressure wash.
Still less than 3 hours to prep , prime and anti foul a new 50 ft yacht is impressive.
as I said caveat emptor!!!

Cheers Ab, useful to know. Hopefully as dealer fairly local I will be able to keep an eye on things but its handy to know the various issues to look for.
