[Mango Cat]

Hello to the thread, and apologies if I am not posting this in the right spot.

I just had a new 120% Genoa built for my 1989 P39.
Unfortunately they did not triple stitch the seams as requested, and as indicated on my order confirmation letter.
They acknowledge the mistake, but the question is what to do about it. It seems to me that just adding another row of stitches over the two rows is not a good solution. The two rows are wide stitches that use all the area of the seam. Adding another overlapping row is the sort of thing I would do to get a little more life out of an old sail, but I hate the idea of doing that to a brand new one. Any sailmakers out there care to comment?
How much durability am I losing if I accept this one as is?
Can I really reject the sail over that kind of construction detail?
If anyone wants a 9 oz 425 sq ft jib with blue sun cover and a luff tape for Profurl, there may be a surplus one available.

I believe the French manufacturer of these bearings is JP3 Steering Systems:-
Tel.: +33 (0)5 46351078
Fax: +33 (0)5 46351093
info@jp3steering.com
www.jp3steering.com
The web site does not work, but the US importers website does.
The bearings are JP3 Rudder bearings Type 1

The rudder bearings are made with an Ertalyte knuckle bored to the diameter of the rudder shaft and seated in
an aluminum body.

A pdf file illustration the bearings is here

I have a 2002, Sud Composites Switch 51, Hull #6, with the same bearings and the same problems. I will be dropping a rudder later this week in the Rio Dulce, Guatemala, to ease up the movement on my starboard rudder, port rudder is perfect. The US importer claims the problem is due to insufficient clearance between the shaft and the bearing. They have been complaining to the French manufacturers for a number of years. Maybe the manufacturer has shut up shop.
Dufour 32's also use this type of bearing and there are descriptions of the same problems here.

The material is Ertalyte® TX
"Ertalyte® TX for machining high-wear-resistant parts is an unreinforced semi-crystalline thermoplastic polyester (PET-P) that has a solid lubricant filler. The material has excellent performance in both high-pressure and high-velocity conditions, and is ideally suited for applications involving soft metal and plastic mating surfaces.

Key properties of Ertalyte TX, are its high strength and stiffness, high wear-resistance, very good dimensional stability, high creep resistance and very good chemical resistance. This combination of properties make it an ideal material for machining bushings and bearings that require no startup or running lubrication. Ertalyte TX has FDA and USDA compliance and is ideal for applications in food packaging and processing equipment. Ertalyte TX shapes offer dimensional stability, wear resistance, and low-friction characteristics superior to those properties of competitive filled polyethylene terephthalate polymers. Excellent replacement for Delrin AF. "

But I guess Delrin will do! Unlike Nylon, Delrin should not swell with age or water, that's been proven over many years. Maybe Ertalytehas not been proven.

I'll be dropping a rudder later this week, using a Hookah, to free up a lower bearing. Thanks for all the advice in the message board.
I believe that the problem could be expansion of the housing do to corrosion, putting pressure on the bearing forcing it against the shaft.
I'll know more when I see my bearing later in the week.

Switch 51, "Zia".
Rio Dulce, Guatemala.

[Peter Verralls]

The starboard rudder on Zia was removed to ease the lower self aligning bearing.
The bearing is manufactured by JP3 Steering Systems in France. Their web site is down, but their US importer has pdf files and specs on the bearings.
http://www.lminewport.com/pdfs-2009/...1_bearings.pdf
It appears that the aluminium housing corrodes and the expansion cased by the corrosion deposits force the Delrin bearing into the shaft, making movement difficult. The housing is glassed into the hull, so the short term fix is to enlarge the bearing a little. The shaft is 54mm diameter on the Switch 51. Upper and lower bearings are the same.

This is a thread that has not been highlighted for a while.

I have a privilege 37, and have a liferaft mounted on the coachroof between the mast and the front of the bimini.

Quite a good position for weight distribution, Not so good for deployment, and a real pain in the @@rse for forward visibility in the cockpit.

Where do other Privilege 37 owners keep their liferafts?



.

[privileged]

my P37 has a stainless steel bracket with two timber steps on it on the rear of the cockpit transom and the raft is strapped on the bottom step . It all apears to be original from the factory.

Here is a pic with the raft removed ,the bottom step is about 400mm wide and the raft fits in between them

I think my P42 had the same or similar setup as Privileged's P37. All that was present when we bought the boat as the upper brackets and filled holes for the lower brackets (circled in attached photo).

The photo below shows why I cannt go that route.



The passarelle stowage would get in the way. This also provides a stowage for a wooden plank for use on piles.

This leaves the question of where to stow the liferaft! I really do not like it obstructing the view forwards from the cockpit. It makes berthing starboard side to a bit of a bother! Do you have a liferaft?

We don't need no stinkin life raft!

My mount's are in the same location as Daydreamers. I'd guess the solution is not to carry your dingy so high. I'll have to inspect this area in a more detailed fashion when I am down on the boat this weekend.

You could however device mounts in combination with the stantions in the aft part of the boat. That would keep it from interferring with the dinghy, make it readily accessible and easily deployable.
