My boats have had mostly Holt blocks - 0 breakages in 7 years. Of course that's probably because they are not loaded above their rating, and the fittings that are highly loaded (jib cascade or top kicker block) were the wire version and designed to carry the load. Fittings can receive severe shocks in gusts and waves especially in high performance boats.

The spinnaker halyard block really ought to be a wire block i would have thought for an assymetric kite that would get around the saw problem.

I'm not a fan of the Holt alanite cleats, though the metal ones are better. I actually prefer the RWO servo 11 if the control doesn't warrant the super £ching Harkens.

As an aside has anyone else tried the Clamcleats with cages? I've got some on my boat and they are fantastic (Spinnaker halyard, and pole vangs).

Having  hammered through  harken ronstan and holt ball bearing blocks on the 14 the biggest lesson  I learnt is to go for the best  block for  the job ie  harken or ronstan high load blocks on the kite halyard  rather than the standard ball bearing blocks and check it reguarly. Rachets   holt are okay if  they work but i have heard to many problems  of them not working   but when one failed on my wife's new  200   i  just told the dealer and got a replacement next day  no quibbles. For high load wire or  dyneema  (shrouds  or jib halyards) holt or proctor wire blocks were definetly  the only  blocks I used.

as for why smods  use holt it  was normally due to them being cheaper  and  at least supporting   some british industry. 

For the orginal  question  which was for a  phantom  my recomandation  is  for the main sheet  harken carbo  blocks and ronstan rachet. kicker  block at boom holt wire block   rest of system harken 16mm air blocks. Out haul and cunningham, harken airs as them are the lightest.  adjustable shrouds  holt or proctor. Cleats harken or spinlock depending on   set up of your controls

The  best   thing is to go to a class open meeting and look at the top boats and speak to  the sailors  to see if they  have made any mods  to the standard option and ask  for that.

p.s  due to the weak dollar  at one stage rs were  willing to do a harken fit out  for the same price

for ratchets, I'd go fredreiksen - purely on pose value, you understand...!

Otherwise, It's all about how you look after them.

Reckon that it's all much of a muchness - believe that volumes and types of sand and salt water probably have much more impact on life of the pulley.

Spinnaker halyard blocks on high performance boats have a hard life, they have to cope with running fast on the hoists and drops, some times under high load when things get stuck.
Then there is the shock loads when the kite flogs not to mention doing this full of mud and sand after you have stuck the mast in the mud.

some seem to cope much better than others.

On sheet loads if you cut the weight of the boat you cut the loads(keeping sail area the same)

Some very good points but it seems to me the most sensible cause of  blocks spontaneously "exploding" is that ropes with high loads like spinnaker haliards and the like make very effective saws and will quite happily saw through plastic. I'm sure once your rope sawsthrough you block it would give the impression of exploding because everything, such as bearings etc, would fall out .

I watched it the other night and noticed it, somewhere near the beginning I think where they are introducing the team

Something I have noticed as general trend in this thread, and it may just be me, is that when people say that blocks fail they are referring to their use on high performance boats. 

 

I would have thought that given these types of boats have been around for some years now that manufacturers would have solved the issues around the high loads prevelant and block failure.

There's no doubt that fittings do vary in quality but I would never say one supplier is better than another. I might say supplier one's XXX is better than supplier two's , but supplier two's YYY may well be better than supplier one's.

Its also fair to say that some jobs seem to exceed what most suppliers kit can cope with. I used to find that Cherub masthead kite halyard blocks were very short lived and I slaughtered some Harkens in that application. I can't remember what the best option was now, but frequent replacement was wise. The suppliers would probably spec some enormous solid thing to take the loads and speed, but who would want that at the masthead?

I have good evidence that the old Holt black and white blocks were shorter lived than Harkens in moderate load conditions, and at half the price that was fair enough.
The latest Holt blocks are an entirely different design and look pretty good: it would be foolish to assume that the same applies.

I have a feeling that blocks are all part of the "my boat is better than yours and I have more money than you" type argument.  Holt blocks work and aren't crap.  All this "my holt block exploded before I even took it out the packet" and "I sail my boat so hard I always break stuff" is just ridiculous.  It is against the law to state that products do something that they do not and products must be "fit for purpose".  Holt cannot sell stuff that is claimed to be better than it is so it is extremely unlikely that they do so.  If my blocks kept on breaking, I would start looking at other parts of the boat (ie myself) as the reason why. 

If you have a case, read s.14 Sale of Goods Act 1979.  

For a Solution, Holt blocks will do you fine.  Low loads and minimal line speed means you will not notice the difference between Harken and Holt.
