Hi all 
I've been given a unused Holt Main sheet swivel ( part number HA-4266 ) which I want to use on my old National Solo (1972) as the old (and probably) original is pretty much worn out and wobbly....

So I ask 'does it matter that my 'new' block is missing the small internal swivel stops and would rotate 360' ?

I've asked a fellow solo sailor and others down t' club...
... and we are not to sure, by the way, offering up the new part shows me that there is no issues with obstruction with the traveller car or anything else .

Thanks to anyone in advance for taking the time to answer.

ps I've looked to buy the missing parts online  and it doesnt look like they are available.

I would say it will be fine, it will only pivot when you pull the fall and as you don't ever go in front of the traveller you'll never pull it in that direction.

Depends on you really. If you never let go of the mainsheet, always keep it taut and never capsize then you'll probably not even notice. But if you drop the sheet or capsize, and the sheet winds round the tower a time or three it can vary from mildly irritating to damn dangerous. Ought not to be beyond the wit of man to organise some sort of stop if you don't mind it being limited to about 270 degrees.

The tower on the Spice only rotates around 200 and it's bloody annoying in the light......

If your "old and wobbly" mainsheet swivel is a Harken, you can buy replacement ball bearings and recondition it fairly cheaply.
Do check the fixings to the centreboard cap. My Solo had the standard 4 wood screws - these protrude below the mount and seem inelegant and difficult to tighten once the wood has suffered.
I replaced the screws with s/s bolts, washers and unlock nuts.

I would have said there were a few other things that cause annoyance when sailing a Spice in light winds than the main jammer not rotating. LOL

The Blaze is fairly kindly to 'knees' in fact... all you need frankly is a pair of foam based Volleyball knee pads anyway... Most are far better than 'dinghy' pads ... and massively less expensive.
