    Hello

    I have now decided to convert my boat to centre main , i know what thye setup should look like and how to do it etc. But i have a few questions on what hardwear i should buy on a budget . As my boat will not be raced or long distance cruised i have ecided that lovely harken gear would be wasted on me and would break an already broken bank , so could som one please advise me on what tyoe of block do i need eg size and if plain bearing will be ok , also could any one advise a buget ratchet block ? Thanks

    Sure, I used to have one exactly like that. And because it utterly failed on me while sailing the Kattegat, I never ever want to have anything from Barton on my boat again.

    LOL

    Really keen racers don’t use a cleat, they want to feel the pull of the sail at all times. A swivel cleat would only be expensive ballast and for that reason top racers tend to use a ratchet block only. At the very least use blocks with ball bearings so the friction is minimized and the “feel” is optimized. Without a cleat consider using a (auto) ratchet block if you intend to sail in strong winds. A ratchet block takes some of the load off your hands. The ratchet in a normal ratchet block has to be switched on or off by hand, an auto ratchet block kicks in automatically above a factory preset load.

    If you are on a tight budget, why not visit some of the countless boat jumbles that are held this time of the year? AFAIK almost every club has one.

    Another view from a racer,
    I like and use a mainsheet swivel jammer with cleat and also a on/off ratchet block ?

    Why? Well a cleat is very usefull to put the main in when I pull up the spinaker as i use two hands to help the crew and hoist so no way do i let the main out to do nothing.

    The on / off type ratchet is the only one I use on the main and the genoa sheets.
    I have had two types of auto,s and both failed on me and did not last too long for the money, so on/off for me only.
    Also in light winds the ratchet when on not only holds the sheets when i dont want them too but that clicking drives me mader than a box of frogs,so i turn that noise off till we need the help!

    Ebay sometimes has Harken gear forsale !

    True words Collin and don’t forget that a jammer also allows us to open a beer can occasionally 😆

    Thanks for your help guys ,
    I think i will opt for the on/off ratchet with no jammer , also could you suggest a size for the blocks on the boom ? would 45mm be the right sort of size ?

    You could go down to a 26mm as long as your mainsheet rope runs freely in it?
    prob a 8mm rope is the biggest for that block.

    If you check the manufacturers website they will give maximum rope diametre for the sheave size;
    e.g. Harken Hexaratchets 57mm sheave gives max rope 10mm
    That’s a maximum rope diametre, personally I find these blocks perform well on dia 8mm rope.

    Just one more quick question , what swl should i need for the blocks on the boom and the final block on the swivel base ? 200kg ?

    200kg is plenty.
