Hi,

Anyone who has fitted a Easy Matic (I or II) main sheet system on their boat? I'm looking for a way to improve the main sheet, because it requires me to much power to take it in.

Hello Gregor,

I have a Easy-matic system connected to a Lewmar rail on my 315 , works perfect.

Gregor,

I have a 30 m sheet but I would think 25 m would be enough

Thanks Claes.

Been looking in various shops for the Easy matic 2 (6:1). The lower block is out of stock till September :(

Yes, I tried them, they are nearly double the price of Technautic f.i. I got a quote from the local marine store for 240,- (if available....)

Just dropped svb an email to see what they can/will do.

You do not need to purchase such an expensive unit. Although it is probably nice to use
You can use your existing mainsheet block as long as it has a fiddle on the top.
You just add a small ( Say 10 mm rope size) single sheave block with a jammer & its own fiddle on to the fiddle of your existing block. You take the dead end of the mainsheet off the fiddle & attach a 10 mm block to it. Then you take a new line ( different colour & only 10 mm diam)from the fiddle on the new jammer up through the block on the dead end of the old mainsheet & back down through the new jammer. This line need not be very long as you only need the extra power when close hauled so enough length ( say 3 M ) to give you about a metre of extra adjustment on the mainsheet.
When you are close hauled & want to trim the main you pull in your old main until nearly in & getting loaded up then  haul on the new rope . this gives double the original purchase you had before.
If you do not like it .it does not cost a lot & you can blow all your hard earned savings on the posh kit later. You possibly have the spare bits on board the boat.
It is a good idea to have the adjusting line a totally different colour so you know which is which. the picture you show above does not have this & you can easily end up pulling the wrong rope.
to stop the extra jammer block from constantly dropping over the mainsheet block you can place a spring or a piece of hose over the junction between the 2. You just need to use a bit of ingenuity here to suit yourself.
Finally you do not actually need to fix the extra block to the top of the existing mainsheet block so long as you have a position in the centre of the boat where you can attach it. Ie on on the cockpit floor. Here it is out of the way but you can pull upwards on the line when you want to. Do not have a long line as you only need about 1 M of movement on the end of the mainsheet as once you get used to it you will know how far to pull in the mainsheet before you need to use it.

@Daydream believer: did you do this by head??? Thanks for the tip.
Do you have a picture available to make it clear, I'm not sure I quit understand the connection of the second block.

Hi
 
Follow this link; http://mauriprosailing.com/Merchant2/merchant.mvc?Screen=CTGY&Store_Code=MPS&Category_Code=HARMAINSYS3A - http://mauriprosailing.com/Merchant2/merchant.mvc?Screen=CTGY&Store_Code=MPS&Category_Code=HARMAINSYS3A
 
There you will find the main sheet system i use. A quick 4:1 for bigger adjustments and 16:1 for fine tuning. Works great for me!

Tricky has it correct except that for a 315 a single block on the dead end of the mainsheet is all you need to get 2:1 which doubles the existing 4:1   that 315's usually have  up to 8:1
If you can fit the extra jammer on the deck  clear of the main tackle then you can pull upwards & it does not get in the way of the gear when you gybe etc
If you do not have any spare blocks use your vang tackle as a spare just to play with for a quick test. However I think 2:1 is ample & too much rope gets in the way which is a recipe for a tangle at the optimum moment

Thanks for the info so far!

I don't have a spare violin block aboard, all are in use I understand this sure would improve the final trimming!

What keeps crossing my mind with this system, while sailing in stronger winds, it would still require me the same force to pull in the main as it is right now. That is what I would like to improve.

@daydream believer: do you have a picture available to show how it is done at the 315? I try to imagine how it would look and I'm not sure if I get the picture.

Sorry no pics but the link posted by Tricky shows the details
the only difference I would make is a 2:1 tackle on the dead end of the sheet & if you have a track but still have the standard mainsheet deadeye on the cockpit floor I would fit the extra block to that so you do not have too much gear sliding along the track
It would allow a bit longer adjustment on the dead end & would not affect track operation
i am suprised you want more adjustment on the mainsheet for pulling in as the easymatic does not do that ( at least I do not think so) It is designed to be used as normal low power for general operation with the extra power for final adjustment which is exactly what the system Tricky & I have described does. I do not believe that the easi matic is worth the extra cost. In fact if you can fit the extra block onto the cockpit floor the system is better than the easi matic
 
Any way-- To change the subject I am off on 2 weeks hols tonight --- Yippee!!!
First to Ostend then into Dutch waters up to Whillemstad & back to Ostend
Hope to catch a couple of the bands in Ostend & if its rough the wife will probably do what she has done before - Offer her services on the N S Y C committee boat for the Belgian Dragon championships
I do not understand why but if it is rough she will go nowhere with me but quite happy to sit in a committee launch in F 7 for a couple of days

Funny my wife will do the same, she has been known to sit in a committee boat for hours in similar weather for dinghy competitions.

To see if I get the picture.

First I have no traveller. At the bottom one violin block and at the boom one block. In total a 4:1 system. My question is, what do I need to change to use less power for pulling in the main especially when sailing close to the wind. The thought was/is Easy matic 4:1 / 8:1.

By adding one block the the end of the main sheet, I would reduce the power needed to pull in the main. I'm trying to figure out the flow of the sheet through the blocks by drawing it, because I'm not on the boat. For every draw I make, I keep missing one block. So I probably overlook something, but waht??

The link Tricky sent has to do with fine adjustment, and although something to think of, it does not solve my question. F.i. in case of stronger winds, I think, it would still require the same force as it would without Tricky's improvement.

Gregor

p.s.
Have a great holliday!

Hi Gregor
 
The system i use will give a 4:1 purchase for fast adjustment and 16:1 purchase on the fine adjustment. This means you only need to pull with a 1/4 of the force on the 16:1 rope in order to get the same force downwards on the boom. If you pull with 1kg in the 4:1 you need only pull with 0.25kg on the 16:1 to get the same downwards force on the boom.

Thanks for the pictures! It's clear how you've improved the reduction on the sheet. What is your sheet handling when gybing?

These are the blocks I have.





I tried an extra block as suggested inthe post of Daydream Believer and noticed that the force to pull in the sheet got more. This maybe has to do with the fact that the blocks are over 6 years old. I used wd40 on the blocks to improve rolling. Did not help much.

Hi
 
I only use the 16:1 when going uppwind. Its for really tightning the sheet and fine tune. When gybing i only use the 4:1 main rope. Remember not to let the 16:1 purchase get to "long" or the top block of it will stop in the main block and the purchase is reduced to 3:1Wink

there is no way that you need more force with my suggested arrangement as the extra block is on TAIL of the mainsheet & does nothing when the sheet is pulled in as normal.
You may have miss assembled the system
You do not need any more than 4:1 when pulling in the sheet from,say, a reach or a run, you only use the extra purchse once you have the boom " near enough" then you trim with the extra purchase.
If your blocks are worn then you have no hope. WD 40 is not advised for blocks - only freshwater rinsing.
I had a problem with my mainsheet jamming block & when i changed it I noticed that the block on the boom was distorted. They were Lewmar & I changed to Barton delrin bearing blocks ( mainly due to price against overpriced Harken  blocks) & that improved the situation a lot .
I suggest you think carefully about too many sheaaves in the tackle as you need such a long length of mainsheet & will get into tangles. It also makes gybing in a strong wind difficult as you cannot get the boom in quick enough & let it go in a controlled manner.
Too big a block on the mainsheet car will stop it standing up correctly ( even with a spring) & it will bear on the jammers & bend something.
I assume you have a track & that the pad eye for a non tracked sheeting arrangement is still in place. ( if not it is easy to fit one ) Your extra jamming block goes on the pad eye & the TAIL of the mainsheet has a single ( preff delrin bearing) block. You undo the fixed of the mainsheet & fit a single sheeve block. You take a sheet from the jamming block on the pad eye up through the block & back down the jammer.( you can increase this purchase latter but it is not needed) This sheet needs to be a different colour from the mainsheet & only needs to be about 6 metres long. Some boats use a smaller diameter sheet as with the extra purchase you do not need a thick sheet.
Your normal mainsheet works as it always has except that the tail is fixed to a the extra tackle. You can still slide the main sheet up & down the traveller.
