    Posted: 15 October 2002 at 8:47pm

On my boat there is a pad eye bolted into the deck near the outboard rail in line with each primary winch.  I lead both my genoa sheet and jib sheet through a block attached to the padeye to the winch.  It seems the lead is too low and tends to override unless you tail the sheet upward  while tacking or rounding marks. 

Was this padeye intended for use as a jib/genoa fairlead?  It looks like the genoa sheet could be lead directly from the genoa car (on the lower deck) to the winch, but I never tried it.

If you have a padeye there it is because it was added by someone. Originaly the boats had the Jib/Genoa turning block attached to the aft stanchion base.

I recall on our boat while we were using this system and sailing in Kingston in about 25 knots of wind when the stanchion base decided that was too much and let go. The block hit a compass we had mounted on the cabin bulkhead and shatterred it while sending the oil everywhere. The velocity with which that block went flying was scary.

Anyway, to shorten a story that's now getting long in the tooth, we no longer use any turning blocks. For the Genoa the sheet comes straight back from the car on the lower track. For the Lapper, the sheets get lead to the Genoa car which acts as a kind of fairlead as you cannot sheet directly from the Lapper track to the primary winches.

Hope that helps Dave,

Dave,

Interested to here that you have done away with the primary turning blocks. Do you every have a problem with overides? What are the rest of the one design guys doing?

We found that the original stanchion bases where not up to the task as well. I have replaced them with the newer (much more robust) bases from Bill Layton.

Re Winch overrides

I seem to recall that most winch makers suggest a line entry angle  of 90 to 75 degrees. Meaning the line would be 90 degrees to the drum or upto 15 degrees less than that. All this to say that its best if the line comes upto the winch at an angle thats not greater than 15 degrees. As Paul mentioned, the sheet from the lower genoa track directly to the winch is fine.  So is your pad eye.

However one interesting thought comes to mind: One year we had a new guy doing the genoa for us and he kept getting overrides. This problem was intermittent until we noticed him wrapping the winch backwards......problem solved.  Wrapping the winch backwards always gives you an override!

Glad you like your stanchion bases Chris.

On Hyder Ally, we have broken off the stantion base attachment for the turning blocks, both Port and Starboard. I added a cheek block to the cabin side at the aft end, which gives a very nice lead. As long as I'm breaking class rules, I'll say that we've had great success in adding an inhauler for the Genoa leads. The standard location on the cabin top is too far inboard for our long spreaders. The sail looks overly twisted. I installed the deck, outboard tracks a bit further outboard than usual and now have a block floating on the genoa sheet that leads to the cabintop lead. Aft of that is 3:1 purchase lead aft to the aft cabin face, turning 90 degrees to a cleat on the bulkhead. The tail is lead across the boat and can be easily played like a barber hauler, easing the jib lead outboard when the traveller is dropped. The best lead position seems to be about mid window - just where you could never place a track. The block never flails around and playing it gives the crew something to do upwind. On reaches the outboard lead works great with no need for an outboard barber haul. Genoa sheet tension is little affected by the inhauling as the pull is nearly perpendicular. It also gives you a "pinch mode" when necessary, by inhauling all the way in to the cabin top track. My impression is that the boat goes better with the less twisted jib, sheeted a little outboard, but with few other Laser 28's around on the Chesapeake it's hard to tell! Regards, Tom Price

How far from the toe rail is your genoa track?  I doubt this breaks any class rule.  Barber haulers (outward) were part of the original design.  Most of our (Montreal) boats removed them because they were not found to be helpful after moving genoa tracks off the cabin top on to the side deck.  We would normally be changing foresail to lapper before the wind gets strong enough to need a wider slot.  The genoa is not useful at over 12 knots TWS especially if you have invested in a newer (larger) lapper.  Another factor is that we race almost exclusively on windward / leward courses with no reaches unles the RC has made a big mistake!

Andrew,

Interesting that in One Design you would rarely carry the genoa above 12 TWS. If we are carring lots of weight (1100lbs+) and especially in a bad chop we will carry a heavy #1 (not a class All Purpose Genny) upto 16 or so. I do agree that the lapper is the right choice under many circumstances and certainly in flatter water.

We rarely use the cabin top tracks now that we installed deck tracks. Have the one design boats removed them?

Waves are the key issue on whether to use the genoa at over 12 knots. In flattish water there is no reason not to change to the lapper...in a big sea it can be a different story.

I have sailed with Ian Bruce in the mouth of the St. Lawrence river with 10 to 14 foot waves and winds of 18 to 24 knots...we sailed with 2 reefs in the main and the genoa sheeted with the barberhauler. In that case we needed the power to climb the waves.

All that said though, negotiating roller type waves is easier than steep chop in confused seas.

Just my $0.02...cheers,

Scott mentioned a new larger lapper.  Could someone explain this to me.  Is this a class sail (106%) or something else?

Hi John,

Well it's design is a few years old but much bigger than the original that came with the boat. 106% refers to the LP which it still has. However, the roach is much larger. So large that it can touch the front of the spreader when sheeted in all the way.

The story is: When the class updated its rules in 1997 we opted to go back to the original size Lapper Bruce Farr had recommended. The reason all the original Lappers were smaller was because the boat was supplied with a genoa which was never the intention. Bruce Farr designed the boat without genoas just like the Mumm 30 etc. We supplied them with genoas because in order to build one-design fleets we had to get good exposure in PHRF fleets first. Once one-design fleets were established owners still wanted a genoa so they could still race PHRF more effectively. So with a genoa we thought the Lapper could be downsized a little and thats the way it all started.

We sell new Lappers for $1558. canadian + shipping. Hope this helps.

Bill Layton, Quantum Sails

No, the tracks are still there just not doing anything.
