Pit/control line optimzation

-
As we race a lot of windward/leeward races, the efficiency of the pit is of primary importance. While generally well thought out in the original design and hardware assortment, there was a number of things I wanted to do to make it better. And as we often sail with asyms, it needs to support that as well. Some of the goals were:

Double end key controls (vang, foreguy) so they can be played from either side
Increase the purchase for key controls (vang, foreguy, outhaul, cunningham)
Run halyards for optimal port windward roundings
Create the same pit environment as the First 36.7 (cross-training boat)
Bring the cunningham into the pit

Double ending the vang and pole down means 4 and not 2 line controllers, as well as deck turns. This means 2 extra clutches and deck organizers, as well as moving the furling line.

The starboard side looks like this; from the inside out:
Vang
Reef
Spinnaker topping lift
Main Halyard
Spin Halyard
Genoa sheet
Genoa car adjuster
Spinnaker foreguy





On Port (inside out):
Vang
Main Outhaul
Cunningham
Genoa Halyard
Asym Tack Line
Genoa sheet
Genoa car adjuster
Spinnaker foreguy




Harder to see but the jib cars have a length of shock cord running from the front of the track to the line lock and back up to the car, helping the car come back with the line is released. Also our tack line is VERY long, allowing us if need be to blow it and pull the asym all the way back into the companionway without having to undo the shackle.
 
The foreguy is now naturally 2:1 with its up-down at the bow. The cunningham and outhaul are as well, with the control line running through the eye and back to a hard point. The vang is now a very powerful 12:1 and requires some special work, as shown in the picture below.






A SS mast base plate is mounted aft of the mast through the deck. A dyneema strop splits the load between the mast base and the plate, and creates an extra 2x for the 6:1 double ended vang, giving the final 12:1.

The stacked deck organizers (available from Beneteau) are shown as well. The the vang plate is sourced from Garhauer Marine at this link. 



The halyards are New England Rope VPC, the genoa sheets are NER T-900. All other lines are NER Stayset. 

The furling line runs down the port side to the stern pulpit, where it is furled by the driver. The block and cleat here not only allows us to secure the line, but by doing so and then pulling hard on the sheets, the furled sail acts like a 'fractlator', pulling the past tip forward when under spinnaker.

The crew is very happy with the layout, and as many also crew on the 36.7 it makes for easy cross training as the 367 looks like this from the factory. Its a great setup.

    Hi,

    I would like to ask how your spipole topping lift line is routed? Through the mast as halyard lines or does it go outside the mast to the block above the spreaders?

    Just ordered a new spinnaker and found out that there is no hole out from the mast for spipole topping line....

    Thru the mast. The exit is about 60cm above the spreaders. The entry is on starboard, lower than the halyards. Strange there was no exit!

Getting an International Certificate of Competence (ICC) in the USA

-

If you are an American sailor with international sailing aspirations, you have probably heard of the ICC. Sometimes described incorrectly as an 'International Sailing Licence' or 'Global Charter Certification', its roots and purpose are more complex, and somewhat strange to Americans. I'll start with a little background. More ancient than automobile driving, mariners (in particular recreational mariners) have long enjoyed a tradition of loose or non-existent licencing of their activities world-wide. Even in well developed countries like the USA, there is very little in the way of formal requirements in order to operate a boat. This has led the world to view American charter skippers as 'Credit Card Sailors', due to the only thing needed with their name on it to sail is their credit card! As often happens in matters like this, the ICC got its start in Europe. The close proximity of countries and the mixing of languages, laws, and cultures made a mis

LED Nav/anchor replacement bulb

-
Image
Depending on the build year and the market, the First 260 often came with a single light at the mast top, most typically a red/green/white navigation light. Designed for offshore/coastal use, the fixture placed the light source high where it was easily seen. The single light has its disadvantage however, the primary one being that there is no provision for an anchor light. You CAN replace the fixture to a stacked nav/anchor light, but beyond that being expensive, you still need to run another set of 12v wires to the top of the mast, and add a switch to your DC panel to control it. So most boats stayed rigged in the original manner. A later option was a LED replacement fixture from NASA Marine in the UK. Called the Combi-LED, this light had the innovative ability to be controlled by ONE 12V wire pair, meaning no new wires to be pulled. It did this by reversing polarity to get anchor light, and came with a small switch to add to your panel to control this. I looked at doing this for

Spinnaker Handling: Twings

-
Image
A recent addition to modern spinnaker handling are a set of control lines called 'twings'. Twings are used to control the position of the spinnaker sheet and guy to shape the sail, and although they are not standard rigging from Beneteau, they are easy to rig on a First 260 or First 25s.   In the picture, you can see both the sheet and guy. Although hidden on the port (guy) side, you can see the twing attached to the sheet of starboard, holding it slightly down to give a better lead angle to the clew. This gives better sail shape. On the pole side, the twing helps the pole-down line control pole position. This diagram gives a good feel for how the lines are laid out. Ideally, you can control the twing from the cockpit as shown. Looking back at the first picture, the control device (F) is a Harken 150 camcleat with a Extreme Angle fairlead on it, mounted on the outer side of the coaming. You can see it easily in the picture. Here it is easily accessible by crew, and
