Modern 16:1 dyneema backstay

-

Nine years ago, I posted about an update I made to the 260 backstay to allow a backstay flicker to be used. That post is HERE. As noted in that post, the factory backstay adjuster does not have enough travel to allow the flicker to pull the backstay away from the leech of the mainsail. The setup worked OK, but had issues.


First up is that it was HEAVY. All stainless wire & shackles, with a heavy 6:1 block system that was cascaded via dyneema through another heavy block to make 12:1. The 12x power was not quite enough, and the heavy 3x block drooped and would hit the driver in the back while standing at the tiller. So it was finally time for an upgrade!




The new system is all 3/16ths (5mm) dyneema, with 2 ceramic low-friction rings creating a 4x multiplier for the small 4:1 tackle. This makes for a VERY LIGHT 16:1 setup. The only suspended SS in the entire setup is the small shackle at the top of the 2x block. On the deck I needed to add a small SS U-bracket to hold the extra purchase. The new bracket is mounted the same distance from the centerline as the port factory eye. An added plus is the backstay is now re-centered on the boat.

The 4:1 tackle has to be long to allow the flicker to pull fully away from the sail. We typically sail with the backstay off in less than 10 knots true wind. We have the setup marked where the backstay is just coming on and effecting bend, so we know where to start when the wind comes up. And with the 16:1, it is much easier to 'block' the purchase to put on full backstay.

A great mod, and I for sure do not miss the old block hitting me in the back!

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

-

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
