Halyard and Sheet Selection Guide

Jimmy Green Marine offer a comprehensive range of braided lines suitable for use as a halyard or sheet, but which one will suit you? The length can easily be specified by measuring an existing halyard or sheet and can even be guessed fairly accurately from schematics if you are familiar with your deck layout. The difficulty arises when considering the material to be used, the construction and the diameter of the rope. These factors have a significant influence on the overall cost and performance of your line. This guide aims to help you choose the right line at the right price.

There are many more fibres available for the truly discerning sailor, however this article sets out the 5 most common ones found in our product range. Listed in order from most expensive to most economical they are: Vectran, Dyneema, Technora, Polyester and Polypropylene.

- Vectran is the strongest and most expensive fibre and has very low elongation over time (creep). It is commonly impregnated with a UV stabiliser.

- Dyneema is very nearly equal to Vectran in terms of strength and stretch and is also usually impregnated with a UV protective coating.
The price advantage over Vectran makes this a popular choice with rope manufacturers at the upper end of the market.

- Technora has very high abrasion and UV resistance and is commonly blended into the cover/jacket of a braid on braid line.

- Polyester is the most common fibre with excellent UV resistance, good breaking strains and low stretch characteristics. It is available in a bright monofilament fibre and a softer, matt finish, spun yarn.
Bright polyester fibres are low stretch  e.g. braid on braid bright white polyester.
The softer feel, spun yarn has less strength and is slightly stretchier. Spun yarn is typically used for the cover/jacket on e.g. 16 plait matt polyester

- Polypropylene is the lightest (doesn’t absorb water) and cheapest fibre. However it is stretchy and susceptible to UV.

Rope manufacturers have traditionally used different fibres for the core and the cover in order to make the most of their relative advantages but can now produce even better ropes by blending different fibres together in either the core or the jacket.

The majority of lines are comprised of a braided core and a braided jacket.
The most common cruising lines are 100% polyester (cost effective).
The weight of fibre in these lines is usually balanced equally between the cover and the core and can be spliced using the double braid splice.
Marlowbraid is the exception as it has a 3-strand core which slightly reduces stretch for a very modest increase in price. The downside of this construction is that it tends to flatten around sheaves and winches.

N.B. braided lines with a polypropylene core may make a saving but will be reflected in a marked lack of performance particularly with regard to extra stretch where it is not desirable.

The construction of the cover also has a bearing on abrasion resistance. Generally the covers with a tighter weave or ‘more plaits’ e.g. 8, 16, 24, 32 plait offer a sliding scale of improved wear resistance.

Stronger fibres such as Dyneema or Vectran are required to significantly increase the strength of a line and reduce it’s stretch. Typically, these fibres are used in the core which is therefore much stronger than the cover.
These lines then have to be spliced using the core dependent method which in turn means the weight of fibre in the cover can be reduced.
Therefore the cost is directly related to the strength and stretch which in turn is governed by the amount of dyneema/vectran content in the finished rope.

It therefore follows that the the strongest line for a given diameter does not have a cover and is 100% ‘core’. However, Halyards and sheets still rely on the cover for grip and abrasion resistance in clutches and on winches. The solution is to strip the cover from the core shortly after the winch or clutch. This can only be done with core dependent ropes.

All the fibres mentioned can be blended to produce covers with different properties. Racers may use a polypropylene/dyneema blend for lightweight sheets or a technora/polyester blend for sheets that get through a lot of work. Cruisers are less likely to have sailing condition specific requirements, so, a standard polyester cover heavy enough to give good longevity is usually the best bet.

So how does this help? The full range of lines supplied by Jimmy Green Marine can cater for both the cruisers and the racers. So we have arranged the lines on a sliding scale below to help you decide where to aim. Whether you’re a cruiser looking to strengthen up your lines for a more adventurous outing or a racer looking for a better price point Jimmy Green has a line for you.


Rope Cover Core Stretch
Liros 16plait Matt Polyester Polyester 5%
Liros Braid on braid Polyester Polyester 5%
Marlowbraid Polyester Polyester 4%
Liros Herkules Polyester Polyester 5%
Marlow D2 Competition Polyester Dyneema 2%

Replacing your rigging with Jimmy Green

Thinking of replacing all or part of your standing rigging? Jimmy Green Marine offer a mail order rigging service for rapid delivery of replacement stays. Here are some tips for making sure you get it right.

Preserve your settings. If you’ve kept a keen eye on your settings and have arrived at the best set-up, you will want to be able to accurately replicate the settings. Mark the existing bottle screws by applying tape to the thread at both ends of the rigging screw. This will allow us to recreate your setting in the trough if you are sending us your wire or allow you to recreate them once the mast is down.

Jimmy Green measure from the bearing edge to the bearing edge (BE to BE) of all fittings. Clevis pin diameters therefore need to be specified separately. If you are ordering a new stay complete with rigging screw, the new stay will be supplied with the original BE to BE measurement with the bottle screw 2 thirds open. When ordering a wire with one end swaged and the other end blank, we will measure from the BE of the swaged fitting to the end of the wire. When ordering a wire with a stud and swaged fitting, we will measure from the BE of the swaged fitting to the end of the stud.

Unless stated, we will send your existing rigging back to you with your new wires. If you are at all unsure of the final specification then please feel free to email photos of your existing fittings so that we can check them for you. We are always happy to load the job into the calculator for you to get a quick quote.

You may be lucky enough to have a rigger nearby or know of a mobile service that can help. However, Even if you have these options, it may be worth using the quick rigging calculator to compare prices. Jimmy Green Marine have a convenient website tool that can give you a quick idea of the costs involved. Simply choose your wire type, diameter, length and end fittings to receive the instant quote.—rigging/wire-rigging

Turning the quote into an order is easily realised with a click of the button. We aim to stock all parts and hope to turn orders around within 5 days even in the busy part of the season.

How should my helmet fit?

The ski season is now in full swing. Skiers and boarders alike will be pulling their kit out to see how it has faired in storage. Typically, it won’t look as good as you remember it when you put it away. Assessing the condition of clothing is relatively easy, we are familiar with our size and happy to choose our own style.

However, Helmets are not an everyday item and require a little closer scrutiny as an integral part of any skiers/boarders safety kit. Please see a brief summary below of how to review your existing helmet and what to look out for when purchasing a new one.

You own a helmet:
Take a moment to reflect on last years ski season. How did the helmet fair? Was it involved in any impacts? Whether it rolled off the table at lunch, you dropped it in the bar or you hit a tree, all the bumps add up to fatigue in the structural integrity of the helmet. Any impact on the shell should be reason enough to consider a replacement. Visible scratches and dents are good reminders but not all the damage will be visible. How are the liners fairing, a good seasons use can crush the padding so check it is all in good order and ready to keep that helmet snugly attached to your head.

Thinking of getting one:
Shape is the most important thing here. If it is the right shape, it will be a comfortable fit. A comfortable fit will enhance the chances of a safe fit. Some pointers below:
– The helmet should sit right down on the top of your head. It needs to make contact!
– It also needs to be a firm fit. Shake your head, does the helmet wobble in any plane?
– Firm does not mean tight! Any tight spots may add up to a head ache. Remember you will be wearing it for anything up to 6 hours a day.
– Try looking in the mirror, without pushing the helmet down on your head, can you move your eyebrows by moving the helmet? If yes, the helmet is nicely connected to your head in lots of spots. Therefore no voids and a reduced potential for the helmet hitting your head in an impact before it can absorb the blow.

It is worth remembering that different brands have different shapes so don’t get disheartened if the shape doesn’t work. There are plenty of brands out there. Once you know which shape works, it’s time to delve into that shape to find the colour that best suits your jacket!

Stay Safe,

Jimmy G

A quick guide to choosing a windlass.

If you are considering purchasing a windlass then selecting the right model is critical for long term performance and ease of use. There are two common types of Windlass available as shown in the pictures below.

Vertical (below left) and horizontal (below right). This relates to the orientation of the axis around which the gypsy rotates.

Aesthetics: The deck footprint of a horizontal windlass is larger due to the entire unit being above deck. The vertical set-up reduces clutter on deck by hiding the motor and gear box in the chain locker. Mounting space in the chain locker must therefore be considered.

Gravity: The windlass is designed only for retrieving the ground tackle. It is gravity that stores the ground tackle. When all the ground tackle is on board, there must still be a minimum of 30cm (12 inches) of drop from the gypsy to the top of the pile. A horizontal windlass stands higher above the deck so the pile can theoretically be closer to the top of the chain locker.

Pulling power: Once you have decided upon the configuration then you can evaluate how much power you need. Lewmar and Lofrans offer two slightly different calculations  based on information they supply.

Lewmar suggest that the maximum pulling power of the windlass should be greater than 4 x the total ground tackle weight. So if your ground tackle weighs 50kg including your anchor chain and rode then the maximum pull of the windlass should be greater than 200kg.

Lofrans suggest that the total ground tackle weight should be 25% less than the specified working load limit of the windlass. If your ground tackle weighs 50kg then the specified working load limit of the windlass should be greater than 66.7 kg (divide the weight by 0.75).

Both brands offer guides on suitable vessel lengths for each model of windlass. This should be considered in conjunction with the ground tackle calculations and displacement variations from the accepted average for a vessel of a given length.

If you have any further questions, or would simply like us to help with your specifications then please get in touch via or give us a call on 01297 20744. Alternatively, feel free to view our windlass section here Windlasses.

PBO Best Budget Buy: Our Yacht Drogue!

PBO wrote: Jimmy Green, based in Beer in East Devon, make a number of sizes of drogue – this one was a Size 10, suitable for Mohraina’s 29ft. It comprises a PVC cone. At low revs, it reduced our speed from 3.5 knots to 2 knots. exerting 28kg on the line. Flat out, it reduced the boat speed from 7 to 4.5 knots, exerting 100kg on the line. It set immediately on immersion despite the lack of any stiffening to hold the mouth of the cone open, and behaved well underwater, with no spinning, slewing or porpoising. A short length of chain helped keep it submerged. It was simple to recover, and a tripline will help to collapse the drogue on recovery. PBO, July 2014.
