We are at the boat show.
The annual POSH regatta was held over the weekend of the 9th and 10th Of May at Paignton Sailing Club. As the venue for the Supernova 2015 Nationals later this year, Team member Iain Horlock took to the water with around 50 other boats for the 2 day event.
Iain was in the non asymmetric handicap fleet of around 15 boats, which included an international moth, a canoe, another supernova, and a group of laser sailors. He ended up 2nd overall, with the international canoe taking an easy first place in force 4-5.
PSC club organised a very slick event, and it will surely be a great event in a months time, with 43 boats already pre-entered.
Having missed their season opener at Stokes Bay, the RS 800 team travelled to Eastbourne Sovereign SC despite the wild forecast for the secong installment of the 2015 Grand Prix series. With the breeze topping 40 knots at times, Saturday was lost to the weather.
Sunday proved a much lighter affair with single string conditions prevailing throughout the day. A solid 6,5,6 result sheet produced the inevitable 6th overall. Phil Walker and John Mather took a deserved victory showing excellent pace and guile in the tricky conditions. Clearly we have a little catching up to do but feel happy with the first event of the year.
More events coming soon…
The 2015 Glyn Charles pursuit race at Hayling Island was well attended on the early May bank holiday Monday. Amongst the 108 strong fleet was Jimmy Green Team Member Iain Horlock in his Supernova.
The race was 2 1/2 hours in total and boats had staggered start times relating to their handicaps. Iain started 36 minutes after the first boats (mirror dinghies) crossed the start line. At this point there were classes starting every minute or two and for the first beat it was very important to get away cleanly. The wind stayed at about a force 2 which meant all the faster boats didn’t have much chance of planing, allowing the slower boats to stay in front. Most of the fleet didn’t even see the two mirrors who stayed far in front of the main contenders around the whole lap of Chichester harbour. Horlock finished 23rd, and was more than happy with that results considering the conditions!
The next event he’s off to is the ‘POSH’ regatta down in Paignton this coming weekend.
The Jimmy Green Marine team will be out and about over the weekend. The RS800 circuit gets under way for Jimmy Green sailors Jamie Trewick and James Green at Stokes Bay SC on the 25th and 26th April. The forecast looks promising for some exciting sailing as the duo look to pick-up where they left off at the end of last season.
Jimmy Green will also have a stand at Beaulieu Boat Jumble on Sunday the 26th of April. Come along and see us for some early season bargains or to discuss your requirements.
Welcome Iain Horlock, the newest member of the Jimmy Green Sailing Team!
The winter season is over and the 2015 season is in full swing!
Iain has recently switched from his previous boat (a contender), to a Mark II Supernova from Hartley boats, and it has already been branded with the Jimmy Green logo in preparation for the upcoming season.
Iain took ownership of the Supernova the day before the new South West winter series started at Roadford Lake on the 8th March. 60 boats turned out for a 2 ½ hour race calculated on average lap times. The boat seemed to be ok and Iain had great fun racing a past national champion round the course, only to be beaten by 5 seconds in the dying moments, finishing 10th overall. A solid start to the season.
The following weekend Iain was off to Starcross for the usually breezy steamer race. This year, conditions were relatively light, Iain managed to stay in front of most of the faster boats to finish 12th out of 80+ entrants.
The final event in the series was the Exmoor Beastie, which always proves to be a tricky event, and this year was no different! After a 3 hour pursuit race in F1-3 Iain was hanging onto 5th place!
As there was no discard and consistency always pays, Iain somehow ended up 3rd overall in the series!

lay along the deck for you to attach your harness safety line.
They can be made from rope, wire or webbing.
Why Webbing ?
Webbing lies flat so is less obtrusive and is kinder to your deck.
Wire and rope may tend to move or roll under your feet.
Wire can be PVC coated to prevent any damage to your deck but this increases the diameter and therefore exacerbates the ‘roll’ problem.
Rope will need to be either more substantial in diameter or relatively ‘high tech’ in order to achieve the same breaking strain.
4mm 1 x 19 stainless steel wire, MBL = 1400kg
5mm 1 x 19 stainless steel wire, MBL 2190kg
High Tenacity Polyester Jackstay Webbing, MBL = 2000kg
The majority of the jackstays we produce are from the 2000kg webbing but we also supply stronger webbing, MBL 3000kg and 4000kg
N.B. All wire and rope splicing and sewing marginally reduces the breaking strain of the finished product.
Where should Jackstays be fitted ?
There are two main considerations:
1. To be able to clip on to the jackstay line while you are in the cockpit and still be able to venture as far forward (and aft) as possible without having to detach yourself.
This means that the jackstay line needs to ‘overlap’ the cockpit domain (it should at least run by the outside of the coaming so you can reach it from inside the cockpit) It also needs to negotiate a path around or over the natural obstacles such as hatches, lower shrouds, grab rails, cleats, windlasses, bollards etc. so that the person clipped on to the jackstay line has a clear path to the forestay/pulpit (or pushpit)
2. To prevent Falling Overboard
This means that the path forward should be as near the centre line as practicable e.g. inside shrouds, over but commonly around the curve of the coachroof.
Clipping on to a jackstay that is too near the guardrail may result in you dangling in the water, especially if you are outside the leeward rail with the yacht heeled going upwind.
N.B. Jimmy Green Bluewater Safety Lines are manufactured to an overall length of 1.5 metres. This is generally long enough to reach the jackstay when you are standing/walking but prevents you falling as far as other safety lines which could be as long as 2 metres. A 1.5 metre line is also more practical for bracing yourself and less likely to tangle, snag or trip you up. 3 hook lines faciltate the changing of attachment points without becoming unclipped. This may be the only practicable solution in awkward, congested deck areas.
Measuring your Jackstays
Both wire and webbing jackstays should be fitted so that there is a degree of lift in the centre of the line before any significant load is applied.
The height of the lift should be proportional to the overall length of the jackstay.
Webbing that is fitted too loose will allow too much slack when a body weight load is applied.
Wire that is fitted too tight may cause excessive load on the end fittings when under load, due to a ‘bowsing’ effect.
A tight wire jackstay may also make it difficult to get the safety hook under the wire.
Selecting your fixing points
Jackstay strong points should be selected according to the principles listed above.
if there are no suitable fixing points in the right position you may need to fit our Jackstay U Bolts
Standard Sewn Loops for attaching to shackles: we can supply extra wide 9mm stainless steel shackles. The shackle is wide enough for the webbing to fit snugly on shackle pin.
Standard Sewn Loops with extra wide shackle included.
Twisted Sewn Loops – These are for passing the other end around e.g. a stanchion base and back through the twisted loop. This creates a ‘cow hitch’ finish that means the loop will sit comfortably on the deck fitting.
Sewn Lanyard Loops – These are bigger loops to allow for multiple reeving of the lanyard.
Sewn Lanyard Loops – Thes are bigger loops with lanyard included
Sewn Loops with stainless steel ring – lanyards can be spliced onto the ring
Sewn Loops with stainless steel triangle – lanyards can be spliced onto the triangle.
Extra wide shackles make a very strong and secure fastening at one end but it may be difficult to achieve the right degree of tension with shackles at both ends.
Lanyards at one end make the measuring, tensioning and fitting more straightforward.
Subtract approximately 200mm – 300mm from the overall length to facilitate the gap filled by the lanyard.
The Dinghy Weekend was another huge success for everyone involved. As ever there was a real buzz around the Palace with everyone involved looking forward to the new sailing season and having tales to tell about their winter exploits – We, Jimmy Green, met loads of new customers, caught up with old friends, sold masses of rope, fittings and sailing kit, and generally had a good time.
We’re looking forward to next year !
Open Saturday the 28th of February and Sunday the 1st of March. Jimmy Green Marine will be there with an extensive range of clothing, ropes and rigging!
We will be on stand D12 in the Great Hall just the same as last year. We will have loads of new products plus a whole host of your favourites from brands including:
Crewsaver, Selden, Barton, Holt, Harken, Spinlock, Marlow, Liros, Clamcleat, Protect, Velocitek, PSP and loads more
See you there…..
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.
