The J\/40 is born out of a long association between J\/Boats in the USA and J Composites in France, a collaboration that created iconic designs including the 36ft J\/109 and 40ft J\/122.<\/p>\n<p>This new model represents a big refinement of successful and well-proven concepts, without losing the ethos and DNA that fans of J\/Boats have come to expect. At the same time, the J\/40 offers a lot more stability and volume than earlier models of a similar size. This translates to faster performance, bigger aft cabin bunks, a better galley, a hugely improved saloon with 18% more volume than the J\/122, better ergonomics and stowage, plus a much higher level of finish.<\/p>\n<p>J Composites says the stability figures are 10% higher than those of the 43ft J\/133, yet the new boat is half a tonne lighter, while waterline length and beam measurements are also more similar to the J\/133 than the J\/122. The result is a boat that can be expected to look after her crew even better in heavy weather, yet also offers excellent performance, even in very light airs.<\/p>\n<p>Immediately noticeable is that the J is still responsive and rewarding to sail in such light breezes. With a true wind of less than 5 knots, boat speed near matches the wind speed when reaching. Unusually among modern yachts it also sailed upwind surprisingly quickly in these very light airs, again with a positive feel on the helm.<\/p>\n<div id=\"attachment_156566\" style=\"width: 640px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-156566\" class=\"size-large wp-image-156566\" src=\"https:\/\/keyassets.timeincuk.net\/inspirewp\/live\/wp-content\/uploads\/sites\/21\/2025\/01\/YAW305.TEST_J_40.241024_j40_sailingenergy783956_4211-630x354.jpg\" alt=\"\" width=\"630\" height=\"354\" srcset=\"https:\/\/keyassets.timeincuk.net\/inspirewp\/live\/wp-content\/uploads\/sites\/21\/2025\/01\/YAW305.TEST_J_40.241024_j40_sailingenergy783956_4211-630x354.jpg 630w, https:\/\/keyassets.timeincuk.net\/inspirewp\/live\/wp-content\/uploads\/sites\/21\/2025\/01\/YAW305.TEST_J_40.241024_j40_sailingenergy783956_4211-300x169.jpg 300w, https:\/\/keyassets.timeincuk.net\/inspirewp\/live\/wp-content\/uploads\/sites\/21\/2025\/01\/YAW305.TEST_J_40.241024_j40_sailingenergy783956_4211-1536x864.jpg 1536w, https:\/\/keyassets.timeincuk.net\/inspirewp\/live\/wp-content\/uploads\/sites\/21\/2025\/01\/YAW305.TEST_J_40.241024_j40_sailingenergy783956_4211.jpg 2000w\" sizes=\"(max-width: 630px) 100vw, 630px\" \/><p id=\"caption-attachment-156566\" class=\"wp-caption-text\">low freeboard along with relatively narrow beam combine to create timeless lines.

When the true wind built to 18 knots it was easy to depower the rig and we were still far from needing to drop a reef in, while making 7.3 knots upwind at an apparent wind angle of 24\u00b0.<\/p>\n<p>The J\/40 also proved to be very flexible upwind. You could choose to maximise speed or maximise height without a measurable difference in VMG, providing sails are trimmed appropriately. On the other hand, despite the extra stability there\u2019s more heel when sailing upwind than some wider beam performance yachts, although the J\/40 can be expected to have a more comfortable motion and be slowed less by awkward head seas.<\/p>\n<div id=\"attachment_156574\" style=\"width: 640px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-156574\" class=\"size-large wp-image-156574\" src=\"https:\/\/keyassets.timeincuk.net\/inspirewp\/live\/wp-content\/uploads\/sites\/21\/2025\/01\/YAW305.TEST_J_40.j_40_a_lindlahr_121-630x354.jpg\" alt=\"\" width=\"630\" height=\"354\" srcset=\"https:\/\/keyassets.timeincuk.net\/inspirewp\/live\/wp-content\/uploads\/sites\/21\/2025\/01\/YAW305.TEST_J_40.j_40_a_lindlahr_121-630x354.jpg 630w, https:\/\/keyassets.timeincuk.net\/inspirewp\/live\/wp-content\/uploads\/sites\/21\/2025\/01\/YAW305.TEST_J_40.j_40_a_lindlahr_121-300x169.jpg 300w, https:\/\/keyassets.timeincuk.net\/inspirewp\/live\/wp-content\/uploads\/sites\/21\/2025\/01\/YAW305.TEST_J_40.j_40_a_lindlahr_121-1536x863.jpg 1536w, https:\/\/keyassets.timeincuk.net\/inspirewp\/live\/wp-content\/uploads\/sites\/21\/2025\/01\/YAW305.TEST_J_40.j_40_a_lindlahr_121.jpg 2000w\" sizes=\"(max-width: 630px) 100vw, 630px\" \/><p id=\"caption-attachment-156574\" class=\"wp-caption-text\">The J is responsive and rewarding to sail in very light airs.

The new J also proved lovely on the helm in all conditions \u2013 finger light with just enough weather helm to give positive feedback.<\/p>\n<p>Overall draught is 2.2m, while the very high aspect rudder is 1.9m deep. This gives a reassuring amount of grip even when the boat is pressed on a reach. At the same time, it offers less drag than twin rudders in light airs and you have the benefit of the prop wash over the central rudder when manoeuvring in tight spaces.

Photo: Andreas Lindlahr\/EYOTY<\/p><\/div>\n<p>With a hull length of just 38ft 5in, this is a shorter boat than the older J\/122E and has more beam, yet it still has a very easily driven hull shape. This was shown when reaching with only main and jib in 12 knots true, when we still made 7 knots in a really easy cruising mode. On bearing away to 140\u00b0 true and deploying the 130m2 top-down furling gennaker we made 8.5 knots as the wind built to 14 knots. Boat speed increased to 9 knots when we luffed up by 35\u00b0, yet this was still easy sailing, without feeling pressed.<\/p>\n<p>The shortish 77cm fixed sprit, in place of a much longer retractable version, is a clear break with J\/Boats tradition. Nevertheless, even in light airs it never felt as though this is a brake on performance and, equally, the big 160m2 A2 spinnaker ought to be large enough to promote planing performance, even if more wind will be needed than for proportionately lighter boats such as the First 36, Pogo 44, or JPK39 FC.<\/p>\n<p>Conventional wisdom also says that commercially successful performance yachts have to be optimised to a rating system. However, J\/Boats has consistently bucked the trend in this respect. Indeed, the initial success of the J\/24 almost 50 years ago was precisely because it didn\u2019t pander to any rating system, which allowed Rod Johnstone to draw a boat with very fair lines that performed and handled far better than other small raceboats of the era.<\/p>\n<div id=\"attachment_156569\" style=\"width: 640px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-156569\" class=\"size-large wp-image-156569\" src=\"https:\/\/keyassets.timeincuk.net\/inspirewp\/live\/wp-content\/uploads\/sites\/21\/2025\/01\/YAW305.TEST_J_40.241024_j40_sailingenergy786269-630x354.jpg\" alt=\"\" width=\"630\" height=\"354\" srcset=\"https:\/\/keyassets.timeincuk.net\/inspirewp\/live\/wp-content\/uploads\/sites\/21\/2025\/01\/YAW305.TEST_J_40.241024_j40_sailingenergy786269-630x354.jpg 630w, https:\/\/keyassets.timeincuk.net\/inspirewp\/live\/wp-content\/uploads\/sites\/21\/2025\/01\/YAW305.TEST_J_40.241024_j40_sailingenergy786269-300x169.jpg 300w, https:\/\/keyassets.timeincuk.net\/inspirewp\/live\/wp-content\/uploads\/sites\/21\/2025\/01\/YAW305.TEST_J_40.241024_j40_sailingenergy786269-1536x864.jpg 1536w, https:\/\/keyassets.timeincuk.net\/inspirewp\/live\/wp-content\/uploads\/sites\/21\/2025\/01\/YAW305.TEST_J_40.241024_j40_sailingenergy786269.jpg 2000w\" sizes=\"(max-width: 630px) 100vw, 630px\" \/><p id=\"caption-attachment-156569\" class=\"wp-caption-text\">Cockpit is spacious, even though maximum beam is not carried as far aft as on most of today\u2019s designs.

Photo: Sailing Energy\/J Boats<\/p><\/div>\n<p>Our test boat was fitted with an optional carbon mast with rod rigging in place of the standard aluminium spar with Dyform wire rigging. It was also set up with a Harken Mk lV removable headsail furling drum, allowing the use of a furling headsail for cruising or full luff length racing sails. To change mode you simply undo six Allen screws, allowing the drum to be removed.<\/p>\n<p>The choice of an above-deck furler was a deliberate one that makes sense for this boat. For a start, the furling lead has a more direct run, which reduces friction compared to a below deck unit. It also allows the forestay to be positioned right on the bow, thus maximising the J measurement. Headsail sheets are led via old school longitudinal jib sheet tracks with inhaulers.<\/p>\n<p>For efficient upwind work in stronger breezes there\u2019s also an option for a furling staysail with a halyard lock and 2:1 purchase at the tack that leads aft to a winch to tension the luff before being locked off on a foredeck clutch. It\u2019s a neat system that can be set up in advance of heavy weather, but removed to making tacking easy when it\u2019s not needed.<\/p>\n<div id=\"attachment_156577\" style=\"width: 640px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-156577\" class=\"size-large wp-image-156577\" src=\"https:\/\/keyassets.timeincuk.net\/inspirewp\/live\/wp-content\/uploads\/sites\/21\/2025\/01\/YAW305.TEST_J_40.j_boats_j40_lfr7386_ludovic_fruchaud-630x354.jpg\" alt=\"\" width=\"630\" height=\"354\" srcset=\"https:\/\/keyassets.timeincuk.net\/inspirewp\/live\/wp-content\/uploads\/sites\/21\/2025\/01\/YAW305.TEST_J_40.j_boats_j40_lfr7386_ludovic_fruchaud-630x354.jpg 630w, https:\/\/keyassets.timeincuk.net\/inspirewp\/live\/wp-content\/uploads\/sites\/21\/2025\/01\/YAW305.TEST_J_40.j_boats_j40_lfr7386_ludovic_fruchaud-300x169.jpg 300w, https:\/\/keyassets.timeincuk.net\/inspirewp\/live\/wp-content\/uploads\/sites\/21\/2025\/01\/YAW305.TEST_J_40.j_boats_j40_lfr7386_ludovic_fruchaud-1536x864.jpg 1536w, https:\/\/keyassets.timeincuk.net\/inspirewp\/live\/wp-content\/uploads\/sites\/21\/2025\/01\/YAW305.TEST_J_40.j_boats_j40_lfr7386_ludovic_fruchaud.jpg 2000w\" sizes=\"(max-width: 630px) 100vw, 630px\" \/><p id=\"caption-attachment-156577\" class=\"wp-caption-text\">The interior has more wood trim than earlier J\/Boats of a similar size.

The J\/40 is born out of a long association between J\/Boats in the USA and J Composites in France, a collaboration that created iconic designs including the 36ft J\/109 and 40ft J\/122. This new model represents a big refinement of successful and well-proven concepts, without losing the ethos and DNA that fans of J\/Boats have come to expect. At the same time, the J\/40 offers a lot more stability and volume than earlier models of a similar size. This translates to faster performance, bigger aft cabin bunks, a better galley, a hugely improved saloon with 18% more volume than the J\/122, better ergonomics and stowage, plus a much higher level of finish. J Composites says the stability figures are 10% higher than those of the 43ft J\/133, yet the new boat is half a tonne lighter, while waterline length and beam measurements are also more similar to the J\/133 than the J\/122. The result is a boat that can be expected to look after her crew even better in heavy weather, yet also offers excellent performance, even in very light airs. Immediately noticeable is that the J is still responsive and rewarding to sail in such light breezes. With a true wind of less than 5 knots, boat speed near matches the wind speed when reaching. Unusually among modern yachts it also sailed upwind surprisingly quickly in these very light airs, again with a positive feel on the helm. Once the breeze picked up to 8.5 knots we made 6.6 knots upwind, even though we were sailing with a cruising spec woven polyester furling headsail. By the time the true wind built to 12.5 knots we were well powered up with 7.4 knots of boat speed at an apparent wind angle of only 26\u00b0. Depowering as the wind continues to build is easy thanks to the powerful hydraulic backstay, an efficient mainsheet traveller that runs across the cockpit floor and the German mainsheet system. These work together to simplify accurate mainsail trimming in a manner that simply isn\u2019t possible in most cruising yachts. Article continues below&#8230; This was borne out on my first sail on the boat during a blustery late October day in Palma, with frequent heavy squalls interspersed with calmer periods. When the true wind built to 18 knots it was easy to depower the rig and we were still far from needing to drop a reef in, while making 7.3 knots upwind at an apparent wind angle of 24\u00b0. The J\/40 also proved to be very flexible upwind. You could choose to maximise speed or maximise height without a measurable difference in VMG, providing sails are trimmed appropriately. On the other hand, despite the extra stability there\u2019s more heel when sailing upwind than some wider beam performance yachts, although the J\/40 can be expected to have a more comfortable motion and be slowed less <a href=\"https:\/\/www.yachtingworld.com\/reviews\/boat-tests\/grand-soleil-40-review\">&hellip;Continue reading &raquo;<\/a><\/p>\n","protected":false},"author":450,"featured_media":156565,"comment_status":"open","ping_status":"closed","template":"","tags":[248,1469,1633],"review_manufacturer":[],"review_category":[295],"review_type":[293],"review_award":[],"acf":[],"_links":{"self":[{"href":"https:\/\/www.yachtingworld.com\/wp-json\/wp\/v2\/review\/156562"}],"collection":[{"href":"https:\/\/www.yachtingworld.com\/wp-json\/wp\/v2\/review"}],"about":[{"href":"https:\/\/www.yachtingworld.com\/wp-json\/wp\/v2\/types\/review"}],"author":[{"embeddable":true,"href":"https:\/\/www.yachtingworld.com\/wp-json\/wp\/v2\/users\/450"}],"replies":[{"embeddable":true,"href":"https:\/\/www.yachtingworld.com\/wp-json\/wp\/v2\/comments?post=156562"}],"version-history":[{"count":5,"href":"https:\/\/www.yachtingworld.com\/wp-json\/wp\/v2\/review\/156562\/revisions"}],"predecessor-version":[{"id":156583,"href":"https:\/\/www.yachtingworld.com\/wp-json\/wp\/v2\/review\/156562\/revisions\/156583"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.yachtingworld.com\/wp-json\/wp\/v2\/media\/156565"}],"wp:attachment":[{"href":"https:\/\/www.yachtingworld.com\/wp-json\/wp\/v2\/media?parent=156562"}],"wp:term":[{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.yachtingworld.com\/wp-json\/wp\/v2\/tags?post=156562"},{"taxonomy":"review_manufacturer","embeddable":true,"href":"https:\/\/www.yachtingworld.com\/wp-json\/wp\/v2\/review_manufacturer?post=156562"},{"taxonomy":"review_category","embeddable":true,"href":"https:\/\/www.yachtingworld.com\/wp-json\/wp\/v2\/review_category?post=156562"},{"taxonomy":"review_type","embeddable":true,"href":"https:\/\/www.yachtingworld.com\/wp-json\/wp\/v2\/review_type?post=156562"},{"taxonomy":"review_award","embeddable":true,"href":"https:\/\/www.yachtingworld.com\/wp-json\/wp\/v2\/review_award?post=156562"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
