On board the Stem 50 are halyards, sheets and boat ropes made by a true Italian excellence, such as Gottifredi Maffioli. It is Luca Sabiu himself, ocean navigator and \u2018Navigation Advisor\u2019 to the Stem Marine team, who reveals how they were chosen and how they make driving this cabin cruiser simple, pleasant and safe.<\/strong><\/strong><\/p>\n\n\n\n

On board a sailing cabin cruiser, among the essential components are the boat ropes <\/strong>and halyards <\/strong>to which we entrust not only the setting of the sails<\/strong>, but more generally the running of the hull <\/strong>and the safety of navigation<\/strong>. Choosing quality sheets and halyards can only enhance the characteristics of the boat and its performance, and facilitate the work of the skipper and crew.<\/p>\n\n\n\n

That is why the Stem Marine team for the ropes and cables of the Stem 50, a 15.85 metre aluminium cabin cruiser destined for the great outdoors<\/strong>, chose a partner of excellence: the historic Gottifredi Maffioli brand<\/strong>. The quality of the leading Italian company in this sector is widely appreciated. It is valued on cruising cabin cruisers as well as on mega yachts and racing boats, from the Imoca 60 of the Vend\u00e9e Globe<\/strong> to the AC75 of the America’s Cup<\/strong>.<\/p>\n\n\n\n

So let’s see what ropes and cables are installed on board Stem50<\/a><\/strong> and what advantages they offer in boat handling, with the help of Luca Sabiu<\/a><\/strong>, ocean navigator and sailing coach. In fact, he personally took care of the entire deck and rigging of the Stem 50, using all his expertise in the ocean aboard racing and cruising boats.<\/p>\n\n\n\n

Study of work loads and rope diameter<\/strong><\/strong><\/h2>\n\n\n\n

It is Luca Sabiu himself who reveals what Stem Marine<\/a><\/strong>‘s approach was when choosing which lines and cables to take aboard the Stem 50. Each manoeuvre was the result of a careful and detailed study. “The first step in the work was to define the specific loads for each manoeuvre<\/strong>, i.e. sheets, halyards, tack and reefing hands. Once the loads were identified, we moved on to the choice of individual materials. The aim was to obtain lines with diameters as small as possible, obviously without exaggerating, because lines that are too thin are then more difficult to adjust,<\/strong> just think of the spinnaker sheets. However, a smaller diameter significantly improves the passage of the lines through the organiser systems and pulleys installed on deck,” he says.<\/p>\n\n\n\n

A fundamental concept is that all halyards in a cabin cruiser must be in perfect synergy with the deck plan<\/strong>. To give an example: there is no point in choosing a 12 millimetre halyard if the stoppers are calibrated for 10 millimetres. The choice of lines therefore cannot be made in isolation, but must be part of a coherent design <\/strong>that takes into account every single component of the deck plan. It is a concept that is often overlooked, but when the time comes to execute the manoeuvre, one realises that it \u201cdoes not turn\u201d as it should.<\/p>\n\n\n\n

Material choices: top ropes and socks<\/strong><\/strong><\/h2>\n\n\n\n

When it came to the choice of materials for the boat ropes and sheets with which to equip the Stem50, the Stem Marine team made no compromises: a very high level of quality was adopted. Proof of this are the Stem50’s ropes, which all have a core of Dyneema DSK <\/strong>78 by Gottifredi Maffioli<\/a><\/strong>. This material is an absolute guarantee in terms of strength, weight and durability. In addition to the core of the ropes, great attention has also been paid to the choice of socks<\/strong>.<\/p>\n\n\n\n

The most heavily loaded manoeuvres, such as tacking and halyards, have been made with Technora socks. This high-tech material offers excellent \u201cgrip\u201d and works perfectly with stoppers and winches, keeping the manoeuvre \u201cfirm\u201d once in traction. The sheets, on the other hand, have been fitted with polyester socks, which are softer and more pleasant to the touch.<\/p>\n\n\n\n

Custom work and \u201ccovers\u201d at critical points<\/strong><\/strong><\/h2>\n\n\n\n

Stem 50 was born as a project that can be customised <\/strong>in many aspects. Even the ropes, halyards and cables of this offshore cabin cruiser are no exception. \u2018All the lines on board the Stem 50 <\/strong>have been customised,\u2019 explains Sabiu. “In practice, each one, in its use, has specific friction points that are stressed thousands of times more than the rest<\/strong>. Take, for example, a halyard working on a sheave at the masthead: the 20-30 centimetres of line that continuously run at that point are subjected to intense wear. We took our inspiration from the world of racing to apply so-called \u201ccovers\u201d<\/strong>, already widely used on maxi yachts and ocean-going boats, to those critical points”.<\/p>\n\n\n\n
