A heavy frog that does not go down is not automatically a frog with too much friction. It can be loaded by the drizza, the vang, the slag, or the direction of the boat. On Ronstan Series 26 the diagnosis must separate these effects from the 26 mm rail, gate and trolleys. The decisive test does not consist of pulling stronger downwards: it is to remove a load at a time, observing if the behavior changes without exposing the crew.
Put the boat in condition before trying
The manoeuvre is carried out with suit and compatible wind, area under the free frog and clear communication. They are gradually discharged and vang and it is checked that the straightness can row without overlap. No one is placed under components or sailing in motion. If it is necessary to work at altitude, it intervenes competent personnel with appropriate systems; the diagnosis from the bridge does not authorize improvisations.
Weight should not be confused with a block
A large surface sail has inertia and may require an ordered management, but the force should change progressively. A net stop at the same altitude indicates a geometric point; a slow descent along the whole race suggests distributed friction or load still present. It describes the symptom before intervening, distinguishing reduced speed, hard point and visible inclination of a cart.
Profile identification and variant Series 26
The family includes mast track and luff groove, 69mm wide traditional trolleys and 52 wide goats in the main components. Codes, section and gate type are noted. A trolley for luff groove is not replaced with a standard variant for similarity. The correct identification prevents a spare test to introduce a second defect in the track.
The 325mm gate deserves dedicated control
The mast track uses a gate of 325mm with five slugs and M6 screws; the luff groove has its own opening trait of the same length. Clamping, alignment, fixing heads and edges are observed. If more trolleys change resistance at the gate, you do not file or force the passage: the expected continuity is restored.
The joint locates repeatable defects
The mast track and luff groove use dedicated union systems. When all bodies hesitate to the same altitude, they compare that position with joints. The test is discharged and with a held cart. A step can only appear when the rail is loaded, so it repeats at moderate voltage observing from safe distance, without exceeding the point with a winch.
An intermediate allows the cleanest comparison
The traditional intermediate measures 70 for 69 mm, captive 64 for 52. By not getting the compression of a stick directly, it helps to understand whether friction belongs to the track. If it exceeds the quota where the rapid stops, the attention passes to the connection of the stick. If you brake in the same way, the profile, the gate or a fixing become priority.
Clean without canceling the diagnosis
Salt and particles increase friction. The system is rinsed with fresh water and left to drain, then the test is repeated in the same conditions. You do not add generic lubricants to get a temporary descent: they can retain dirt or alter the response. If resistance remains, mechanical analysis continues instead of covering the symptom.
The pen can hold loaded all the frog
The traditional pen trolley is 225 mm long and 69 wide; the captive measures 236 for 52. At the top you control the right angle, tablet and freedom of connection. If the straightness leads the body against a edge, the friction can prevent the start of the descent. By reducing the voltage in a controlled manner, it is observed if the cart returns to the axis.
The table distinguishes symptom, load and track
| Symptom | First hypothesis | Competition | Action prohibited |
|---|---|---|---|
| Slow down everywhere | Residual or dirty load | Scotta, vang, straight | Pull from the fabric |
| Arrest at the same altitude | Gate, coupling, fixing | Second exhaust trolley | Force to the winch |
| Only the quick stops | Steak or recipe | Intermediate on the quota | Enter the link |
| Only to the reef | Borosa and trolley reef | Progressive tension | Cazzarella |
The stick can tilt the fast
The traditional quick-release measures 110 for 69 mm and captive 115 for 52. The recipe must articulate without getting to joke. If the stick is compressed or rotated, the cart can work on the edge and brake. It compares the race with reduced load, without opening the rapid until the sail is held independently.
Pen plates must remain aligned
A loose fixing, a deformed hole or a rotating board can turn the traction of the straight into a lateral component. The inspection seeks abnormal play and contact marks, without accidentally tightening under load. If the plates or the cart are deformed, the test ends and intervenes a competent sailor or tool.
Reef changes the direction of forces
The traditional and captive reef trolleys are 90 mm long, with widths 69 and 52. When the sail is reduced, the borosa and the new wall point can drag the body laterally. A frog that goes down well in full sail but it blocks to the hand requires control of the rivii, not only of the track. Each voltage is applied slowly.
The luff groove has a throat of 11.5 mm
The 2.025 or 3.025 mm profile and its joiners form a specific architecture. It happens that the trolleys correspond and that the throat has not been deformed or obstructed. No 26mm rated measurement is used as the only compatibility test. Standard and luff groove share the family, but not every interface.
The captive spheres remain in the body, the cart no
Ball retention simplifies some operations, but the curve continues to hold the body on the rail. Before opening gates or terminals a containment system is prepared. The cart can fall, bump the blanket or drag the sail even without losing balls. Captive describes the internal circuit and does not replace a safe procedure.
End cap and end stop are not interchangeable
The plastic cap measures 34 for 32 mm; the alloy wheelbase 55 for 45. The first finishes the profile, the second arrests the trolleys. If the problem appears at the bottom, it is checked that the stop is stable and does not interfere. It does not rely on the weight of the sail to a hood or a temporary solution.
The sail package can create the defect during the lowering
As the trolleys concentrate below, fabric and spools can press on the gate or tilt the bodies. It is observed how the frog enters the lazy bag and is distributed on the boma. If the resistance grows only in the final part, the collection is reorganized without putting hands between moving trolleys. The problem can be outside the track.
Compare climb and descent reveals the dominant carrier
If the hard point appears only by hiring, you control traction of the drizza and pen. If it appears only coming down, they become central gravity, sail collected and lateral loads. An identical arrest in both directions suggests a stable obstacle. The two maneuvers are recorded separately and not considered equivalent tests.
Noise and force must be related
A hit on the joint, a continuous scraping or a silent increase in resistance indicate different phenomena. It locates the sound without approaching the charged parts. If noise and force grow together, the maneuver stops. Repeat many times to confirm can damage balls, profiles or fixes and does not add useful information.
Some feedback impose immediate stoppage
Crepes, deformed bodies, missing spheres, folded rails, mobile gates, protruding fixes or damaged tailgates close the test. The sail is secured and documented code and quota. The onboard diagnosis does not replace a structural repair and should not turn into a series of temporary adaptations on a loaded system.
The final test proceeds by levels
After cleaning or intervention approved, a restrained cart runs along the drain. It then tries moderate tension sailing, observing pen, fast and gate. Finally, the reef occurs. The result must be repeated without new noises or sudden variations. Only one successful descent does not show that the cause has been removed.
The technical card makes control repeatable
Type of rails, codes, gate position and joints, fault share, loads present and result of the tests are recorded. Photos of fixings and connections complete the track. The next inspection will be able to compare data and not impressions, while the professional will be able to arrive with the correct replacement and an already limited diagnosis.
The time used to leave is a measurable data
A frog may not be blocked but take a few seconds before you start descending. The delay is observed without timing a dangerous situation and compares with the tensions present. If you simply lighten the vang because the descent begins, the residual load is part of the explanation. If the delay remains with all properly discharged maneuvers, they become more important distributed friction, pen out axis and accumulation of particles.
The temperature and time under load can change the response
After a long boline, sailing and rig are not in the same conditions as the mooring test. It is noted if the problem appears only after hours of loading, without using this difference to continue an abnormal manoeuvre. A variation related to use may indicate a deposition, misalignment or contamination that moves. The comparison must be repeated in a controlled manner and communicated to the technician with the set in which it appeared.
The assisted collection should not drag the trolleys
Lazy jack, lazy bag and operators help rule the fabric, but do not have to pull the sail sideways while the bodies descend. It is checked that the tops do not catch a stick and that the fabric does not fall between tree and cart. Those who collect accompanies the sail without using it as leverage. If you release the collection system the descent returns regular, the track should not be modified: you need to correct the external management.
A video comparison is only useful if the maneuver remains safe
A recovery can show the moment when a quick wheel or the sail package presses on the gate. The room is positioned without creating obstacles and there is no violent stop to get a better image. They compare up and down frames, connecting them to the scored share. The video integrates codes and observations, but does not replace the close inspection performed by competent personnel.
A heavy frog must come down for controlled causes
Gravity alone does not guarantee manoeuvre, but each resistance must have a consistent explanation. Download the maneuvers, identify the variant, compare intermediate and fast, check gate and reef separates load and friction. The Series 26 comes back reliably when the frog drops without a component to win or compensate for the next one.
