# Westin Sandy Andy: the knife-profile jig for working a deep mooring > From 12 g to over 100 g, how to pick the right Westin Sandy Andy weight for jigging a mooring or rocky point for sea bass depending on depth. - Source : https://carnafish.com/en/leurres/westin-sandy-andy/ - Language : en-US - Updated : 2026-09-05 ## Spec sheet - Brand : Westin - Model : Sandy Andy Jig (10-22 cm range) - Type : Knife-profile sandeel jig - Target species : Sea bass - Size : 10-22 cm depending on model (up to 28 cm in the XXL version) - Weight : 12 g to 122 g depending on size (up to 300 g in the XXL version) - Running depth : surface to 20 m+ depending on the weight chosen - Retrieve speed : variable, from slow vertical jigging to a fast straight retrieve - Action : knife-blade swim, thin lateral profile that flashes on every jerk, pronounced spiral fall - Rigging : built-in head, sturdy single hook from #1/0 to #5/0 depending on size, fluorocarbon or straight braid - Colors : Bleak in clear water, Sardine under overcast skies, Black/Red in deep water or low light The Sandy Andy isn't your average sandeel: its knife-thin, sharp-edged profile throws off a much stronger flash on every jerk and a far more pronounced spiral fall than a standard round-bodied sandeel. Ranging from 12 g to over 100 g in the standard line-up, it's one of the few lures that covers a rocky point in 2 metres of water just as well as a deep mooring past 20 metres, without switching lure styles between the two. ## What the knife shape actually does A round-bodied lure swims predictably and evenly. A knife-bladed one catches light differently depending on its angle to the fish: every rod jerk flips it onto its thinnest plane, throwing off a brief, sharp flash that mimics a panicked sandeel suddenly changing direction. That visual signature, more than the swim itself, is what triggers a strike from a cruising bass. > On the water: on a fish that stays indifferent to a steady swim, a well-jerked knife jig often produces a reaction where a smoother lure only earns a polite follow. ## Choosing weight by depth, not by target fish size This is the most common mistake with this type of lure: assuming weight should scale with the size of fish you're after, when it should actually follow the depth and current of the mark. - **12-22 g**: shallow rocky point or margin, down to 5 metres, weak to moderate current. - **32-42 g**: the most versatile setup, for a drop-off between 5 and 10 metres or stronger current. - **62-82 g**: deep mooring or strong tidal current, past 10 metres, when you need to hold bottom contact without drifting off. - **122 g and up**: vertical fishing from a boat or a high jetty, in significant depths where only a heavy jig reaches bottom quickly. ## Two techniques, two types of ground ### Vertical jigging, for moorings and steep drop-offs From a jetty, a high breakwater or a boat, let the lure sink to bottom, then work it with sharp vertical jerks followed by a pause during which the Sandy Andy falls in a spiral — the strike often comes during that fall, with bass tracking the flash before committing as it slows. ### Fast straight retrieve, for rocky points Fishing from shore on a shallow rocky point, a faster, continuous retrieve punctuated with short jerks mimics a sandeel fleeing through open water rather than a sinking one. This approach suits bass already actively feeding near the surface better. ## The hook: a detail that matters on big bass The Sandy Andy comes rigged with sturdy single hooks ranging from #1/0 on the smaller models to #5/0 on the largest. On a mark known for big bass, don't skip checking the hook size that ships with your model — an undersized hook remains the number-one weak point against a fish well above the local average. ## Colour by depth and light - **Clear water, shallow**: Bleak, a silvery tone that maximises the knife profile's flash. - **Overcast, medium depth**: Sardine, a natural compromise that stays effective in changing light. - **Deep water or low light**: Black/Red, a high-contrast silhouette that stays identifiable even as natural light fades with depth. A deep mooring or an exposed rocky point demand real care around safety and reading the tide before committing — our [guide to fishing sea bass on lures](https://carnafish.com/en/blog/peche-bar-loup-leurre/) covers these precautions and which shore marks to prioritise by tidal coefficient. To find out whether today's depth and current call for a heavy jig rather than a light one, [CarnaFish](https://carnafish.com/en/) reads the tide and current marine conditions from a photo of your spot. ## Key takeaways - The knife profile throws off a stronger flash on every jerk than a round-bodied sandeel. - Choose weight by the depth of the mark, not by the size of fish you're targeting. - Vertical jigging with a paused spiral fall for deep moorings, fast retrieve for shallow rocky points. - Check the hook size shipped with your model on marks known for big bass. ## FAQ ### What Sandy Andy weight suits a rocky point in 3-4 metres of water? Between 12 and 22 g is enough in most cases, with weak to moderate current. Size up if the current picks up or you need extra casting distance. ### How do I work the Sandy Andy while vertical jigging? Let it sink to bottom, then work sharp vertical jerks followed by a pause: the strike very often comes during the spiral fall that follows each jerk. ### Is the Sandy Andy a shore lure or strictly a boat lure? Both, depending on the weight chosen. The lighter 12-42 g models fish very well from shore on a rocky point, while the heavier versions are mainly for vertical jigging from a jetty or boat. ### Why isn't my knife profile flashing enough? Check the sharpness of your jerks: a soft, weak movement doesn't flip the lure onto its thinnest plane, which limits the flash effect you're after. ### What hook size for big bass? Favour models rigged with at least a #3/0 or #4/0 hook on a mark known for big fish, rather than a small model with an undersized #1/0 hook for that class of fish. ### What colour works in deep water? Black/Red, a high-contrast tone that stays clearly identifiable even as natural light fades sharply with depth, unlike a pale tone that washes out. --- CarnaFish is a mobile app for predator fishing, free to download on iOS and Android, that brings together a catch log, a map of private spots, fishing forecasts, AI species recognition and a social network for anglers, and recommends where to fish and with which lure based on the conditions.
