Few anglers on Cape Cod have put in the hours that Ian McPartland and Calvin Toran-Sandlin have. Ian works at the Goose Hummock, where he leads everything related to surfcasting. Calvin is a veteran boulder field angler and skisher whose willingness to snorkel the bottom — literally — to understand what fish are feeding on says everything you need to know about his approach.
Both grew up fishing Cape Cod's beaches and have spent countless nights casting into the suds in pursuit of trophy stripers. What follows is a breakdown of their approach, covering how each of them approaches reading the beach, what real preparation looks like, how to identify feeding windows, and the plug selection strategies that have produced big fish for each of them over many years.
Ian and Calvin are two of the featured instructors in our April Surfcasting Zoominar Series, where they'll spend two hours going even deeper on reading the beach, finding trophy stripers, and the techniques that have produced big fish for each of them over many years.

Reading the Beach [01:55]
Ian and Calvin fish very different environments — and that's exactly what makes their perspectives so valuable together.
Calvin: Boulder Fields and Resident Bait
For Calvin, reading a boulder field is less about reading the beach itself and more about reading the entire environment.
"You're going to look for classic features — structure, water movement, be that sweep or wash. Those are going to hold true whether you're in a boulder field, you're on a breachway or rip line, or you're fishing a sandy beach."
The key difference in boulder field fishing is the bait profile. While many surf anglers focus on migratory schooling bait — bunker in the fall, herring in spring — Calvin's primary focus is on resident baitfish that hold in the rocks year-round:
- Juvenile tautog
- Scup
- Fluke
- Crustaceans and lobster
These are the forage species that live in the boulders throughout the entire season, not just during a migration window. As the season progresses, other baits filter through:
- Squid in the spring
- Mullet and peanut bunker later in the season
Calvin adjusts his approach as those seasonal bait patterns come and go, but his foundation is always understanding what resident bait is present and how it interacts with the structure.
Ian: Sandy Beaches and Constant Change [03:42]
Ian fishes the sandy beaches of the National Seashore on the outer Cape — an entirely different challenge. Unlike boulder fields, which remain relatively consistent season to season, sandy beaches are in constant flux.
"The beach that was super hot last year is almost guaranteed to not be super hot this year."
Ian's approach to this: preseason scouting with zero intention of fishing. Before the season begins, he walks beach after beach at dead low tide — no rod, nothing in the car — just scouting. He may cover the equivalent of two or three towns' worth of shoreline in a single afternoon to map out:
- Where bars and troughs have shifted
- Where baitfish are likely to hold
- Which spots have changed dramatically over the winter
Because 90% of his actual fishing happens at night, this daytime recon gives him a critical mental map. When he arrives at a beach after dark, he already knows what to look for and where.
The Work Behind the Fish [05:30]
One of the most important themes from this seminar is how much work goes into catching a trophy striper — work that happens long before anyone picks up a rod.
Calvin has been known to put on a wetsuit and snorkel the bottom of his fishing spots to see firsthand what's living there:
- What baitfish are present
- What crustaceans are holding in the rocks
- What the structure actually looks like beneath the surface
Ian puts in equally serious time, using Google Earth to study beach structure and tide charts to plan his approach. Both agree on one thing: the fish don't just happen.
"Effort is rewarded. And when you talk to people that maybe get a couple of decent fish in a season, it's like — how much are you fishing?" — Ian
Ian fishes every night during the season. Not most nights. Every night. Sometimes six hours, sometimes fishing from three hours after work until four hours before his next shift.
"If you're saying, 'Well, they just don't jump on my lure' — they don't jump on any of our lures. It's a matter of, are you going fishing twice a week for maybe three hours and going to the same spots at the same times and expecting a different result?" — Ian
Feeding Windows and Patterns [12:33]
This section produced some of the most valuable discussion of the entire seminar.
What Is a Feeding Window?
Calvin defines a feeding window as the specific portion of a tide when large stripers are actively feeding. Big bass are always in the vicinity — but they don't feed constantly.
"A lot of times in certain spots, that's around slack water when big fish will come out to feed — because they don't have the pressure of that water movement to fight against. And they also have bait that has been disoriented throughout the tide... now easy pickings for these large fish."
But every spot is different. In some locations the window is at slack water. In others it's at the height of the tide, when current funnels bait through a narrow area. The only way to know is to fish the same spot through complete tide cycles, under all conditions, many times over.
What Is a Pattern?
Ian makes an important distinction between a lucky night and a genuine pattern:
"Patterns are something you didn't luck out on. This is not a one-time thing. This has been a reoccurring occurrence 30 times or more because you put in the time. It's not like a one night, 'oh, that worked really well.' This is like — in a two-hour window with the tide, three hours from the drop, every night for two months."
A pattern is repeatable, predictable, and built on accumulated time at the same spot under consistent conditions.
Calvin's Six-Night Example [09:11]
Calvin shared a story that illustrates patience and persistence as well as anything:
During early May last year, he identified a boulder field spot he believed would hold big fish. He took a full week off from work and fished the same spot for six consecutive nights.
For five nights: one fish.
On the sixth night, during a 30-minute window, he took quality fish consistently.
That window — 30 minutes out of six nights of fishing — was the payoff for understanding the spot deeply enough to know when it would produce.
Spot-Hopping Strategy [14:39]
Ian and Calvin approach mobility differently, and both strategies are worth understanding.
Ian: Micro Skips Across Multiple Beaches
Ian rarely commits to one beach for an entire night. Instead he uses what he calls "micro skips" — moving between beaches that are close enough to be walkable, but where driving is smarter.
His typical night might cover four beaches in one tide, provided he starts early enough:
- Arrive before the fish do — beat them to the spot
- Give each location 40 minutes before moving if nothing is happening
- Pick a direction and commit to it (start in Truro, move toward Wellfleet — don't backtrack)
- Prioritize the drop tide, fishing dead low rather than high tide on the outer beaches
"If you show up when it's going to be good, by the time that beach hasn't worked out and you've got to move, now it's dead low — or even worse, dead high."
The logic: cover enough ground that you intersect with at least one spot during its productive window in a given night.
Calvin: Sitting on a Known Window
Calvin's approach is nearly the opposite. Because boulder fields are more structurally consistent year to year, he can identify a specific window with confidence — and then simply wait for the fish to show up.
"Whether the fish shows up that night or the next night or a week from now, I just adapt my timeframe to meet that window of the tide and those conditions."
He'll fish the same spot, during the same tidal window, for six nights in a row if that's what it takes — because he trusts the pattern he's built through years of experience on that structure.
Plug Selection [11:09]
Both Calvin and Ian take a disciplined, pre-planned approach to plug selection — not a trial-and-error rotation on the water.
Calvin's Method
Because Calvin wetsuits and skishes into boulder fields, he travels light:
- A single tube bag or two-tube bag
- A bucktail pouch
That's often it. The decision about what to bring is made before he leaves, based on:
- What bait is currently present
- Current and wind conditions for that night
- What the spot requires under those specific conditions
"One spot can require a completely different rotation of plugs depending on whether you have the wind to your back or the wind in your face."
His go-to confidence baits for big fish:
- Tubes and bucktails matched to resident bait
- Live eels — "They take more fish than just about anything"
Once his patterns are established, he sticks to a very small rotation of plugs, jigs, and plastics that he knows are proven on that structure.
Ian's Method
Ian's plug selection follows the same principle — know your bait, know your conditions, make the call before you leave. His approach to covering multiple beaches in a night requires being efficient on the water rather than experimenting with a large plug bag.
Key Takeaways
The through-line across everything Ian and Calvin shared comes down to a few core principles:
1. Preparation happens off the water.Scouting at low tide, studying Google Earth, snorkeling the bottom — the most important work is done before you ever pick up a rod.
2. Know your environment.Boulder fields demand an understanding of resident bait and consistent structure. Sandy beaches demand constant scouting because nothing stays the same.
3. Build real patterns, not lucky nights.A feeding window only becomes a pattern when you've confirmed it over many tides, in many conditions, across multiple seasons.
4. Commit to the work.Ian fishes every night. Calvin spent a week on one spot for a 30-minute payoff. Trophy fish don't come to casual anglers.
5. Fish with purpose.Whether you're covering four beaches in a night or sitting on one window for six nights straight, know why you're doing what you're doing — and do it with intention.
