Captain Nick Kathmann
Captain Nick grew up chasing speckled trout and redfish in New Orleans before moving to Boston, and he's fished Massachusetts salt and fresh ever since, from the North Shore to the Islands. He holds a 200-ton USCG Master's license, is a certified sailing instructor, and has run major offshore yacht races and Safety at Sea courses.
Outdoor education is his thing: patient teaching, straight answers, and a genuine kick out of watching someone land their first striper on the fly. Bordering on insane, he'll fish year-round in the Northeast, even at −10°F.
A few from the boat. Every one of these is a real client, a real fish, a real day on the water.








"I had a terrific fishing trip with Boston Harbor guide Nick Kathmann. We found birds over schools of striped bass chasing minnows and caught fish all morning, at least 20 stripers, 32 to 40 inches. We carefully revived and released each one. Nick is a wonderful guide and I highly recommend booking a trip."
"It was my first fly fishing trip on a boat and I couldn't have found a better guide. Nick is super friendly and helpful. He helped improve my cast and we got some nice striped bass. I'm definitely coming back to him when I'm in Boston."
"Nick has been an impressive guide over the years. His vast knowledge of the game makes the experience enjoyable and informative. Patient, professional, and he knows where the fish are."
The best dates go early, especially the fall albie run. Send a quick note with your dates and what you're after. Captain Nick will get right back to you to lock it in.
Not at all. Trips are perfect for beginners through experts, and kids are always welcome. If you've never held a fly rod, we'll get you casting and hooked up. Plenty of anglers land their first striper on the fly with us.
No. Every angler aboard is covered under our commercial charter license, so there's nothing extra to buy, register, or bring. That's one less thing to worry about before your trip.
High-quality gear (high-end Daiwa inshore and Daiwa Saltiga offshore spinning setups, plus Scott/Hatch fly setups), custom-tied flies, tackle, bait, water and ice. Your fishing license is covered under our charter license, so there's nothing extra to buy. You're welcome to bring your own gear too.
Any food and drinks beyond water, non-spray sunblock, a brimmed hat, polarized sunglasses, a windbreaker or fleece (it's cooler on the water), rain gear, non-skid shoes, a camera, and seasickness medication if you need it. Kids under 13 must wear a Coast Guard-approved PFD at all times.
Trips usually start just before sunrise or shortly before sundown, adjusted for tides and weather. Captain Nick reaches out a day or two ahead to finalize the meeting spot near Boston or the Cape and the plan for the day.
Email Captain Nick or call or text with your preferred dates and what you'd like to target, or use the booking form above. Prime dates, especially the fall albie run, fill up fast, so reach out early.
