A++++ Afternoon fishing trip; Will absolutely go again

Went on Captain Mark’s boat on a whim on a mild June afternoon— was absolutely and positively NOT disappointed. Mark took us to some bluefish and striper spots where we had our first catch within 30 seconds of our first cast. All in over the 2.5 hour trip, we caught near 20 fish between the two of us and had them all cleaned, filleted, and ready to eat by Mark and his first mate upon our return to the wharf. Can you say bluefish pate? Yummmmm. All in, an amazing time and our first of many trips with Captain Mark. If you’re on the fence, DO IT! You will not be disappointed and will consider your 2.5 hours well spent.



Excellent Again!

What a great Fathers Day 2018 treat. Fishing with my daughters and catching many may fish. Beautiful day, great boat, great crew. Educational, peaceful in Nantucket waters and fun all in one. Captain Marc and his crew were excellent. Always teaching and always being sure everyone catches. We are looking forward to our dinner tonight of fresh caught fillets. Thank you for another great experience.

Just do it.....

Always a great time with Marc and crew. He always seems to find the fish and you learn something new each time. He has been on the water now 30 plus years and has seen a lot. On this rather calm day we fished the slick around great point and caught some huge blues!! Crew kept everyone on it and going the entire time.
