“Ma Sheila” is a custom 1993 Billy Knowles 37’ Walkaround refit in 2019. “Ma Sheila” comes equipped with a Seakeeper and is considered by many to be one of the finest mid-sized walkaround fishing boats ever built. This Knowles 35’ completed an initial refit in 2015 including Cummins factory reconditioned QSB 380 HP engines with electronic controls. In order to make her a light tackle world record chasing machine, “Ma Sheila” had a complete bow to stern refit in 2019 including a Vetus bow thruster. The walkaround combined with the 488 ft./lbs torque bow thruster will spin this 1993 Billy Knowles 37’ in a 360-degree circle in seconds, making it almost impossible for a fish to get away!

After graduating college with a maritime degree, Scott Levin spent the next 25 years sport fishing around the world. From capturing and tagging numerous blue and black marlin and tuna over 1000 pounds, to many world-record catches and tournament wins, Scott’s had experiences that most people can only dream about. He’s been fishing in most regions of the world, with many of the industry’s top sportfishing captains. He currently holds an All-Oceans 500-1600 Ton Masters Coast Guard license.

Scott has extensive experience building many sportfishing boats, as well as being an instrumental part in the planning, designing, and building of a custom 160' expedition mother ship yacht capable of carrying and launching a sportfishing boat in under two minutes.

He’s lived aboard many mother ship/sportfishing operations and operated sportfishing boats and yachts up to 160’ throughout the East Coast of the US, Gulf of Mexico, Bahamas, Hawaii, Australia, Madeira, St. Thomas, Mexico, Bermuda, Cape Town, Canary Islands, Cape Verde, Ascension Island, Costa Rica, Cabo San Lucas, and Tahiti. He’s also navigated the Pacific, including a Trans-Pacific Ocean crossing, the Atlantic Ocean, Caribbean, and Coral Sea.

Scott believes in continued service after a sale and always looks forward to walking clients through the process, from finding them the right boat, to setting them up to experience their dream of fishing, diving, or just exploring the world.
