Pro-Line 3310 Review

With the 3310, Pro-line has taken its reputation for quality to a new level.

October 26, 2001

Despite slow fishing on the day we ran Pro-Line’s new 3310 Express, I’m glad I went. The outing gave me the chance to offer congratulations to Pro-Line. The company has made longer boats, but never a bigger, more dedicated fishing boat. The 3310 elevates them into a new genre, where they compete big offshore boats.

Winds came out of the southeast at 10 mph, pushing some ugly, very closely spaced 2- to 3-foot seas. It wasn’t rough, but it was uncomfortably messy. The boat handled the headsea admirably. Head-on at 25 mph, the 3310 knocked the spray outward just forward of the windshield.
With full fuel and water and five passengers, optimum cruising speed with twin Yanmar 350-hp diesels turned out to be 33 mph at 3,400 rpm, burning 18 gph or 1.8 mpg. At this speed, you can expect a range of 498 miles. Top speed of 37 mph at 3,950 rpm bumps fuel consumption up dramatically to 32 gph or 1.2 mpg. You lose almost 200 miles of range at that speed.
It took about 16 seconds to plane. Fortunately, Pro-Line plans to offer the new ZF two-speed gear box as an option, which will cut the time to plane down to less than five seconds. It’ll also make live-bait trolling easier, canceling the need to shift in and out of gear.
After running bigger boats, you forget just how agile a twin-screw package this size can be. The only thing that would make close-quarters handling easier on the 3310 would be optional single-lever controls. Whether facing aft following a fish or backing into a slip, it’s much easier to have a single throttle/gear control on each side of your body than two throttles on one side and two gears on the other.
You’ll definitely notice the quiet ride on the 3310. Side exhausts combined with excellent engine-room insulation make a synchronizer almost a necessary option when running from the tower.

I purposely backed down hard and fast to bring water over the transom, and it proved no easy feat. The 3310 wants to bolt back like a frisky colt. When I finally got a wave to break over the transom, I put it in forward to see how long it would take to drain. By the time the turbo boost kicked in, the cockpit was empty, thanks to some of the biggest scuppers in the business.
The 3310 offers average roll stability in a beam sea while leaving a very clean wake at slow trolling speed. Every aspect of design for fishing has been well-planned, from the height of the cockpit gunwale above the water to where the rail hit me just above the knees. From the great handholds and easy walk-around to the bow to the space provided for four anglers to fight a quad of sailfish without shoving one another out of the way, this boat immediately enters the ranks of classic 31- to 35-foot sport-fishing machines. The comfortable tower station includes great seating and leaning positions. Pro-Line has designed a clever, quick-flip-down seat arrangement to afford an unobstructed view aft without sacrificing any comfort. You’ll find no under-gunwale rod storage but plenty of room belowdecks under the settee as well as five rocket launchers across the hardtop and four rod holders in the gunwales.


There’s no shortage of storage space aboard the newest Pro-Line, with transom and in-deck fish boxes, both fitted with pumps and macerators. The helm-deck seat pods provide space
for the optional refrigerated cooler on the back side of the helm seat and a
rigging station with sink and large livewell behind the passenger seat.
Below, space has been used wisely, with a double V-berth forward that will sleep two and an L-shaped settee amidships to starboard to sleep another two in individual bunks. To port, you’ll find a full head with shower and a galley with stove, built-in microwave and coffee maker, reefer and sink. High-gloss cabinetry with push-button locking latches and optional teak and holly sole elevate the interior to luxury status. Pro-Line also answers one of my pet peeves on sport-fishing boats by providing good ventilation belowdecks, thanks to two overhead-opening hatches.
The new generation of Yanmar engines does a great job of putting a lot of horsepower into a footprint much smaller than its competitors. The 350-hp Yanmar diesels leave plenty of working space in the engine room for routine maintenance. The plumbing and wiring have been very well laid out and executed; all the 110 Vac wiring goes through the port side of the compartment while all the 12 Vdc travels likewise down the starboard side. Pro-Line serves as an example for other offshore builders by using only soldered connections covered in heat-shrink tubing aboard the 3310.
Pro-Line bumped up the construction quality on this boat as well, using only the best knitted fiberglass and vinylester resin with custom-blended gel-coats containing titanium dioxide as a very effective ultraviolet prohibitor.
