Playing from the gold tees, Marels, 31, from Dartmouth, made light of the 7,156-yard lay-out to card six birdies in his record-breaking performance to beat the previous best score by a single shot.
The one-handicapper recovered from the setback of bogeying the first hole to reach the turn in two-under par and another three birdies on the back nine secured his place in the record books – despite a double bogey at the par-four 14th hole.
He said: “It felt like a normal day, especially after the opening hole, but the important thing was that I didn’t let my head drop as I’ve learned over the years that many good rounds start with a bogey.
“I double bogeyed the 14th hole and had a hole in my stomach as I walked off the green but I recovered well and knew on the 18th tee what I had to do.
“It feels great to hold the course record as Dartmouth’s a really tough course off the back tees, and it felt really good to hear your friends talking about your round in the bar afterwards.”
Marels, who played for Devon’s men’s second team in 2012, made the worst possible start after his opening tee shot bounced under a hedge but he responded in style with birdies at the second, fourth and ninth holes.
After picking up another stroke at the 13th after holing a 30-foot putt, disaster loomed for the crab fisherman at the next hole when an ugly double bogey six put his record attempt in doubt.
But Marels quickly recovered to immediately get a shot back at the 15th hole – the hardest hole on the course – and another birdie at the penultimate hole left him needing a par at the 238-yard par-three 18th to claim the record.
Situated in 225 acres of south Devon countryside, just outside the beautiful town of Dartmouth, Dartmouth Golf & Country Club boasts 27 holes, with the 18-hole Championship Course and Dartmouth Course complementing each other nicely.
The Championship Course was designed to challenge the most proficient golfer, with strategic positioning of tees, meandering streams, 12 water features and undulating greens. But while it makes the better players think, it is not so punitive as to spoil a round for high-handicappers and provides an excellent and enjoyable challenge to golfers of all abilities.
Although only a nine-hole layout, the Dartmouth is built to the same high standards as its sister course. Measuring 2,252 yards with a par of 33, it is guaranteed to test players while they enjoy a more relaxed round.
In addition to golf, the resort also boasts first-class leisure facilities, which include an indoor pool, Jacuzzi, sauna and spa.
There is also plenty to explore in the surrounding South Devon countryside and along the coast. Located just four miles outside the historic town of Dartmouth the resort is an ideal base from which to visit the area’s many beaches and attractions.
