The 30-year-old from Kells, County Meath, admits he was "gutted" to finish the first stage of the iconic solo race in 12th place in the 56-strong 'série' division for production boats.
One of the pre-race favourites after a strong 2017 season, Dolan led the fleet out of La Rochelle, France, until realising he had made a course error and had to turn back.
The mistake relegated him to the back of the fleet but he managed to fight his way back to finish Leg 1 in Las Palmas, Gran Canaria, just outside the top ten after just shy of 11 days at sea.
Tired and frustrated by the result, Dolan flew home to Ireland to rest and recharge at his parents' house.
With the start of the second stage - a 2,700 nautical mile race across the Atlantic to Le Marin in Martinique - looming, Dolan said he is ready to put leg one behind him and pull out all the stops for leg two.
“It was heartbreaking having to sail back under spinnaker towards La Rochelle when I realised I'd made a mistake a few hours after the start of leg one,” he said.
“I managed to claw my back back to twelfth but it wasn't the result I was after. I was gutted.
“I decided to go home for a bit to rest up. It was my first week off in months and it did me well.
“Now I'm looking forward to getting going again. The run-up to the start of leg one in La Rochelle were stressful but going into the second leg will be much easier without so many commitments. It'll be nice to concentrate solely on the sailing.”
Despite Dolan's disappointment his goal of a podium finish is still very much doable – the Mini Transat is scored on cumulative time, and he is currently just seven hours behind leg one winner Valentin Gautier.
Unlike in the first leg where the fleet sailed a fairly straight line south west to Las Palmas, the second stage across the Atlantic will provide plenty more tactical options.
“I need to make up seven hours on first place and five hours on second - it's nothing really over a 2,700-mile leg,” Dolan said.
“Because the next stage is across the Atlantic there will be much bigger lateral splits between boats. Anything can happen. One wind shift of a few degrees could see that time wiped off.”
The forecast for the start of leg two, beginning on Wednesday, is for stable North Easterly winds of 12-14 knots – perfect conditions to propel the fleet out into the Atlantic.
The stage is expected to take around two weeks to complete.
