Getting gold with an expert boat might be hard for some but with patience and practice you will get this eventually. I suggest doing the time trials under par time first to get used to the stages. Once your used to the stages i suggest using the boats - Razorback and Rad Hazard, when one doesnt suit you, use the other. Always try to get a boost start and look for all the shortcuts. If you can, try to stay in boost the whole time cause it can be hard at times to come first. good luck
