Over the weekend, my family and I, with our club, did a 23 mile paddle down the River Wye, just for two days. It wasn't that far but it was quite fun and relaxing. I was in a boat, mostly, with my Mum and while paddling we started joking about all of the different boats that kayakers/ canoeists need. So here in the incomplete (and most likely inaccurate) list of boats required by every paddler!
(This is a complete joke and I doubt anyone actually has all of the following boats. Although, wouldn't it be the dream!)
That's all I can think of right now. I'm sure that some of those cross over but I don't know a lot about them. For example, I'm not sure how similar a boat you use for slalom and wild water racing because I don't know a lot about them. I also didn't include anything about sea racing besides the sea kayak. This is mostly because I know nothing about racing in kayaks or canoes.
Anyways, so once you've got all of the needed kayaks, you just need to find somewhere to keep them!
Good luck xx
