Hi guys, new here. So about 8 years ago my parents bought me my first surfboard made by "exp...". It's 6ft 3 x 18.4in x 2.5in. I've had about 10 lessons and am quite capable on a softboard . I'm 19 years old, quite tall at 6ft 5 and weigh around 75kg and am a very capable swimmer if that helps. I know this board is far from ideal for a beginner like me, But my question is will i be able to learn on this board, even if it takes a lot more time than a longboard? Or will it be near impossible?
Just to add I've lived in London for my whole life and only recently moved out to Brisbane and surfing has always appealed to me so want to give it a try!

Cheers!
