South Point Bonga Perkins MK2 Longboard 9"1
For $600 usd. On most website online I see that it goes up to $900. It is brand new and have never been in water. It has 2 scratches due to transporting it around. Comes with FCS EZI fin. Not like I have got any clue whether it is a good deal or not. Reading from their website, it is suitable for intermediate but I'm still a beginner, as can be seen from my previous post that I do experience quite a lot of perling.
My height is 172cm and 62kg. I'll only be surfing at a sandy beach and they said during the summer the waves will gradually decrease in size. It won't be much higher than waist. I got pictures of the area that I'll be surfing it it helps to choose the right board.
I don't have a board at the moment and I've been renting it all the time. I've rented at least more than a dozen times and with that money I could've bought myself a board. Cost $16 to rent each day here.
I asked one of the shop owner and he said because I go at least 2-3 times a week, I should perhaps purchase a shortboard more suitable for a beginner. Like a 6"3 Torq board http://www.torq-surfboards.com/fish-63.html He said I will struggle for a long time but he would advise that I go for that board as it is sturdy and tough so it won't break that easily. In addition, the 6"3 board will allow me to fit it into the car so I don't have to install a roof rack.
