G'day gonebush. You have me thinking about getting one, would you recommend something about 180L or bigger? Something to take the kids around the harbour or lake would be good too
Depends how much you and your kids weigh. I've got a three year old and reckon I could paddle her around on a lake and I weigh about 83 kg. assuming you're about the same, somewhere between 160 and 180L is probably the go. 160L feels like a bit of a boat once you're on a wave but I'd be on a surfboard if it was bigger than 3 ft or punchy anyway.
A competent sup rider my weight could probably get away with 110L or less but that kind of defeats the benefits of a sup in small waves to my mind.
