I did 8 hours into a headwind on Loch Ness in April. With correct technique it’s not too difficult if it’s windy.Forget about 2 adults on a paddleboard it will be a PIA.
I ended up with one by accident bought it for my daughter as a birthday present but unknown to me here hubby got her one so I kept it for myself.
If is good fun but limited by conditions, if it's windy you often go backwards and have to kneel down to paddle back against the wind. Only useable on rivers with very slow currents unless there is someone to transport you back.
Only used mine once at home this year as its been too windy all year.
My £300 Amazon Goosewing job is as good as daughter's £400 Two Bare Feet but hers looks posher. A friend has £800 one and he reckons mine is better on the sea. I think it's pot luck with the cheap ones.
I have a two wheel trolly I strap it to, for getting down the beach 200yds as the crow fly but 500 yds around the road & of course an electric pump.
grasscutter & his other half Paddleboarder are into quite serious paddleboarding.
I’m leading an open water course this weekend in the Lakes covering paddling in wind.
