On a sea trip of 5 weeks in Sweden and Åland (Finland) Petra paddled a Sea Lion LV.
Aquarius of Poland sponsored her with a very light carbon/Kevlar kayak and we installed her Flat Earth sail to make our expedition more fun.
Petra picked the color scheme of her kayak and I thought the graphics were particularly attractive making the kayak very visible against the water and granite islands.
The kayak behaved very predictably in varied conditions and weather-cocked just enough to make it safe when windy, even in a storm.
The only real modification was removing the padding that was factory fitted on the seat; lowering the center of gravity made the kayak a bit more stable. Given that she has never paddled a Sea Lion LV before, Petra liked how she felt in that kayak right from the beginning.
Despite the cockpit maybe being a bit too roomy for her the key hole style thigh braces allowed her to brace efficiently when the waves picked up and tossed her around a bit.
Cargo space was sufficient for our extended trip and the main hatch covers (Kajak Sport) never leaked (the "glove box" needed a bit of sealing around the rim).
The skeg performed flawlessly and was butter smooth to operate. Adjusting the foot rests was possible even while paddling (without needing to exit the cockpit to reach the adjusting tab behind the foot rest!).
The shorter waterline and the rockered hull seems to be well suited to shallow waters with shorter waves (no ocean swell in the Baltic sea). Clapotis was not upsetting Petra and I noticed increased confidence in following seas where she was catching and surfing waves way faster than me, leaving me behind.
I think that the Sea Lion LV combined with a sail is a great fun kayak.
It performed well with just light loads in strong winds (slight leek cocking when sailing) and very steady when filled with camping gear, food and water.
