The Karnic SL 652 continues the approach of maximising every inch of space to create a boat that combines socialising and comfort, with the added advantage of a closed forward cabin. With a length of 6.3 metres (7.15 metres including the bathing platform), this model offers the possibility of sleeping on board, making it ideal for those seeking longer getaways or the convenience of being able to rest during their time at sea.

Unlike the SL 651, which has an open bow, the SL 652 features a forward Sundeck design, allowing for a spacious and comfortable sunbathing area while also providing the option of using the cabin to rest or stay overnight. This additional space adds a level of versatility that makes the SL 652 a perfect choice for those wishing to enjoy both days and nights on the water.

The centre console design still allows for wide side passages from stern to bow, facilitating movement and encouraging interaction among passengers. The aft, as in other models, offers a straight sofa for cruising, which can be transformed into a U-shaped sofa around the table for dining, and finally into a large sunbed. All of this is complemented by a bimini top that provides shade and protection during the day.
