Telescoping beams work but it is hard to say that they are user friendly. I was always finding excuses not to trailer the SC21 because I disliked the system so much. It jams easily with sand, the bolts were difficult to remove, parts got lost...

The reason I favor some kind of swinging beam system is that it could also be used in the water. Maybe somehting like the X folding beams shown in the last MM, page 20 (Cat 2 Fold). It doesn't need to lower the mast to fold.
