The Galaxy SW345PN suits owners of inflatables and small RIBs who want the lightest trailer that still meets EU type approval, since its 500kg gross weight lets many small cars tow it without extra licence categories. Its multi-roller bed is built for a soft or RIB hull rather than a hard-chine motorboat.
