About this tender
Williams SOLAS 625 - what we know.
The Williams SOLAS 625 is a 6.3m solas tender from Williams, built in Oxfordshire, UK: single 230hp jet, 40 knots and 11 guests.
The Williams SOLAS 625 is the build we ask Williams Jet Tenders for when a programme demands full SOLAS certification without sacrificing the handling qualities that make a jet tender worth operating day to day. At 6.32m on the waterline, it carries eleven persons and fits comfortably aboard yachts of 40 metres and above. The 230hp Yanmar 4LV diesel drives a jet pump rather than exposed propeller hardware, which matters operationally when you are working crowded swim platforms or rocky landing stages.
The SOLAS specification here is not a sticker on a standard hull. Williams has engineered the 625 with fire-retardant resin and gel coat, SOLAS-specification tubes with lifeline, a manually activated righting system, capsize-protected fuel system, emergency manual tiller arm, and the full complement of SOLAS rescue equipment. A hi-visibility cover with retro-reflective tape replaces the bimini options you would see on the DieselJet 625 range - capsize and man-riding regulations make that a non-negotiable trade. If your safety management plan requires a vessel that a flag state inspector will pass without question, this is the specification to quote.
On the navigation side, Williams fits a Raymarine Axiom 7-inch MFD with depth sounder and chartplotter as standard, alongside a helm-mounted type-approved magnetic compass, VHF radio, and position indicator light. The helm console folds for low-profile stowage, dropping overall height from 1.60m to 1.29m, which matters when your tender garage has a tight clearance. FlexiTeek decking, leg bolsters, and stainless steel grab handles round out a build that we would put alongside the better European SOLAS tender offerings without hesitation.
