The Sanlorenzo 500Exp: Built for the Owners Who Actually Go

If your plan involves remote water and months rather than weeks, the Explorer line is the part of the Sanlorenzo range built for it. The yard describes it as born of a vision to give the most adventurous owners the freedom to reach the world's most remote waters — remarkable range and capability, with the refinement and ease of a true Sanlorenzo.
What distinguishes the 500Exp from a motor yacht wearing explorer styling is that Sanlorenzo built it on a purpose-made platform, with a reinforced hull and systems chosen for durability and stability in varied conditions. The 65,000-litre fuel capacity on a 154-foot hull is the clearest evidence of intent.
The Explorer line has exactly one model at Sanlorenzo, and this hub covers it — the line is the boat.

500Exp — 154'2", under 500 GT, 15 knots, 10 guests / 9 crew. Twin CAT C32 ACERT diesels and 65,000 litres of fuel: the largest tankage-to-length ratio in the Sanlorenzo fleet, and the reason this boat can go where it claims to.
Sanlorenzo keeps the 500Exp deliberately under 500 gross tons, which has real consequences for survey and manning obligations depending on flag and use — and is very likely why the design sits exactly where it does.

The 500Exp is one of a small number of yachts in this size range that was drawn as an explorer from the keel up rather than restyled into one. You can see it in the fuel capacity: 65,000 litres on 154 feet is not a motor yacht's tankage.
Range is the number to establish properly rather than take from a listing, and an explorer buyer of all people should insist on working it from figures whose origin they can name. Take observed consumption from a sea trial at the speed you intend to hold, divide the published 65,000 litres by it, keep a serious reserve, and you will have a range you can defend to your insurer and to yourself. Then ask about redundancy — generators, steering, watermakers — because an explorer's real specification is its spares list, not its top speed.

Work it from the published tankage: 65,000 litres of fuel on a 154-foot hull, the largest tankage-to-length ratio in the Sanlorenzo fleet. Take observed consumption from a sea trial at the speed you intend to hold, divide the capacity by it, and keep a serious reserve — that produces a distance whose origin you can name, which is what ocean-passage planning deserves. The published maximum is 15 knots, on twin CAT C32 ACERT diesels.
