Worth knowing

Stefini Yacht Design; cover, cost and conditions

Under the name Stefini Yacht Design our model records hold a compact, closed range of motor yachts and one sailing yacht. Its core is the Erreline K series, large motor yachts whose three digit number roughly gives the length in decimetres: the Erreline K 145 is 14.4 metres long, the K 165 16.7 metres. Two smaller lines with their own names sit alongside, the Harpoon 255 as an open boat and as a WA version, and the Tempest 330. Only one model carries the Stefini name itself, the sailing yacht Stefini 13.50.

We list nine models, eight motor yachts and one sailing yacht, all recorded with the same build years from 2003 to 2012. The Erreline K series has five: K 32 at 10.4 metres, K 128 at 12.85, K 145 at 14.4, K 155 at 15.65 and K 165 at 16.7 metres. The Harpoon 255 comes as Open and WA, both 8.4 metres, the Tempest 330 measures 9.9 metres and the Stefini 13.50 13.9 metres. Lengths therefore run from 8.4 metres (Harpoon 255) to 16.7 metres (Erreline K 165), with three models under ten metres and six above.

The 8.4 metre Harpoon is the one boat in the range that fits on a road trailer and can be launched at a ramp. The Erreline yachts from 10.4 metres stay on a marina berth and are lifted out by crane for the winter. With every model dating from 2003 to 2012, a look at engine service records and later upgrades says more about a boat than its brochure.

What this means for the cover

For the Erreline K 32, Erreline K 128,

Erreline K 145 by Stefini Yacht Design and 6 more series the market value and the replacement cost

often differ widely.

An agreed value removes the age-based scale, and the figure in the policy stands.

For the Erreline K 32, Erreline K 128, Erreline K 145 by Stefini Yacht Design and further series:

On motor yachts the drive and the electronics together make up about half the value.

Both belong in the valuation, otherwise the sum insured is too low.

For the Stefini 13.50 by Stefini Yacht Design series:

On sailing yachts the rig and the underwater hull are the expensive parts:

a dismasting quickly costs a quarter of the boat,

and osmosis counts as wear and is covered by no hull policy.
