Worth knowing
STGi Marine; cover, cost and conditions
STGi Marine is listed in the data set with 8 catamarans of the Aventura line, half sailing and half power catamarans. Build years start in 2015 and continue into current production, with lengths from 10 to 14.9 m. Recorded models include the Aventura 34, 37, 44 and 45 under sail and the Aventura 10, 14 and 50 MY with engines.
Catamarans of this size call for a properly set value and a clearly named cruising area, since both determine the rating. With the recent build years from 2015, hull cover with a bindingly agreed value is the focus.
NAMMERT insures STGi Marine Aventura catamarans regardless of build year and place of purchase. The online calculator shows the premium in about 5 minutes.

As the series is still in production, parts are available and repair costs are predictable. Even so, value it at replacement cost including retrofitted electronics, not at list price.
On catamarans the bridgedeck between the hulls is the sensitive part, and the berth belongs in the application: double width often means a mooring rather than a marina.
For a series built in these years 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.
