The function as a life-saving vessel is based on the concept that depending on where you are, when a leisure craft is abandoned, there is no absolute assurance of rescue, even if an EPIRB is activated. Being capable of sailing even in bad weather conditions, this dinghy is able to take two persons towards the closest land, provided no beating against the wind is required.The Caravela 1.7 with its shorter sail plan may be considered a life-saving vessel for the following reasons:1 - The three water-tight compartments have a total volume of 390 litres, which allow up to two persons to be carried with positive flotation, with a reasonable safety margin.2 - Two of these compartments have inspection ports (deck plates) which allow for dry storage of personal belongings and emergency equipment.3 - The cover that we recommend to be made to protect the hull when it's lying on deck upside-down, when inverted and with its hem lashed under the rubbing-strake, makes a canopy that provides shade and protects the crew from the elements. 4 - Unobstructed cockpit (yes, this dinghy has a watertight cockpit, even though it is self-draining only when the dinghy is not on service, bliss when it pours heavy rains at night, the water draining by scuppers, not requiring to be bailed by hand on these occasions. You only must remember to shut the scuppers before boarding the dingy) which allows one person to get some rest at a reasonably comfortable position.5 - A reduced sail plan and a rig that can be installed by one person unassisted, even if the dinghy is drifting away from the mother boat.6 - The watertight fore-castle allows that one person at a time can climb onboard, with no need of external help. The first person that climbs aboard takes the aft seat to balance the trim for the second one to come aboard.Some equipment may enhance the chances of survival, like portable GPS and VHF, as well as a hand operated desalinator. Even though the dinghy Caravela 1.7 may serve as a life-saving craft, it should not be considered as so in substitution of the country’s mandatory life-saving equipment. There is no restriction in any legislation that you have a complementary means to cope with the emergency of a shipwreckOne of the great advantages of building the dinghy Caravela 1.7, if you intend to be involved with a more radical challenge of building your own cruising sailboat, is the opportunity to improve your skills as an amateur builder gathering experience with an easy to build, affordable craft.Main DimensionsLenght Overall:1.70 mMaximum beam:1.24 mMaximum height:0.48 mWeight (empty):35 kgDisplacement (two persons):200 kg (aprox.)Reserve buoyancy:390 litresSail area (leisure):2.43 m2Sail area (unofficial survival craft):1.43 m2
