Ledit élévateur comporte au moins un bras de bossoir (20) pivotant dans un plan vertical et comprenant deux bielles (21a, 21b) respectivement montées pivotantes côté cage (10) sur un palier supérieur et un palier inférieur à axe horizontal disposés sur un poteau sensiblement vertical solidaire de la cage, et côté ber (10) sur un palier supérieur et un palier inférieur à axe horizontal. Le ber peut être doté de propriétés de flottabilité. L'élévateur comporte en outre la commande (65) du dispositif motorisé de levage/mise à l'eau du ber entre une position extérieure immergée d'accostage/mise à l'eau, et une position intérieure surélevée maintenant l'embarcation (40) sensiblement droite entre le niveau de l'eau et celui du (34) pont (34) de la cage. L'élévateur (60) est conçu pour que le ber (10) portant l'embarcation (40) soit libre dans l'eau avant le levage.
