The boat is delimited around its perimeter by a float closed upon itself and comprising at least two superposed floating fender sections. The lower fender section is longer than the upper fender section and extends locally beyond the upper fender section towards the outside. The projecting region delimited by the lower fender section beyond the upper fender section is covered by a covering fixed to the projecting portion of the lower fender section and to that part of the upper fender section bordering this projecting region. Thus, the boat is provided with a projecting zone forming a low platform area onto which a person in the water can raise himself or herself in order to get into the boat more easily.
