The trailer length does not depend on the boat length but on its dimension, which is the dimension between the transom and the chain plate ring. The theoretical length thus obtained can be adjusted as required up to without impacting the compatibility of the trailer with the boat. It is possible for some brands to add a storage box to the winch support stand (finishing). In this case, the theoretical length of the trailer will be longer (see Table below). To determine the optimum length of your trailer, it is necessary to measure the length X of your boat and add a fixed dimension according to the Table below. It is a minimum theoretical length from which you can select one of our models. Each trailer GVW is provided in lengths (multiple of). It is possible that, in specific cases, the boat theoretical length is not available for the required payload. In this case, it is necessary to select the next higher GVW.
The dimension X must be measured from the boat part resting on the rollers (some boats have a "chaise" - offset hull portion which does not rest on the trailer rollers). The theoretical length is provided for a trailer configuration with a winch support previously defined for the boat (according to the Table below) and whose bow stop, in raised position, is under the chain plate ring (at cm).
The only function of the winch stand is to support the winch and ensure an optimum pulling line which, associated with the launching system, will facilitate effortless boat handling. The bow stop helps to stop the boat when it is lifted, but is under no circumstances a tie-down point, nor a safety making it possible to stop the boat in the event of sudden braking or collision. A different tie-down compliant with the legislation must be used. It is important to get the best winching that the bow stop is positioned under the chain plate ring and that the winch is positioned slightly below the level of the chain plate ring so that the strap forms an upwards angle, or is at least horizontal when the boat is in contact with the bow stop. For semi-rigid hulls, the stand is thus most often positioned under the hull and not in front of the boat. Our winch supports come in several models and configurations to optimally fit all boat types. To find a suitable stand, several parameters must be taken into account:
Each Nautilus, Rocca and Satellite trailer is fitted with a stand defined to fit, on average, the majority of hulls in view of the trailer dimension. However, this is sometimes not optimum. This is why we offer, at no extra cost and on request, to fit your trailer, when you buy it, with the stand of your choice. You just have to specify it when you order from your authorised dealer.
We put at your disposal an assistant configurator to determine the QuickFlex system, if it is not pre-fitted on the trailer, or to determine the lassos corresponding to your boat. You can buy these products online.
