Our trailer listings include three specs. "Bow Eye to Transom Minimum", "Bow Eye to Transom Maximum", and Boat Hull Size Minimum and Maximum. The information offered under should make it easier to higher approximate how your boat will sit on a trailer.  
The diagrams display the correlation between the boat hull and trailer dimensions.  
If you happen to would like to look up boat's dimensions or weight click on here.  
The Bow Eye to Transom measurement as proven in the accompanying diagrams is the most critical in sizing a trailer for boat length. Pulpits and Euro transoms are usually not supported by the trailer. Including these in length measurements might end in a trailer that doesn't fit nicely nonetheless they nonetheless have to be a consideration when choosing a boat trailer.  
These trailer schematics are supplied for boat hardware instance the dimensions displayed on most of the product charts that follow. Most of our boat trailers have a large amount of adjustment within the help construction. Adjustment to both extreme might require shifting the axles to keep up tongue weight within the 5% to 7% supreme vary for many trailers. Schematics are a visual representation of a generic trailer. Not drawn to a specific scale.

Other Important Considerations WHEN FITTING A ship TRAILER  
Transducers:  
In case your boat has via-hull or transom mount transducers you should remember to place trailer bunks so they do not come into contact with transducers. In some uncommon cases, transducers have to be moved to allow a ship trailer to suit correctly if not the transducer and the trailer will probably be damaged.  
Bow Pulpit:  
A bow pulpit us often a narrow platform that extends ahead from the entrance of the boat. It can be purposeful or cosmetic. Pulpits often present assist and extension to an anchor davit that helps the anchor on the end of the pulpit. When a ship has a pulpit, the way the hull is supported whereas the boat is loaded and unloaded is important. If a hull drops off the trailer while sliding in the water too early the pulpit might hit the winch stand. Bow information boards are a common resolution.  
Motor Bracket:  
Motor brackets are metallic or fiberglass bins that enable the mounting of outboard motors behind the boat’s transom. Brackets will increase the quantity of weight on the rear of a trailer. Are not counted when measuring the length of the hull. Axle position might need to be moved towards the rear to achieve correct tongue weight of 5% to 7% of the total boat’s weight.  
Inboard Engine:  
There are 2 varieties of inboard engine configurations that concern trailer match. One is a straight shaft. The other is a V drive. The straight shaft locations the engine extra towards the entrance. The axle place on the trailer might need to be moved ahead as properly to realize proper tongue weight. Secondly, extra clearance is required for the shaft to clear the trailer frame. Most shaft drive boats as much as 24 ft will match on our standard aluminum trailers. A V drive is a consideration solely in that the rear of the trailer must be robust sufficient to help the additional weight of the engine within the rear. The load is similar to a stern drive engine configuration.  
New Volvo Forward Facing Drive:  
Your boat would require special fitting. Please contact us for extra info at 888 278-1991.  
Trim Tabs:  
Trim tabs should not impact trailering generally. Always retract your tabs previous to loading your trailer.  
TOW Vehicle Requirements  
Please check with tow automobile capabilities supplied by the producer and evaluate with trailer necessities.  
- Towing capability: a tow car have to be rated for the full GVWR of the trailer being towed.  
- Hitch: a hitch meeting rated must be rated for the complete GVWR of the trailer being towed.  
- Tow ball measurement: match tow ball to the coupler / actuator requirement (2" or 2-5/16") relying upon trailer capability.  
- Tow ball peak: 18" to 21" from the ball centerline to the ground. Adjust through the use of an offset drawbar.  
- Trailer electrical connection: Four or 5 pin flat pigtail connector if no brakes or surge brake equipped, and 7 pin spherical if Electric Over Hydraulic (EOH) brake outfitted.  
To calculate needed trailer capability, calculate the overall weight together with the boat, the engine, a full gasoline tank (approximately 7 lbs. per gallon), full water tanks (if applicable) and your personal gear. An excellent rule of thumb is to make use of 10% of boat, motor, and liquid weights for private gear. Select a trailer with the next highest capacity rating. When you intend to hold extra gear or luggage within the boat over long distances, consider the weight of these items, too.  
boat weight + engine weight + ((fuel capability x 7 lb / gal)+  
(water capability x eight lb / gal) = Total  
Then multiply Total X 1.1  
= Trailer Capacity Needed  
- Brake controller: required on models with electric or Electric Over Hydraulic (EOH) braking methods  
TRAILER LOAD-CARRYING Capacity  
To find out the load capability requirement of your tow vehicle, confer with the Vehicle Identification Label attached to the trailer on the left body rail just behind the tongue junction. It is going to show the maximum load-carrying capacity of the trailer. It is required to point out the Gross Vehicle Weight Rating (GVWR) which is the load-carrying capability plus the burden of the trailer itself. It is the trailer operator’s responsibility to make sure that the total weight of the boat, engine gas, water, gear and trailer don't exceed the GVWR capability.  
If you do not know the proper weight of your boat and engine, don't guess; have it weighed. This normally could be performed at an area lumber yard, feed and fertilizer retailer, quarry, truck weigh station, and so on. If you have any sort of questions relating to where and the best ways to use boat parts shop, you can call us at our own internet site. Take the overall weight of the rig. Subtract the trailer dry weight that is famous on the VIN sticker.  
Be particularly careful to not overload the trailer by placing heavy gadgets, camping gear, and so on., in the boat while travelling. If you should carry such gear in your boat whereas trailering, take this into consideration at the time of purchase and go to the subsequent bigger-dimension/capacity trailer.
