Topic: Sponson


  
  Sponson - Wikipedia, the free encyclopedia
Sponsons are projections from the sides of a watercraft, for protection, stability, or the mounting of equipment such as armaments or lifeboats, etc. They extend a hull dimension at or below the waterline and serve to increase floatation or add lift when underway.
Sponsons are commonly used on jetskis and other personal watercraft such as canoes to provide either additional buoyancy and thus stability against capsize, or hydrodynamic forces to resist capsize.
Sponsons are used on the fuselages of flying boats.

 Adjustable sponson system for watercraft - Patent 6032605
An adjustable sponson system for a watercraft includes a coupling mechanism that allows the position of the sponsons relative to the hull of the watercraft to be varied by the operator of the watercraft while seated on the watercraft.
Personal watercraft generally include a pair of sponsons which are positioned on opposite sides of the watercraft at the same position and in the same angular orientation relative to the outer chines of the watercraft hull.
The sponsons 12 are positioned approximate to the stem of the watercraft 10 and extend outwardly for increased buoyancy and stability.

Sponsons are preferably arranged on the underside of the flotation assembly.
The sponsons may be attached to the underside of the flotation device by enclosing them in a sponson chamber defined by a portion of the cover.
The exemplary sponsons 60 and 62 are symmetrically arranged on either side of the center line C such that the channel 66 is substantially parallel to the center line C. The sponsons 60 and 62 are mirror images of each other, and only one of these will be explained in detail herein.

 boats.com - Feature: Wing and a Prayer
Paddle or rudder type sponsons, which use a flat paddle-shaped rudder attached vertically to a block type sponson, do essentially the same thing, but the effect can be even more dramatic because the flat paddle or rudder portion of the sponson provides a sharper and more pronounced edge to catch the water.
The original equipment managers design their sponsons and position them on the hull with the average rider in mind, and generally lean toward the stable and forgiving side, so if you're looking for more aggressive handling, changing your the set-up of your sponsons is a good first step.
Because of their hull design, their sponsons need to be shorter because the flow of water off the hull is directed onto longer sponsons, which creates too much lift on the back end and counteracts any benefit the longer sponsons might have for handling.

Absent form this vehicle are the sponson machine guns although the aperture on the left hand sponson is clearly visible.
Apparently the sponson guns were probably more likely to hit their targets than the manually operated bow machine gun (so long as you wanted to shoot in the direction you were facing).
The right hand sponson aperture was similarly place to the outer edge this being necessary due to the way the ammunition fed into the guns.

 How to rebuild a sponson Radio Control Boat Modeler - Find Articles
Whenever it's possible, I use the WOF technique to rebuild a front sponson, primarily because foam is easy to shape, and when covered with 1/32- or 1/16-inch plywood and attached to the hull, such a repair is light and durable.
When you reconstruct a sponson, the most important part is the inside vertical section, which establishes the depth and length of the area being rebuilt.
To ensure the alignment of the sponson and the hull, you might have to enlarge the dowel holes slightly to provide them with "wiggle room." I also glue the dowel into the sponson first and let the glue cure to ensure the proper alignment of the parts.

The sponson cells currently contain self-sealing material on the lower one-third of the cell and full self-sealing on the inboard, forward and aft vertical walls.
Fire protection in the sponson dry bays is accomplished with the use of approximately 0.8 inches of rigid foam sandwiched between each fuel cell and the stiffeners of the forward and aft bulkhead.

That sponsons serve a useful purpose for those who are doing long crossings of open water in higher performance boats that have insufficient stability for easy re-entry or for proper rest at sea.

Sponsons are one method of solving certain problems but they aren't the only solution or maybe not even the best solution for some types of paddling or paddlers.

 Hawk Setup Tips
To set the rear sponsons, make sure the boat is on a flat table and that the turn fin and the rudder has been taken off.
To help in holding the sponson at the proper height while you are taping the sponson on, you might want to put a piece of 1/8" wood under the sponson to act like a shim.
The deeper left rear sponson transfers weight to the front right sponson to keep the turn fin in the water during high speed corners.

 Sponson Edges and Airfoils?? - Intlwaters Community Forum
I started adding front air dams(upright thin fins) to the front of the sponsons because the full size tunnel boats had them and I figured there must be a reason the "Big Boys" stick them on their big boats so J.D. started sticking them on his small boats.
This is important as when you start to turn the air at the front of the sponsons will spill over the sides and lose tunnel lift - eg the air needs to travel along not across the tunnel to get the job done.
Possibly combines the benefits of steeper sponson riding surfaces (grippier turns) with th increased speed of shallower angles on the sponsons.....could this be almost some kind of benefit for free???

 True Sponson Depth
The True Sponson Depth Should be 1 inch
The true sponson depth is the measurement from the bottom of the end of the sponsons (inside the tunnel) to the bottom of the boat.
Due to the break (where the bottom goes from flat to angled to meet the bow), sometimes a line needs to be extended on the inside of the tunnel to meet the trailing edge of the sponson.

When a watercraft goes into a hard turn the sponsons are put under extreme stress.
