Product Description
How to order:
1. Float Size: Choose your size. We have two sizes available. A 20lb buoyancy float (spec sheet) and a 30lb buoyancy float (spec sheet). The 20lb version is suitable for the Core Sound 15 or 17. The 30lb float is suitable for the Core Sound 20.
2. Height: Choose your height. The standard height puts the float right at the top of the mast but If your boat has a mast head sheave above the top of the mast extrusion then the float needs to clear the sheave in order to rotate. In this case choose the EXTENDED mast option which will ship with 6" extra of PVC pipe and aluminum tubing so you can cut the floats "mast" exactly to suit your boat. See this diagram of how this works and feel free to send us a picture if you're not sure.
3. Attachment Bracket: Floats are installed using our "Side mount Brackets" (click here for pictures). Our Brackets are 3d printed from solid ASA plastic. The brackets are attached by drilling and tapping 10-32 stainless machine screws into the mast. Check out the size and option database. Check here if your boat is listed. You can also download a full size printout of available float brackets and choose the one that best fits. download the printout (be sure to choose "actual size" when printing).
