Vodkaman Posted May 13, 2009 Report Share Posted May 13, 2009 For those of you who build baits for use in seawater. Float testing in tap water is unrealistic, especially if you plan to design close to neutral buoyancy or a slow sinker. The solution is to make your own seawater equivalent. This is done by dissolving 35gm of table salt per litre of tap water. This will give a specific gravity (sg) of approximately 1.025, the accepted average sg for sea water. This could be fine tuned with the use of a cheap hydrometer. Dave Quote Link to comment Share on other sites More sharing options...
