The distance to the horizon for any height of eye (HE) is 8/7 * sqrt (HE). So to avoid having to do a dip-short, you'd need a distance of at least 3.7 miles clear view of the water from your location. BTW, the official constant for distance to horizon is 1.17 rather than 8/7 (1.14) but it's a lot easier to calculate using 8/7 (especially in one's head).
