Fun On the Water

Another long weekend is here….we hope it is all fun.   Please watch out for swimmers ….some are still venturing near the main channel and they are hard to see.  Hey ..watch out for the many duck families we have swimming around.  .  They seem to be in every sector of the lake.     Take care not to go too close to shore at speed..and try to avoid repetition circles when tubing.

Below is a note from the MLA and HERE is the full link.

How Boat Speed affects Wakes

You are responsible for the wake of your vessel whether the boat is in a “no wake” zone or not. If your wake damages property or injures people you have broken the law. Slowing down is the obvious solution, especially in narrow channels and near shore, but how you speed up and slow down is also important.

Below “hull speed” (about 8 mph for a 10 metre boat), a boat makes very little wake — the angled wave that is created by the bow and stern of the boat. As you increase speed beyond hull speed, the bow begins to rise and the wake from the bow begins to meet the wake from the stern, causing the combined wave to increase in height and volume. Both planing hulls (runabout) and displacement hulls (trawler) act in this way, but the planing hull can pass through “on step”, and plane at faster speed.

Just before the boat begins to lift onto plane and level out (this may require trim tabs), even a small boat can capsize nearby canoes or wash away shoreline. Between hull speed and planing speed, you also use much more fuel with very little increase in speed, and creating a large wake. For most planing hulls, the most economical speeds are hull speed and full, level plane. Have a look behind occasionally, when you pass moored boats, to see how your wake affects other boats and shoreline. Wake affects increase dramatically if the boat is operating in shallow water. Near vertical breakwaters, the wave will reflects back off the vertical surface, creating even larger waves.
