Theory of waves

Waves can be measured in terms of height, wavelength and period. They all depend on wind speed, distance over open water which the wind blows and length of time the wind has been blowing over the area. So, as the wind begins to blow over the sea, waves start to form and the longer the wind blows the bigger the waves become. Waves max out at any given wind speed with enough duration. At that wind speed the sea can be said to be fully developed. They won't grow any further unless the wind increases in strength.

Stan and myself knew the forecast called for wind speeds of 40 kms/hr with gusts to 70 from the west. We thought that we'd take the ferry to Bell Island and paddle the west side of the island and be sheltered from the wind. When we got to Portugal Cove to catch the ferry it didn't look any better on the other side of the Tickle. We decided on St. Philips and were content to paddle squares, diagonals etc.

It didn't look too bad before we put in but after 2 hours the wind had whipped the sea up into some impressive waves. Paddling into the wind was at snail's pace, paddle so far, turn broadside to the waves, paddle some more and turn downwind. Communication in the wind was difficult but wasn't necessary. There were some excellent surf rides to be had down what felt like mountains of water.

I wouldn't do this without someone else along to help if needed. Stan made it possible today, thanks as usual Stan.

It was a great day of practice paddling in wind and waves. Why? So that we'll be able to handle it if the wind comes up on a day that starts out calm. Some people suggest that when the wind blows, it sucks. It only sucks if you're not prepared!
