Why don't you try a trial cruise
Island; this cruise will get you out into the "big" stuff and you will be more able to develop an informed opinion on how well your boat will do. There is a new book out that does a good job of describing good cruising areas; and, how to cruise the west side of the Island; unfortunately I don't remember the name of it, but it is something like "Westward Bound".
Don't be put off by the "Island" label of this cruise; Vancouver
Island is larger than Japan
and one third the size of Britain, so you'll have an adventure I promise.
You need to know what you are doing on this cruise (remember coastal cruising is often much more challenging than out on there on the deep blue sea); currents can be profound at Easterly Northern end of the islands. The number of ship wrecks off of the west coast
of the Island is high. The reason the famous West Coast
Trail on the Island was developed was to offer ship wrecked victims and area to walk once they came ashore. If you cruise in the summer, you'll be okay. The latest I would go is with a cruise that ends at the end of September and doesn't start until May. Realize your weather
is very much like our weather
, June can be a crap shoot as to the quality of the weather. The very best time to cruise would be from 15 July to 15 August.
For this cruise, if you don't have one, I'd recommend you install a chart plotter before you go.
