17' Arima Sea Ranger. 75hp main, 9.9 kicker. Pretty stable trolling platform, not particularly fast from a to b. The general idea was going to be to pick a likely window of opportunity and do 5 days or so out of WH itself, bookended with a week on the east side out of McNeill. Flexible now as to what timing most likely to be ideal, but would have to book in advance both for vacation time from work and accommodation in WH.
Whether it was wise or not, the last 7 years I've taken my 17ft aluminum bow rider to Quatsino Sound in July (dark blue with a pink stripe - probably a few here might recall my wee boat out there). Never had a day where I couldn't fish cliffe or kains for at least the morning. I even made it to Grant Bay once a couple years ago, but only once and never again... way to f-ing risky for an open boat between the wind and the fog or both...
With the small boat fishing, we always came home with fish, but fishing the inside waters is no where as good as the outside. But if you're ok with the inside, your Arima will be just fine. I'm always with a group of 3 boats. Buddy with a 24ft Hewes, and my father-in-law makes do with his 16.5ft lund, though he wisely focusses on the inside waters and I usually keep him company when I had my 17footer.
But now I have an 18 1/2ft glass boat with a cuddy/closed bow and was outside every day on our last trip at the end of July this year. Felt very comfortable in the afternoon wind running home from Lawn Point or from 3-4 miles off Grant Bay. But I always check 3 wind models and keep my eyes and ears open for changing conditions and have yet to get caught out too late.
That being said, I know there are days when it's not suitable for that small of a boat, but on those days, it would still be very lumpy running in a 24 or even a 30ft offshore boat and I probably wouldnt go into a 15-20 knot wind with 3-4ft chop on top of the swell, but that's just me.
I've seen plenty of 14ft skiffs at Kains and Cliffe, so I guess a lot depends on your comfort level and whether you have a buddy along in a second boat.
Trouble with planning back up fishing out of McNeill/Hardy is that area 12 is the regs are so constrained for openings in July and early August. I don't even bother fishing in my back yard unless I'm out with the family for whales. And running from Hardy to Sutil has about the same overall exposure and risks as fishing Quatsino Sound and outside waters. I'd feel safer in either your or my boat off Kains or Cliffe rather than Sutil...
