Hey Michael,
You need to find a little used zodiac with a small portable outboard
Just something you could get out to the wind line and then anchor and rig off the back in Howe Sound. It would roll up and fit perfectly in your van.
15 years ago I had a Zodiac Cadet Fastroller 340 with the inflatable keel and a 25hp Merc 2-Stroke short shaft. No problems ripping over to Echo Island on Harrison Lake from Bear Creek in 3-4' swell..........with wetsuits on just in case.
Plenty stable for two guys and gear to rig on as well. It had an insane max weight rating and it didn't matter if it took some water over the bow. It rode very smooth and dry actually with the steep deadrise on the inflatable keel entry.
With 300' of 1/2" anchor rope and a 35 pound anchor you'd be set for Porteau Cove and a buddy. Worth mentioning with EOD setting in. Hope that El Niño pattern isn't taking hold after the stellar Fall snow and wind wise
Cheers,
Chris
