When Zurk says open seas
I think you have to remember where he is!
Not saying it is right or wrong but he is in a capable little sib which will remain afloat bar the total air loss!
Where is your spirit of adventure you knockers?

I appreciate that you're probably joking, but I put a lot of thought to his question. He's having trouble with 4 foot waves and wants to go faster in them. I mess about quite a bit in a similar boat, going as far but closer to shore. Sea state is the big decider for me - a swell of 6' is no issue, but choppy waves are a nightmare - such a small boat with so much power is sooo easy to flip.

His issue isn't how far he's going, but what his plan is if he capsizes. A larger boat would solve a lot of his problems. A sense of adventure is fine, so long as you really understand the risks.

Wilks OK I agree if he wants to go out in these condition & go faster he needs a bigger boat!

All you can do to make the sib run in rough water is makes sure its inflated well, and engine and its mounts are perfect, AND GET TO THE GYMM TO MAN UP and open the throttle.......

If the total beeline distance from Vancouver to Nanaimo is 30 miles, the furthest off shore you could possibly be while along that path is 15 miles.

Aren't we back to the original problem of running a small craft in an area which may be subjected to large waves? It does not matter if you are one mile or 15 miles offshore, you are still facing the same problem.

Willk gives a thoughtful reply which pretty well covers the problem. Looking at the chart does indicate an out would be to take shelter on the far shore to wait out the worst of the sea conditions, but once you are navigating them, you must be certain you are self sufficient.

As far as an inflatable being sea worthy, they are used for life boats. As long as they do not capsize you are safe.

Running along the shore, you would not go out if the waves were 4 feet with a short fetch. If the sea state deteriorated while running though, you should have only a short run to calmer waters. That is completely different from making a long voyage and trying for speed with a small craft.

A spirit of adventure is one thing, but there are reasonable limits. You only have to over reach once to have a problem.

Remember that you need margins. I was out with the canoe club. Sea state nothing and a light breeze, but a slightly iffy forecast. A squall came through with the wind speed measured at 40kts. Within minutes we had sea state 3. None of this was an issue as we had an easy landing at any point, the wind was cross shore and the boats are good for sea state 4 at least, but it was a hell of an eye opener!

I know exactly where he is, my RIB is 15.5 ft long (33% bigger) and I don't go out in the Strait of Georgia with 4ft seas. Mostly because 4ft seas can turn into 8ft (or 12ft) seas, often with a 5 second period especially if the wind opposes the tide - they are punishing to the boat and me.

He may not be able to actually sink, but if the boat fully swamps (or flips) his gas will be water contaminated, his engine will stall and stop, and he'll be adrift in heavy seas with at best a handheld VHF to call someone to bail out his butt. And he'll be sitting in 50F water getting hypothermia.

Crappy seamanship all around.

know it too..

I've done that crossing a few years back from Eagle Harbour in a 28ft under sail. It's a great stretch, but wouldn't fancy it in a small SIB.
I am a cautious type though.. And in the world today fingers get pointed if you endanger others as a result of your actions.
