5ppl on a kayak. Must have been a Hobie Tandem Island (trimaran). I have one. If he flipped it. It would be really hard to right it.
I’m not too sure I’d have ever left the boat -really hard to sink....
My first "big boat" experience was up there in an old Morgan 38. The water temperature is in the upper 40's to upper 50 something, I'd guess. It was "take your breath away" cold. If the water is stirred-up by waves, it gets a lot colder.
Horrible and heart breaking.
I can't imagine taking kids out on a canoe or row boat in Lake Superior like that. It's just too unforgiving.

Below is a graph of Historical Sea Surface Temperature for Apostle Islands. This has been derived from analysis of two decades of oceanographic satellite measurements of nearby open water. We have calculated the average water temperature variation around the year as well as the extremes that have been observed on each date.
All of the graphs for the surf breaks presented on Surf-Forecast.com are on the same scale to enable comparison between locations around the world.
Apostle Islands sea temperatures peak in the range 12 to 19°C (54 to 66°F) on around the 14th of August and are at their minimum on about the 15th of March, in the range 1 to 2°C (34 to 36°F). The maximum seasonal sea temperatures at Apostle Islands in mid August lend themselves to a 4/3mm wetsuit or a 3/2mm suit and 3mm neoprene boots. The minimum sea temperatures at Apostle Islands mean that you will need a flexible 6/5/4mm wetsuit or a well fitting 5/4mm wetsuit with gloves and 5mm neoprene booties and a hood to surf here in mid March.
Actual sea surface water temperatures close to shore at Apostle Islands can vary by several degrees compared with these open water averages. This is especially true after heavy rain, close to river mouths or after long periods of strong offshore winds. Offshore winds cause colder deep water to replace surface water that has been warmed by the sun. Air temperature, wind-chill and sunshine should also be considered before deciding on the kind of wetsuit needed to stay warm when surfing at Apostle Islands.
