He said most of what he'd looked at topped out at around 230lbs. I'm sure there are models out there for the larger guy. any advice gratefully received.
Mick's suggestions with cockpit sizes are an excellent start, IMO. For a taller paddler, getting into the boat 'butt first' can be difficult, so a longer cockpit can be helpful. The deck height in front of the cockpit along with the beam will limit the foot/boot size that will fit, if that's an issue. BTW, there's a significant difference in clearance when wearing 'booties' vs neoprene boots with a sole (like Chotas) vs sneakers/wellies. If going to a boat tryout, I'd suggest taking paddling footwear.
As far as 'recommended load' for the boat, IMO having the boat a bit 'overloaded' is not a major problem. (Much worse, IMO is a too-light load, letting the boat 'sit on top' of the water and blow around.)
Looking at the specs for one of my favourite boats - Mariner Express (discontinued) - shows numbers for 150# and 250# loads, and for both conditions gives the
lbs per inch immersion which is the important number. If you're going to 'overload' a boat, look for a design that has a higher lb/in number. Unfortunately not all manufacturers provide full specs.
Is your friend looking for a boat for day-paddling or long trips? A boat loaded up with gear, food and water and a lighter paddler will be as heavy as your friend on a day paddle, I think. So I wouldn't worry overly about the recommended weight numbers, and just get a boat that 'fits' for now. Most paddlers don't stick with their first boat forever anyway.....
