I run the Big John Otter boats and love them! I use a mast about 6' long and the boards track well off to the side. I made some modifications, I hinged the keel so I can fold them for easy storage and I added a flag to each one for other boaters to see. They are great for lead core or braid with torpedo divers.
I've been on boats with BJ Otter Boats and they do work very well. My biggest objection for us guys with smaller size boats is their size. It's not like they will slide under a seat or into a compartment. The boogers are huge and the smaller the boat, the bigger they seem. I use the Offshore double ski models and they work just fine plus, they collapse and stow out of the way. It's not rocket science, I'm sure there are several brands that work equally well. Offshore does make a triple ski model as well. They work good but are a little overkill for me. I see walleye charters on Lake Erie using them with 6 or 8 lines per side.
They are big, that's why I modified the keel with a hinge. They fold up to the thickness of the main body. I'd post a picture but there on the boat in storage.
I made a set of double ski similar to the Offshore boards but did make options to fold them. They track as good as the Otter Boats but as BN says boat space is always needed. They're hanging in the garage un used!
