Dasein tows a Quicksilver 230(?? I can't remember the model...) which we inherited from my in-laws when they upgraded. It has an inflatable floor and keel, and is rated 2 persons/610 lbs. Its extremely stable, but rows rather like a barge. It rows so badly that we bit the proverbial bullet and bought an outboard.

But it was free....

It's about 7 feet long.

Given the choice, I'd prefer a rigid tender... better rowing ability, if nothing else.
