Vertical windlass
The B361 is designed to have a vertical windlass installed - a Lewmar Concept model was used by the factory. It fits exactly right both below and above deck - there is little extra clearance in either spot, and the channel in the deck for the rode lines up as it should. In fact, there are small marks on the deck that help you line up the template used to drill the holes. There is also a wooden block below deck for mounting the dual-direction solenoid. I just installed a Lewmar V2 on my B361, which has nearly the same foot print and below deck motor, but is a newer design that's gotten nice reviews. It works great - best addition I've made yet. Keep in mind that the deck is over 3" thick where you'll be installing it, so don't even think about your battery drill. You'll also need to use 2awg cable from battery to the bow - I used 40' each way - a not inconsiderable expense. But the installation went well and there were few hitches, just stick with a Lewmar and it'll fit right.
