Looks like a good choice of extinguisher. Make sure you use a "marine" mounting bracket, not just the "hook on the wall" type. Trust me, you don't want one of these falling off the wall and accidentally discharging in your rig - not only is it a mess to clean up, but makes it hard to see if this happens anywhere near the cockpit. A Marine-type bracket has the extra strap that snaps around it to hold it in place. Called "Marine" since it is used on boats - same idea for our land yachts! ST
