I decided to give Johnny a Milkor MGL 140 with a EoTech 552 holographic sight being in place place of the Armson OEG relfex sight. I'm also giving Katie a Beretta 3032 Tomcat which she keeps tucked between at the right side of her waistband (Greg firsts discovers the pistol seeing it tucked between the garter of her silk stockings while fooling around in bed).

isnt the namacurra kinda small? Im thinking a larger boat should be used seeing you have crew quarters, individual rooms. A 9m boat is more day boat than a seagoing one.

Any suggestions?

Can an EOTech 552 even function as an adequate sighting device for a grenade launcher?

EOTech does make a dedicated grenade sight which I imagine would work on an MGL, though.

do you mind if the boats not south african and is surplus from another country? I dont know boats well but I can make a search through google or something.

Good idea K9870. Let's make the ship a frigate.

Just gotta find a good model and research it a bit. Does the boat have any separate crew or just the main mercs, do the mercs have special jobs (like ship mechanic, navigation, pilot, damage control, etc?

Rocco serves as the mechanic while Johnny serves as pilot and navagation. The mercs are their own crew.

Might be way too hard to have just a few mercs....a bridge crew needs three (pilot, navigator, lookout.)
The same person can nav and steer in open ocean but going into a harbor is rediculous to try that. Also the line handling takes several people. maybe a small crew of locals that mans the ship and guards it while the mercs are on missions? Give you a few minor characters to develop and use in the story too.

Can you give me some names for the onboard crew? And what's line handling?
