My opinion:
This is not competative.
I am a Noob with a crappy PC.
Forumwarriors tell us:
LRM are Noobweapon... so I go LRM and must disagree:
LRM is THE skillweapon - Lasers is just point and click and Ballistics are in between.
Hit and kill without Lock or high velocity is true mastery - Wannabepros like to call this luck.
With LRM you need to know the map... else you are going to waste ammo and get whacked by lights.
You need to know when to chainfire and when to blockfire, you don´t only need to know about Cooldown, Heat, Ghostheat and Velocity - there is also Spread to consider.
(k... with LRM you don´t need to know where the Hitboxes are - this might make up for Spread...^^ )
Use Boats with small launchers to get to know the maps. With LRM positioning is the key: Stick close to your team, spot, take fire (watch out for your XL though - if you are using one) and support everyone in need.
Your Range presents an opportunity to support elsewhere - don´t reduce yourself to a third line fighter.
The closer you are the more effective you become - with 220m your BAP can counter ECM - never get closer than 180m though and stay second line if you are using an XL.

Building Boats you NEED to know this.
Modules:
Advanced Target Decay... offensive, expensive, important, musthave.
Radar Depriviation: Counters enemies Target Decay... defensive, good for spotting and LRM-Dueling.
Advanced Sensors: Stackable with BAP this means you can spot as far as you can shoot.
Seismic Sensors: Some like them, I mention them. Less surprise Buttsex by Lights sneaking up on you.
Consumeables: UAV and a Strike... You are second line... if the enemy appears behind you, your team should know.
Weapon Modules: Get Cooldown first, Range second.
Clan LRM Boats:
Take 2-3 LRM15, BAP and a TAG - no Artemis.
Consider NARC depending on your playstyle.
For constant Rain you might consider 4-5x LRM5 instead of the LRM15. Again no Artemis.
LRM 10 are usefull in mixed builds - a waste otherwise.
I only experimented with SCR - there are others...
IS LRM Boats:
IS got heavier launchers and wider spread... thus I sometimes use Artemis.
LRM 5 (best ton usage), LRM 10 (compromise) and LRM15 (best overall) are general choices... LRM 20 are questionable right now: They waste a lot of ammo. Consider Quirks though... they change a lot.
4x LRM5 are needed for Rain with an insignificant pause; 5x LRM5 for true Rain (with modules).
BAP, TAG and NARC is the same as with Clans.
For Lights: I didn´t manage a good LRM Boat with these... though the Commando-3A has been fun.
For Mediums don´t forget to look at the Kintaros, Trebuchets and Hunchbacks. Due to their quirks those can dish out as heavier classes. Shadowhawk and Griffin are nice as well - I prefer them for SRMs though.
Hunchback:
http://mwo.smurfy-ne...07275426a89acf2
Consider to swap the SL for Artemis and/or ammo for AMS.
Trebuchet:
http://mwo.smurfy-ne...0f12b8ed9604777
Consider to swap armor and ammo for Artemis, JJ, AMS or SL
For Heavies: The Catapults are great LRM Boats.
Jaegermech-A, Orion-M and-VA are fun as well.
Catapult C1
http://mwo.smurfy-ne...f6629719035dc96
Consider to swap ammo for another Heatsink... or to swap ML for SL for another Heatsink and a full ton of AMS ammo.
Take 1-2 JJ instead of ammo.
Catapult A1
http://mwo.smurfy-ne...36fe9af61d46e4c
The classic - consider Artemis for 3 tons of ammo... I don´t think you need it though.
Jaegermech A
http://mwo.smurfy-ne...59ca70ee1ac890a
Consider to swap Tag, AMS and BAP for ammo... no secondary weaponsystem, you might want to swap ammo for an ML or SL in order to get assists if you scew up your positioning.
For Assaults: I love my Stalkers... Awesomes appear to be really good at it as well, as do the Battlemasters 1S.
Awesome 8R
http://mwo.smurfy-ne...b63bd2083155336
Consider to swap ammo and ML for AMS or more ammo.
Stalker 3H (heavy and slow LRM - LRM20 though...)
http://mwo.smurfy-ne...6be86a33a5bb591
250 STD
http://mwo.smurfy-ne...1a99ac2c4bed96a
255 XL - more ammo, less tanking.
Stalker 3F
http://mwo.smurfy-ne...cbcec742102dd4b
This is not a Boat... but a nice alrounder even for CW.
300 STD - Consider smaller engine and Artemis.
Stalker 5M
http://mwo.smurfy-ne...8527bd044664e0d
300 STD - This is nice Rain and good in order to get to know the maps... I suggest to use a SRM6 version, though this thing is fun...
Battlemaster 1S
http://mwo.smurfy-ne...b638948a63ffa8d
275 STD - Heavy 4xLRM10
Game Modes:
LRM Boats reap great rewards if the enemy is unorganized - solo PUG is easy once you know the maps and how to position.
Against organized groups you are going to have a harder time. LRMs are easy to counter and avoid - often you have to wait for the enemy to make mistakes. If the enemy is communicating all you can do is suppress and hope for them to play into your hands.
In CW as IS LRMs are highly situational and really hard to play.
I suggest not to bring LRM Boats if you aren´t in a premade who roll with it... LRM as a secondary weapon is another thing all together (thus Clans with their light launchers can do this easily).
Your team needs the right composition for Boats in order to be able to tank enough... even then it´s hard to spend all ammo before your Wave is spend (there is a lot of ECM in CW). To my experience LRM are secondary weapons for Heavies and Assaults and a Medium boating LRM is viable - this takes practice in order to become efficient.
Right now for CW I am not fielding any LRM-Boats anymore, even though I consider myself a Lurmer.
