#28 HMNZS Monowai - Done

Let's look at the only 2 other ships with Repair:

Nordmark 5pts
Speed 2
MG: 5/5/4/3 
AA: 5
A/V/H: 1/7/4
Slow 2, Repair

Vestral 4pts
Speed 1
MG: 3/3/2
AA: 5
A/V/H: 1/6/3
Repair, Hidden Operations

Comparing Repair vs. Reinforce Installation vs, Supply Run:

Repair: Once per game prior to movement, you can attempt to repair a local friendly ship. If so, neither unit can move or use gun attacks that turn. At turn end, on a die roll of 2 or more, remove 1 pt of hull damage

Reinforce Installation - Instead of attacking during your Surface Attack step, this unit can Reinforce Installation on a damaged Installation in an adjacent sector. If it does, roll a die. On a 4 or higher, remove 1 point of hull damage from the Installation at the end of the turn. An Installation may not remove more than 1 point of hull damage per turn. You may remove only 1 point of hull damage per game with this ability.

Supply Run: Instead of attacking during your Air Attack step, this unit can make a Supply Run in its sector. If it does, roll a die. On a 4 or higher, remove 1 hull point of damage from an Installation in this sector at the end of the turn.

Notes:
- None of the repair abilities allow you to attacking (though it could be argued that you can use Smoke/Torps with Repair, but it repairs a ship on 2+).
- Reinforce Installation allows the Installation to fire, but succeeds half the time... just like supply run.
- Supply Run has no limit to the number of times it can be used in a game or turn.  (Yes, I've used 3 of them in conjunction with a HSB... most I've healed in a turn was 2)

I could see an argument that the Monawi should be 4/5 points, so I think 5 points is the right call, especially with how Reinforce Installation is currently worded. 

Nordmark was the problem I had. It was an under costed unit from set 1

A cheap hull 4 can be really dangerous in small point battles.

“You can use this ability” is always redundant.

Reinforce Installation - Instead of attacking during your Surface Attack step, this unit can use Reinforce Installation on a friendly Installation in an adjacent sector. If it does, roll a die. On a 4 or higher, immediately remove 1 point of hull damage from the Installation. You can only use Reinforce Installation once per game.

Reinforce Installation - Once per game, instead of attacking during your Surface Attack step roll a die. On a 4 or higher, immediately remove 1 point of hull damage from a friendly Installation in an adjacent sector.

Good point. I would say yes.
