I am trying to build a gunslinger character for a naval warfare Pathfinder campaign. In a nutshell, this character would mostly stay on a boat and fire siege engines at enemy ships. I intend to take the [siege gunner](http://www.d20pfsrd.com/classes/base-classes/gunslinger/archetypes/paizo---gunslinger-archetypes/siege-gunner-gunslinger-archetype) gunslinger archetype. The next step is to select feats, but I'm not entirely sure which combat feats are applicable to naval siege engines.

For starters, the [rules of using naval siege engines](http://www.d20pfsrd.com/gamemastering/other-rules/ship-combat/naval-siege-engines) lists 4 specific feats: [Siege Gunner](http://www.d20pfsrd.com/feats/combat-feats/siege-gunner-combat), [Siege Engineer](http://www.d20pfsrd.com/feats/combat-feats/siege-engineer-combat), [Master Siege Engineer](http://www.d20pfsrd.com/feats/combat-feats/master-siege-engineer-combat), and [Siege Commander](http://www.d20pfsrd.com/feats/combat-feats/siege-commander-combat). These rules also mention that critical feats of the siege engine operators *cannot* be applied.

But what about other combat feats, specifically those that branch from the [Point-Blank Shot](https://sites.google.com/site/pathfinderogc/feats/combat-feats/point-blank-shot-combat---final) feat? For example, the [Far Shot](http://www.d20pfsrd.com/feats/combat-feats/far-shot-combat---final) feat would be helpful for targeting faraway boats, while [Deadly Aim](http://www.d20pfsrd.com/feats/combat-feats/deadly-aim-combat) could be useful for dealing with boats that get too close. 

I think that the feats that mention one type of weapon (bow, crossbow, etc.) would not apply. I don't know of any siege weapons can be fired multiple times per turn, therefore any feats involving multiple attacks would also not apply.

**Among the ranged combat feats that branch from Point-Blank Shot, which ones are usable with ranged siege engines?**
