I saw a rod online in a video that I really like the looks of, a lot! It is an inshore rod, Star Rods Sequence, 6’9” length, model SKT614S69. It is a light powered rod with a fast action. 
 

I read years ago that an inshore rod is about two powers heavier compared to the same rod rating in a bass rod. So I would assume that a light is closer to a medium (skipping medium light) in terms of bass rods. The line and lure ratings seem on par with a medium also, 6-14 pound line, 1/4-5/8oz lure rating. Would you agree? 
 

They also have a medium rod, rated at 8-17 pound line, and 1/4-3/4oz lure. This also seems on par with a medium, but if the two powers up theory holds true then this should feel like a heavy powered rod. Does anybody know?

For inshore, that typically means guys targeting redfish and trout with bass like lures.  Use the lure weight ratings.  I’d call the first a medium and the second a medium heavy in bass rod terms. 

It depends on the company and model of rod. I think Inshore rods just means the components are salt resistant. Some companies Inshore rods will have standard bass powers while some are a touch higher. For example: Tsunami carbon MH is rated up to 1 oz while a Penn Squadron M I have is rated up to 1 oz. 

Rod powers are totally subjective. Given that fact, it’s impossible to extrapolate what “2 powers “ even means. Saying that inshore rods typically are labeled with lighter descriptions than bass rods of similar weight range is about as far as I’d go. 

East coast rods and Japanese bay rods tend to be under-rated by about one power rating compared to bass rods. e.g, my Crowder ML - no, it's MM - 1/4-oz bottom-end.  

Gulf coast rods tend to be rated about the same power rating as bass rods, at least in part because we're fishing skinny water, and need our ML to fish 1/8 oz.  

Surf and offshore ML is another animal altogether, often with 2-oz top-end rating.

I have a Star inshore spinning. Seagis model.

7'6", 6-14 lb line, 1/4-5/8.

According to Calcutta (the maker) rod is a MH fast. It is very lightweight but has a very strong mid section. It is a great rod for speckled trout in the gulf casting hair jigs and small swimbaits.

Ratings on inshore rods can be tricky. I have a Crowder inshore MH spinning and that rating goes up to 2 oz.

It all depends on the company and Star is pretty consistent with a few other companies.  Its probably like a M with a good bit of tip.  

I agree with all the comments on the typical 7' inshore spinning rods. 

 

I would have agreed with the following comment for the past 30 or 40 years and then I bought a Penn surf rod earlier this year.

Penn Carnage III, 12-foot, 2-pc, ML, Mod Fast, 6-12# mono, 6-15# braid,  1/16 to 4-oz. lure.

I've had all sorts of rods over the past 60+ years, but that's a crazy lure rating. Works though.
