My Predictions:
1st VIII
I don't think that shore will win the 1st VIII division. They are no where near in the clear yet. only showing up to 2 races (winning both) and as the Newington 2nd VIII has shown shore eights ARE beatable. I predict the top 4 to be shore, Scots, new and Joey's (in no order). Given the amount of depth shown in the Newington shed I see them as big contenders for the Major Rennie, and Joeys and Scots have shown improvements with big promise for quick times in march. Shore has proven that they can move a boat fast, but only time will tell if they can continue to improve. Grammar and High haven't shown anything promising yet, but anything can happen. N.B Rumor has it that with both shore and joey's bow-rigging their eights, Kings, grammar and scots have all decided to do the same so 5/8 1st VIII's will be bow rigged, with possibly more by march.
I'm sorry, but there's a lot of things you have said here that are completely wrong.
Shore are so far looking almost unbeatable. You said it yourself, they are unbeaten. Their 6:02 at SIRC is admirable and with 4 more months of training I would expect that to be around 5:55 or lower by HOTR.
Newington are nothing special. They have yet to show a performance worthy of your claim.
Scots have shown themselves to be very inconsistent, with a second at Iron Cove and a 5th at SIRC, whether they can perform on the 9th of March remains to be seen.
Riverview are proving to be quite a force to be reckoned with this year, significantly better than previous years. This may be as a result of the appointment of dual olympian and world record holder Daniel Noonan as the head coach. Also, they were spotted training in crews during the off season, an act that is in direct contravention of the GPS code of conduct.
Joeys are rowing well this year as well, but are nothing special. They came second at SIRC with a very strong time of 6:05 but were beaten at Gold Cup by Grammar and Riverview in the Semi-Final and Scots in the Heat.
Grammar won the Head of the Parramatta by a strong margin, beating Newington by 14 seconds and Kings by 28. Despite these two and High being the only competitors it was a very strong result. They haven't performed in the other races thus far, but their performance at Gold Cup showed that they have the ability to beat some of the better crews in the GPS (they beat Joeys in the heat). The Grammar shed has a clear lack of depth, which the extremely poor 2nd VIII shows.
Kings have been poor up until the Gold Cup at which they performed admirably, beating Scots and Newington convincingly in the Semi, and racing competitively in the final.
High is still battling at the rear of the field. They are really the only ones completely out of contention for a podium finish at HOTR. I do admire them however, for continually showing up to compete.
Now, onto your claim about the some eights being bow rigged. Not only does it have almost no bearing on anything, but the Grammar eight is not bow rigged, neither is Kings's eight. I can't comment on Scots.
Good to see some TAS crews out at the Reindeer Regatta. Granted, both slow times and poor placings but it is good to see a resurgence of their rowing program.
Also, I believe the coxswain of the GPS VIII is the cox of the winning crew at Head of the River.
