Hi,
I recently rigged a 2022 NP Combat 4.5 on a TPX100 370 RDM Mast from 2022 and it had a beautiful profile for a small sail (and sailed really well too, lot's of grunt but will depowered when it needs to be). This new Combat has a 'relatively' deep tummy compared to my older 2017 Combat 4.0 which I rigged on an older (2014) X65 340 RDM Mast and which always rigs quite 'flat'.
So I was perusing the Unifiber page and the Neil Pryde Web Pages for Mast information and (see pics below). It seems that (using Unifiber data only) NP was "Flex Top" (FT) for both RDM and SDM from 2011 through 2014 Charts (2011/2012/2013/2014), after which in 2017 there was a minor shift towards Constant Curve (CC), but still denoted FT, for RDM only. This continued for the 2019 Chart.
Unifiber changed their chart in 2023 to a different system, but it shows that at the 2015/2016 boundary it moved to CC (which frustratingly isn't actually consistent with Unifiber's own 2017 and 2019 Charts).
The 2017 Combat 4.0 which rigs on a 340 or 370 mast (so yeah I could try on the new mast) but as I also have a newer Combat 4.0, which ONLY rigs on a 340, I was wondering if anyone had any experience with rigging a post 2016 or 2017 Combat on an older X65 Mast vs a newer TPX90 or TPX100 340 RDM mast and if there was any appreciable difference?
I appreciate this might simply be down to cut of the sail, but if anyone who knows / has had / rigs these sails regularly and has a good eye for them could put their 2cents in, that'd be great and much appreciated.
Cheers
k.
