Here's a cross section of what I ended up with. As i said next time I would not use bubble wrap - possibly just a layer of builder's film instead to tape the card to. I would use extra card instead.
This ultimately only just squeezed into a high quality board bag. Seeing as you do not have a bag then the pool noodle or extra packaging would be advisable on the rails. Perhaps multiple layers of card and duct tape (half a dozen) will do just as well and you could wrap that around more of the rail as I think pool noodle has a fairly small diameter and may not reach around far enough. Try storage or removals suppliers for the card. Laminating over the card with duct tape really toughens it up too, adding impact resistance. It's got to be good quality stuff though. I found Bear brand at Bunnings for 5 dollars per roll which I though was good. The cheap stuff just doesn't stick.
I think I eventually ended up four or five layers thick on the nose and tail, laminated card and duct tape - felt like a boxing glove on each end.
Also, if you can find some tough cardboard boxes cut them up into broad sheets to go on the bottom and deck of the board as extra armour plating for those areas. You're only doing this once so there's no need to skimp on the thickness of your packaging.
Both my booms had passed their use-by dates so I left them behind and bought new in NZ. One of these was couriered from Dunedin and had been heavily packed with bubble wrap around the arms and card around the head. Pretty hard to break a boom though.
Here is how I packed the masts and sails:
