Hi all,

how much would be single or double board bag new? I'm going to mauritius in july and i'll have to buy some bags to carry a waveboard, 2masts, 1 boom, 2 sails (i might just bring 1 mast and 1 sail but dunno yet)+ a surf board. If anyone has like a quiver bag 4 sale i'd be interested.
Cheers

My mate has quiver bag for sale. It's at 2nd wind (in Perth) on consignment if you want to have a look.

Cheers

Hi X Man, tell me about Mauritius as a sailing destination. Conditions, gear availability, weather, cost etc. I'm looking at this as an alternative to Maui perhaps.

Hi X-man,

I would recommend you get a separate board bag and sail bag. I used to pack everything into one bag but given that airlines now don't take bags over 32 kgs it's easier to split gear.

Neil Pryde makes some great quiverbags. They are about $280 and fit 3 masts plus 5 to 6 sails, wetsuit, harness, extensions etc.. All that will probably be about 20 to 30 kgs.

As for board bags, again Pryde has some decent bags with enough padding for flying. They come in single and double size. Double usually fits 2 boards + a boom. Or get a single bag for a board plus boom. I usually pack everything with some buggle wrap and a few towels for extra padding.

I am sure other companies make great bags too... make sure though look for quality zippers (YKK is a good brand) with "big teeth". Also make sure there is enough padding on the tip and rails.

Definitely take all your gear to the shop and try it out first. Never force any zippers and absolutley make sure you take out that valve screw out of your board.

Also, never overpack a bag... the friendly guys and gals at the airport will definelty make you re-pack if they don't like the total weight... as I said usually bags are not allowed to be over 32kgs due to OHS regulations. make sure you check specifics with the airline.

hope this helps...

X-man, if you only have 2 sails, just roll them up together and stuff them in the one sail bag (the bigger of the two obviously).
They now will only take up the same room as 1 sail. Take the other sail bag with you and seperate them when you get there.

And don't take a separate bag for clothes. It's a waste of space. Just stuff all your clothes in your board bag. It doubles as padding as well.

Cheers for the replys guys great tips indeed, but why is it important to take out the valve screw? I guess it's because of the temperature changes but what happens to boards that don't have any?

Waiting4wind, mauritius is my home country so I can tell you we get pretty good conditions at this time of the year, with usually consistant winds. I was always on 5m or 4.5m sails. August/september are the best months but i'm going in july coz its my uni holidays.

If you're going 4 solid wave riding there's 1 place to go its Le Morne. The reef configuration offers a great variety of waves, and you can sail from 1 spot to the other in no time, the ultimate being Oneye fast and powerfull(Ricky Van der toorn snaped his tibia landing an aerial on it in 1998). If you go there ask about the currents as they are very strong near Oneye. I plan to camp at least a full week there.

Otherwise the whole east and north coast is great for freeriding with some other wave spots. For accomodation you have the hotels at Le Morne with club mistral and all but they're expensive. See if you can rent a little bungalow somewhere.

Best winds.

I was told that you shouldn't take the valve out completely, but definately loosen it so that it is no longer sealed.
The reason for not leaving it sealed is not necessarily because of temperature, but because of pressure changes. Even though the cargo hold of most commercial planes is pressurized along with the cabin, they're not pressurized at sea level (or airport level), but at a few thousand feet. Because (pressure1 x volume1)/temperature1=(pressure2 x volume2)/temperature2, as the aircraft climbs and the air pressure in the hold decreases to a cruising pressure, if your board was sealed, ie. v1 = v2 and the reduction in temperature (in degrees Kelvin) isn't that great, basically the pressure inside the board increases. The epoxy skin is likely to separate from the core. If, as a serious student of science, you want to investigate this, take a packet of chips into the plane, noting how "inflated" it seems at the airport, the watch how the bag expands as the aircraft climbs. If your rigid board, which contains heaps of gas, wasn't allowed to vent that gas to realease pressure in the board, you are likely to have it either want to blow up like a balloon, or break the eggshell of epoxy. Isn't science fun??

Maybe this could be a good way for Harrow to get the water out of his board- by atmosheric pressure reduction therapy. Only costs a few plane fares.

Chit, I amaze myself sometimes. Seems like I can still remember high school physics. Found out that planes pressurize at about 6000ft, or roughly 2000m. The atmospheric pressure at 2000m is about 80% of that at around sea level. Assuming the temperature of your board changes from 20C to freezing, ie 293K to 273K, if you had a 100 litre board, using the gas formula, your board actually wanto to change into about a 116 litre board if it were to keep its internal pressure the same at the surrounding pressure. Not really sure what internal pressures a board can stand, but that's why they give you a vent screw.

As MikeyS says, it's pressure that's the problem!!!
The weak point is the tensile strength of the inner core, this very poor.
And with open cell foam, the pressure in the whole volume can travel to the weakest spot, only needs one of those little beads to come loose and delam starts.
Hopefully boards without vents are made from closed cell foam. Not only do they have the advantage of not sucking water, the increased pressure only happens on a cell by cell basis, so even if there is a weak spot it doesn't spread.

soooo...... if a man was in the unpressurised cargo hold for the trip would he explode from say 90 litres of volume to a lot more or would he just die of lack of oxygen. i've heard some people have survived!
and none of my vacuum bagged, coremat, divinycell, styro boards ever exploded in an aircraft.
science is cool in theory.

task 1. try to wreck a board by driving over it repeatedly with your car. it's a hard, hard ask. sh1t they're tough!!!!
altitude? i don't think so.
....but prove me wrong.

Yeah when I was talking about temperature I was indeed thinking about pressure. The thing is that the cabins are pressurised but where they put the luggage it's usually very cold (not too sure if this applies to recent airliners), so I don't think the gas inside the board will expand but actually retract. Thanks for the advice I'll unscrew it anyway!

Greenleader, remember its only the gases in your 90 litre man that would expand. Most of him is made up of water and solids. So if he held his breath and clenched his butt ring to keep all the fart gas in, that part of him would expand.
People die at high altitude because the pressure of oxygen (partial pressure) is too low for there to be adequate bonding of oxygen to the haemoglobin in their blood (to simplify it a bit). And I'm not denying that boards may be strong enough to survive pretty rough compression from the outside, ie driving over it. The core would support the deck to resist that kind of force. But that's different to increased pressure on the inside of the board, like the reverse of vacuum bagging. I guess different materials and constructions have different bonding strengths to resist delaminating. I'm not questioning that your boards have survived, Greenleader, but if the manufacturers of other boards think there's a risk of delaminating so they put a valve in, my guess is that they aren't doing it just for fun.
And X-man, I had already allowed for the drop in temperature, assuming that the board is loaded into the plane at about 20 C and that it cools to 0 C. The hold probably doesn't get to freezing, but I have been generous. The dogs and cats in the hold tend not to freeze. The temperature change only reduced the board volume by 7%, but the atmospheric pressure change increases the volume by 20%.
So, how much were those board bags again?

I read somewhere once that years ago a old Division II board on a BA flight exploded in the hold. Lots of very scared and unhappy passengers. It trashed a lot of luggage too!!
Hence to say, no more hollow un-vented boards on airlines.

If it doesn't have a vent screw drill a small hole in it and just araldite it up afterwards.
