Which sail to choose? Aerodynamics, Storage Space and Rigging Space.

How to get on the water in 20 minutes!

So which TIWAL Inflatable Sailing Dinghy Sail do you choose and is there really much difference?

Some questions to ask yourself:
How heavy am I or and how much sail area do I need?  What about family? 
Or
How experienced am I and how much sail do I need?  

If a TIWAL 2 is for taking on another bigger boat, what size boat do you have and will it be simpler and easier to use a sail without many battens?

Here are some answers which I hope will make your decision easier:

Will the buckles on the Reefable Sail affect airflow?
Sailing Dinghies sail close to the water and there is less wind down low due to a 'surface layer' of lighter wind.  So the bottom section of the sail isn't having a huge impact on your speed.   The top part of the sail is what matters. 
So will the boat still sail optimally?  The answer is yes.  The buckles will have a minimal effect on the speed of your boat. 

Will a battened sail 'hold its shape' for longer?
A full battened sail will 'hold its shape' longer than a sail without many battens.  

Will a sail made with monofilm (see-through material) last as long as a Daron sail?  
A sail with monofilm will last well, as long as the sail isn't folded along the monofilm. The TIWAL sails are designed to fold along the black Dacron. 

What is the benefit of the Furling Sail on the TIWAL 2?
A sail without many battens is easier to rig, handle, and stow on a smaller boat where having less room to move is an issue.   
The furling sail also wraps around the mast by removing the boom and undoing the vang and the traveller.  The sail wraps around the mast and is held in place using the velcro strip on the sail.   This is good for leaving the TIWAL 2 tied off the back of the boat when you are not using it.  

Do you want the option of having two sail sizes in one sail?
If you have multiple sailing abilities or sizes of people in your family then the Reefable sail is a good option for you! 

TIWAL 3: Do you have the room to keep two sails rigged to grab whichever one you need on the day for hassle free sailing?
If the answer if yes, purchase both the big and small sails and keep them rigged and ready to put straight on the mast and ready to go!
