G'day all

a mate is looking to buy a boat in the 5.5-6.5m range 

several we have looked at don't have any form of top for sun and spray protection...has windscreen only 

just chasing an opinion on what it's gona cost roughly for either a set of rocket launchers and a hardtop or even just rocket launchers and a soft Bimini? I've had my clears in my boat replaced recently so I'm aware of the cost of that, more chasing the structural type cost.

will help with budgeting when looking at a few of them 

thanks for any advice
