Thought I might let you all know my own experience. I have spent many hours on my own 4.55m tinnie forward steer (post pics at later date). I have repainted, redone all electrics, new outboard, cut new floor, new carpet seats etc etc. This has taken some time and lots of love and care. I initially covered it with a cheap $40 cover that lasted about six months before falling apart. My next option was to go more expensive so for about $340 I purchased a great looking cover with plenty of straps. This has lasted about 12months but is starting to show signs of wear. It now has a small tear in it and I'll be buggered where it came from? The harsh sun of FNQ is taking its toll again so it seems. I am returning to Sydney soon and hoping to get a custom cover made although I admit I have no idea of cost. But to protect the "Little Prince" it would probably be worth it.
Cheers Flea
