Why so few hard tops on cuttys

I hear ya! I feel the same but on the other hand it would be very handy in some cases. I've now got two small boys and I want to take them fishing, they would need a place to get out of the sun. A hard top will do that plus give added structure to hold onto in rough seas. A bimini will not do that, and I HATE a bimini when it is not opened up.

Any suggestions?

I can see me now falling over a damn bimini and breaking my St Croix. By the way, I grew up with a Airslot 21. It was a great boat with a soft ride.
