Mike,
The Orkney, Raider and Warrior are all in the same size class but IMO cant be compared with each other, they all have good and bad points, all are class leading depending on what you need / want from a boat.
You really need to get out on each of them to see what I mean.
The bad points in each Ive noticed:
Orkney - Low freeboard, rolls and leans when moving around them
Warrior - Ride is hard and slow when not on plane
Raider - Slap, slap, slap when at anchor, ride not as smooth as a V hull
The Orkney is a cracking boat of you are looking for good fuel economy - I dont know of another 16' boat that will get anywhere near it. It also rides well.
I'd say that if you fish up to 5/6 miles from nearest point of land then they are a great boat. I'd feel concerned any further offshore that that.
But as I said - get out it them - a sea trial is worth 100 forum posts and advice.
Hope this helps.
