That assumes your CG is directly over the gunwale when perching and 50cm from it when hiking hard. A Laser is 145cm wide so, in round figures the perching leverage is half that or 73cm and the hiking leverage is 123cm, going from hiking to perching reduces the leverage by 41%. In the Blaze those figures are 125cm and 175cm, a difference of 29%.
The wide boat delivers more power for the guy wanting to perch too, 71% more in a Blaze compared to a Laser. and a perching sailor in a Blaze still has more leverage than a hard hiking Laseratti. In both cases the loss of power is significant though and ain't gonna win you races  Cry



Yes, well, if we're going for a numerical approach then let me proffer this bad boy:
Perching (P) versus Hinking (H) where overall energy output (OO) = the amount of arse projected beyond one's dinghies' centreline.
Therefore, maximizing your dangling provides the maximum amount of POOH.
Whereas balancing ones nether regions on the edge of a rack, gunwhale or sliding seat can also provides leverage, but in some or most cases, for a lot less POOH.
Or it could just be BS depending on the amount of leg pulling you are willing to do (quite literally) of a Friday lunchtime.

Blaze still looks like a great option for open water and sea sailing... I guess now the Halo sail rigs on the same hardware it makes more viable for an evening summer boat too... especially the 20 year old ones for 1500 quid

How true, I wonder if that's why we're always smiling while the Laseratti are all gurning?  Big smile Or could it be the Blaze is just a hoot to sail.......

Plus you don’t want to look like you’re taking it too seriously in a Blaze....  it doesn’t go with the naked dancing, all male, getting utterly wasted vibe of the class.

But if you're dangling your ar5e over the edge i'n't that called hiking?  Confused

Plus in a Laser if you perch your arse is going to drag whereas in a Blaze (or H2) you can dangle your arse over the edge and be a long way off the water!

Extreme width does mean that extreme hiking doesn't reward the energetic quite as much as in a narrower boat so taking a breather upwind when it's blowing doesn't carry the same penalty but hiking hard for as long as you can still pays off.


You can take a breather in terms of getting the boat round the course but not in relative performance terms. A wide boat delivers more performance for the sailor prepared to hike harder. If you want to perch go narrow!

You can (could) pick up Zeroes very cheap second hand. I think they have gone up again as the dealer is being more proactive in determining prices, but doubtless there are still deals to be done.
