Re: [harryproa] Re: progress

25hp?  maybe you could go with an electric motor; one that is capable of 25 hp if enough current is applied.... maybe you don't have to actually apply that amount of current all of the time.

And what is meant by "fixed"?  Would a "fixed" prop that turned like a tank turret count as fixed?  The turret is fixed to the hull, right?

G'day,

The motor requirement us correct, and is a nuisance, not just because
of the weight, but the fixed prop in one hull is downright dangerous
and silly, both for cats and proas. They agreed that it is not ideal
and I suggested another option (minimum speed in flat water and/or a
bollard pull figure. They are considering this at their October
meeting, although I do not have very high hopes for an amendment.
The other requirements for Cat 1 are not too onerous, and weigh a
couple of hundred kgs. Most of them I agree with, but some do not
apply to harrys and I would seek an exemption.

Reality is, that an ultra light Solitarry may not be allowed to race
officially. However, if they were not prepared to modify the engine
rules, I think there is enough goodwill that it could be raced
unofficially (ie, no prizes), as long as it had enough engine capacity
to get in and out of the marinas. This is not such a big deal and
could be done without adding much weight, even if it had to be a fixed
prop.

From my point of view, just being allowed to start and sail with them
would be a huge step in the right direction.

regards,

Rob.
