Re: AS 29
> I also have no feel for how many hp i need.This is a bit of a tricky area because some sailors are happy with enough hp to glide across a quiet anchorage and others want to do hull speed upwind into a gale. Different installations and propeller vary in efficiency. So, take what I'm about to say with grain of salt.
A rule of thumb is 4hp per ton. I found that a 5hp ob was fine for a sloop weighing about one long ton. My present boat is a bit less than 4 short tons, and is fine with a two cyl Yanmar that is about 16-18 hp. (There are different ratings for peak, long term, etc.) So my experience agrees. I know Hunter put the same Yanmar in a boat weighing over 5 tons, and I think it must be a bit underpowered.
So your 32hp ob should be fine. I can't advise on whether the installation needs reinforcement.

I hope to launch the first built AS 29 next weekend. The boat is in North Carolina and i am in Indiana. Hoping to make it to the OBX130. I do not remember seeing the boomkin for the mizzen on the boat and i do not have a set of plans. Does anyone know how it is rigged and how long it is?
