I am interested in a typhoon as a first "larger" boat. A reveiw I read suggested that the top speed is only about 5 knots. Is this true? If not, can you give me some examples of wind conditions and cruising speeds that you've seen. I'm not looking to buy a racer, but that sounds awfully slow.

Re: Typhoon Speed
Tom:
Here's the formula for theoretical maximum hull speed in knots of a displacement hull:
Square root of the LWL (length at the water line in feet) times 1.34.
Based on the Ty LWL of 13' 6" I get just about 5 knots. However, keep in mind that Carl Alberg designed most of his hulls so that at a few degrees of heel, the LWL actually increases, so you could expect a bit more than 5 knots.
As an example, the LWL on my CD27 is 20 feet which results in a theoretical max hull speed of 5.9 knots. In fact, while motoring I have never achieved a speed of 6 knots, always in the high fives. However, at a few degrees of heel in a fresh breeze I have regularly achieved a hull speed of 6.3 (with new sails). Working backwards, I calculate that while heeled I am getting an effective 2 extra feet of water line length, or about 10% more than flat.
Assuming the Ty design also gives you a similar 10% boost while heeled, you could expect to achieve about 5.5 knots. Now that's the theory. Having never sailed on a Typhoon, I would be interested in whether the theory is verified by the experiences of Typhoon sailors!!
Good luck in your decision process.

Re: Typhoon Speed
I am in my second season owning a typhoon. Compared to larger boats I guess it moves slowly and after a year I realized I would never reach the Gulf of Maine from my anchorage unless I went out overnight.
But a typhoon is not a sailboat for transportation from one point to another. The simplicity and beauty of sailing her make the speed irrevelant.

Re: Typhoon Speed
definitely, the trade-offs must be considered. you mention having had a larger boat. does it cost less to own and maintain the smaller typhoon? if yes, then harbor hop your way north and use some money to leave the boat at a marinain between . the typhoon is not great for overnighting compared to larger cruising yachts, ie no amenities, so stay at a classy marina. getting anywhere fast on any sailboat has never happened to me. i've sailed a bunch of different sizes. the whole point is to slow down and enjoy the journey. best wishes, PatB Friend Ship.

Re: Typhoon Speed
top speed is not the most important criteria for me. when cruising, i want safety, stability and a sea kindly motion. i've got that with the typhoon. this is the type of boat that will take care of you. Pat B 'Friend Ship'

Pat,
Thanks for the response. I bought that ty and have been enjoying it on Seneca Lake in NY for the last month.
