Thunder | Peterson 34 | 34ft

Manitowoc, WI, US



Price Just Reduced in time for Spring Launch!

Very clean and well built boat. Professionally maintained and cared for by current owner, and stored indoors for the past 4 years. Excellent racing background, especially in single handed and shorthanded racing. Many upgrades and repairs have been made included but not limited to rudder bearings being replaced, new window ports, new tiller, non-skid repainted, new instruments, engine replaced, keel removed and re-bedded and templated, sails, and all standing and running rigging.

The Peterson 34 went into production at Texas-based Island Yachts/Composite Technologies, and 92 were built until production ceased in 1981. Composite Technologies, established by boat builder Andy Green in Corpus Christi, Texas, was acquired sometime around 1976 by boat builder and rigger Marion Hayes. Hayes renamed the company Island Yacht Corp. and relocated production to League City, Texas. 

It was during this era that Peterson’s designs dominated offshore racing, with winning IOR boats Gumboots, Eclipse, and Ragamuffin. He also designed several stock racers such as the Contessa 35 and the New York 40.

The majority of Peterson’s performance cruisers were considered rugged enough for ocean racing. Peterson once said the 34 “was built to deliver about eight people quickly and safely from point A to point B.”
