A Few FAQs...

Based on the published Design Ratios for the Island Packet 350, how would you expect the boat to perform under sail?

The Design Ratios indicate that the Island Packet 350 is a moderate to heavy displacement boat with a good balance of sail area and ballast. It is not designed to be a fast or agile boat, but rather a stable and comfortable one. It can handle a wide range of wind and sea conditions, but may not point as high or accelerate as quickly as lighter or more performance-oriented boats. It is best suited for cruising rather than racing.

Is the Island Packet 350 still in production and, if not, when did production end and how many of these sailboats were built?

The Island Packet 350 is no longer in production. Production ended in 2004, after eight years of manufacturing. According to the Island Packet Yacht Owners Association, a total of 178 boats were built.

Is the mast on the Island Packet 350 deck stepped or keel stepped?

The mast on the Island Packet 350 is keel stepped. This means that the mast stands on the keel at the bottom of the hull, and passes through a hole in the deck and the cabin. This is different from a deck stepped mast, which stands on the top of the deck and does not enter the cabin, although a compression post transfers the load from the deck to the keel.

Some of the advantages of a keel stepped mast are that it is stiffer, stronger, and more stable than a deck stepped mast, as it has one more point of contact with the boat structure. Some of the disadvantages are that it takes up space in the cabin, and it can allow water to leak into the bilge.

How many people can sleep on board an Island Packet 350?

The Island Packet 350 can sleep up to six people on board. There are two double cabins: one forward with a V-berth and one aft with an athwartships berth. There is also a U-shaped dinette in the saloon that can convert into a double berth.

How did the sailing press review the Island Packet 350?
