Tartan 4100: Bob Perry Design Review

The Tartan 4100 has a beautiful hull shape. The entry is gently V-ed. As you proceed aft the bilge gets a moderate turn that hardens slightly toward the stern. The deadrise angle is almost a constant 10.5 degrees from station 2 to amidships. This angle flattens out to 3 degrees at station 10.

The Tartan 4100 under sail.

The boat has a gentle hull form that should avoid pounding when motoring into a chop. It should also have good light-air potential and the ability to get up and scoot when the breeze is at your back. The stern is broad at deck level and overall beam at the waterline is moderate. The D/L ratio is 185.6. A centerboard model is also available with additional displacement and a beavertail-type bulb keel to help enhance stability. Standard draft is 7 feet.

The sailplan shows a flattish but attractive sheerline. The rig is a sloop with swept double spreaders and mid-boom sheeting. The SA/D ratio is 18.22.

Tartan is offering three interior options with this 41-footer. The standard layout features two double-berth staterooms and the head, with a walk-through shower stall located aft. Note the angled berth aft. You can also choose a tri-cabin layout, with two double-berth staterooms aft and the head moved to amidships. If you have to have two heads, you can modify this layout by adding another head to starboard just forward of the settee. I like the way the angled bulkheads work in this design to open up the settee area and create an inviting space.

A design for sailors who want the best of comfort and speed.
