Prop and Shaft Check
A vessels drive train is typically defined as the components between the engine transmission coupling and the bitter end of the propeller shaft. For traditional drive trains, this includes the propeller, shaft, cutless bearing and packing gland, although the list could also be expanded to encompass ancillary items such as the rudder, engine mounts, and engine bedworks. Heres a look at two major drive train components you should know and what to look for when inspecting each. Next month well look at the components inside the boat-stuffing box, shaft, and coupler.
Determining a Fuel-efficient Engine RPM
My boat is a Hans Christian 41T, with a waterline length of 36 feet and a displacement of 38,000 pounds. The engine is a Volvo Penta TMD-30A rated at 90 horsepower. The prop is a Maxprop, three-blade, 20-inch prop with 12-inch pitch. A table illustrating speed at various RPMs shows that there is a linear increase of speed with RPM up to about 6 knots (2,600 RPM), but then the speed tapers off with increased RPM. Based on this, I presume that motoring at about 2,600 RPM is optimal fuel burn and speed. Is this correct?

Fair Through Hull Fittings: Essential to a Smooth Bottom
In light air, a major portion of the total resistance of a sailboat derives from skin friction. To oversimplify, the smoother the boat's "skin" — the submerged part of the vessel — the less power is required to drive it to a given speed. Put another way, given two boats identical in every way, including sail area, the boat with the smoother bottom will be slightly faster than a boat with a rough bottom in light air. Most racing sailors have learned the value of a smooth bottom. Ironically, cruising sailors can benefit at least as much from the creation of a low-resistance bottom as racing sailors, although you rarely see a cruising or daysailing boat with a bottom to match that of a good racing boat.

Some Propane Dos and Don’ts
Theres nothing more satisfying than capping a pleasant day on the water with a good meal, be it burgers and dogs on the grill or some fancy, culinary extravaganza whipped up by the galley wizard. Most marine stoves and grills use liquefied petroleum gas (LPG). Its efficient, relatively cheap, and widely available. Its also highly explosive-particularly with regards to boat installations-which makes proper installation and regular inspection so critical in onboard systems.

Island Packet Estero Used Boat Review
Florida-based Island Packet targets a relatively narrow niche, so the toughest competitors to its new boats are often older Island Packets. Introduced in 2010, the 36-foot, shoal-draft Estero is the company’s latest attempt to introduce a distinctive model that doesn’t stray too far from the company’s proven formula for success: moderate displacement, full-keel cruisers designed to be lived on, sailed far and in comfort, and endure the bumps, scrapes, and storms that cruising boats inevitably encounter. After sailing the Estero on Florida’s Sarasota Bay and inspecting its interior, construction, and systems, Practical Sailor testers noted that the shoal-water cruiser will appeal strongest to Island Packet fans who’ve been waiting for a shoal-draft, easy-to-sail boat that compares to the IP37 in terms of interior space. These strengths will be most apparent on intracoastal or riverine adventures like the Great Loop.
