Prop Drag :folder vs Max

The Max-prop has a touch more drag than the Martec but the difference is small, especially as compared to a fixed prop. I don''t agree the Max-prop is far more efficient in normal motoring. ...

Mooring off Stern?

He almost assuredly has a fat roller furling headsail, which adds a lot of windage at the worse place. We sail with hanks and move around at anchor a lot less because of it. We have occasionally...

ESPAR heat

We have dual heated air supplies using a common duct system. One is the conventional Espar air heater. The other is a Volvo QL heat exchanger that uses the closed 50/50 glycol loop on the engine to...

solid fuel heaters

The recommendations on the espar site are crude at best. They give a length range but don''t even discriminate bewteen sail and power. We have a 41'' finnish built sailboat of moderate beam and...

solid fuel heaters

We don''t directly put heat into the bilge but have not seen a condensation problem. We have a waterstop in our keel stepped mast and the bilges are dusty. Which is a good thing as our shallow...

solid fuel heaters

We live and sail in Alaska where some might say it never gets warm. Not ever:) Over the years we''ve had a variety of heaters. The latest generation Espars are great. They are far more reliable...

Radome location

Hi:

We are happy with the Raymarine radar and have found the MARPA easy to use. I was looking at the BT Global Challenge website and noticed they have their radars on a fixed mount at the stern,...

Radome location

Wayne, your points are well taken. I had read the Raymarine website (we have a Raymarine setup), but also talked to a number of people with fixed mounts who had found in practice no ill effect, and...

Radome location

We went through the same question last year for our new 41''. Settled on a stern pole, no leveling and are happy with the choice. Reasoning included most radar use is under 12 miles, we find often...

Self-Tending Jib

Self-tacking jibs are very common in Scandinavia, using a curved track and a traveler car. You don''t need a club foot, which are known as leg-breakers for good reason. If you go to the Rutgerson...

Fractional Rigs - Beneteau, Hunter or Other ??

The Farr 1020 is a good boat - we won the Straits of Georgia overall in the mid-80''s on one. The problem for the Pacific NW is they are sticky in light air. It happened to blow for Straits the...

engine facing aft with saildrive installation

Both Volvo and Yanmar make reverse saildrives. There is nothing inherently wrong with reversing the leg so it faces aft when installed ahead of the engine. That said, all the usual issues of engine...

Cedar for Marine Use

You''re on the right track with Afromosia. The problem with red cedar for seating is the low density. Although strong for its weight, red cedar is relatively soft. Even a rivet in a pair of jeans...

Chartplotter

Assume you mean a below deck autopilot when you say "pilot", and when you say integrate with a chartplotter that would be to input courses on the chartplotter that the autopilot could follow. We...

Produstion custom boats

You know the problem, the production yards save money by standardizing as much as possible and strongly resist changes. Smaller yards will make changes but you don''t get the production efficiencies...

WESTSAIL 32 and similar

The original question comes from someone new to sailing, who wants a boat to learn on and coastal cruise, and ultimately if things work out go off-shore. I would hope even passionate defenders of...

Small outboards

The first decision is 2 stroke v. 4 stroke. As usual each has pro''s and con''s. Biggest pro''s for 2 stroke are simplicity, lighter weight (5 hp Mercury 2 stroke is 45# v 55# for a 4 stroke) and...

Zodiac/Avon 285/310 required engine sizes

We also have a Zodiak 310 with the HP floor. On the other end of the horsepower spectrum, we ran a 3 hp Johnson on it. It would plane out easily with one person if you moved forward (steer by...

ST6001 vs. ST4000 auto pilot

What will you be doing with it? Motoring in flat water the 4000 will be fine, and save $$. If you get into open water the 6001 (with appropriate ram etc.) is more the answer. We have the 6001 on...

Stern anchor suggestions

As mentioned, it is all about intended use and type of bottom. One caution about the Fortress. We have found they need extra care in setting. As an emergency hook (the first use listed), they may...

Steel vs Fiberglass

It comes back to the same theme - what do you expect to be doing with the boat? If you expect to be sailing full tilt into uncharted rock filled waters, by all means buy a steel boat with a 2.5"...

There was no mention of the boat being left in the water over a winter. Given that, Jeff''s point of it being a risk is correct. However, I have left a boat in the water with below the waterline...

J-40 for Long Distance Cruising ?

Jeff''s analysis is right on. Compare published LPS numbers with those for the same boat with an IMS certificate and you''ll see the IMS numbers are much lower. A key reason is IMS assumes a flat...

Hall vs. Selden Boom Vang?

We got the new Hall QuickVang with the air spring. It is light and works well. The first one wouldn''t hold air but Hall replaced it, including picking up the shipping expense. Best thing about it...
