Who likes the idea of those bare legs and other parts meeting a spinning prop during an upset? If you really have to go electric why not couple...
How about aircraft fabric. Glues on easily and shrinks smooth with an iron. Paint it with the pink primer and it is airtight, use the silver...
One of the problems today is that everybody wants what THEY want. By its nature a good school boat is not high performance. A fast boat, light...
Perhaps the best way to appreciate the dynamics of sailing boats is to sail dinghies. I sailed them for ten years, all sorts. I never got the...
Two things, Weight at the longtitunal ends of the boat will decrease pitching compared to weight added at the centre. Longer moments mean it...
Looking at some of them there is not enough depth in the aft hull for accommodation. There are several reasons for carrying the beam all the way...
Hulls are designed so that contact is progressive and obviously most of the weight is supported by the wings at contact. The problem also happens...
Hi Will, Probably not an engineer's bag, more for a hydrodynamicist. Glassy water has qualities all of its own. It's a well known phenomenon...
Small point. Flat calm water (glassy) creates more drag than small waves. (Landing a flying boat on glassy water is dangerous because, amongst...
About the crew. Astonishing to think the design crew for Cutty Sark was 26 including Master, Mate, Carpenter and cook! One trip from the far...
Actually there is a very good engineering reason for 'catwalk' side decks. If you look at a f/glass hull newly uprighted before the deck is...
At some stage the designers decided that long narrow bows that drove easily were less drag than traditional broader bows. (And for those pesky...
"The trend to open interior spaces and huge cockpits are great for people that spend their time at the marina though." That Cat I mentioned with...
Incidentally, the OP did not specify cargo carrying, he mentioned it in a later post as he was "interested" in traditional, possibly "work",...
Your example of a Cape Cod cat boat is essentially a day sailor. I see very recent boats 50 or 60 ft with cockpits just 6 or 7 feet wide. No...
John Smithson. I'm with you. Far too many espousing the line "Look at the way boats have been built the last 200 years, that's the only way to...
In fine weather, as a pirate, you tie your victim to the mast. When it's cold and wet she complains too much and you need the king post below.
Do twenty years in the business. Build a very, very comprehensive list of people who love you, will be your agent, promoter and recommend your...
From what little I know about aircraft wings, tip vortices also occur on broader wing tips. How about semi stiff tips placed perpendicular to...
The top of a main is less efficient in terms of useful energy usually for two reasons. 1. It generally has less control than the lower part of...
