l. Inboard or ANY type is vastly better than an outboard. Reason: the
outboard prop being mounted far behind the tansom may come free of the water and have the rpm go 'exponential' when the prop is not in the water. When pooped by a boarding wave the transom hung outboard will flood with water which will/may 'hydro-lock' then seize and stop. 2. Stern hung rudders will 'ventilate' - sucking air down the sides of the rudder - thus making them VERY inefficient and causing humongous drag. Stern mounted pintel hung rudders are usually an unbalanced design requiring huge loads to move them off center when the boat is a 'at speed'; plus, are very vulnerable to breakage if the boat slips backwards such as when hove-to. The choice for a 'modern' boat: inboard engine with 'under-the-boat' rudder. thuIn article .com, Lee308 wrote: These two choices seem to vary widely in sailboats between 25 and 32 ft.

Sure..... when hove to in extreme conditions I find that its ususlly
better to heave-to more 'on' the main than on a jib ... so that the boat slowly backs down and stays with its turbulence slick (caused by slipping the keel... such turbulence in the water will cause a brteaking wave to actually break long before it gets to the boat. My issue with stern hung rudders is that when running off in heavy seas is that they take a pounding from stern boarding waves. Its all in the 'geometry' of the attachment making the rudder very vulnerble to huge generated forces simply by 'trigonometry'.

I don't recall ever slipping backwards while hove to. General a very slow forward motion. Were you thinking of a situation where you've got large waves at right angles to the wind direction? |
So, whats your point .... and supporting data?
Care to 'articulate' .... if you're able (but I dont think you're capable) Get your meds changed/adjusted, you're clearly in distress.

Red Cloud,
I piloted a 25' Pearson with an outboard. When coming out of the channel into the lake, the waves would start to rock the boat fore and aft, causing the outboard to come out of the water. Yet this was a long shaft sailboat motor, I'd have preferred an inboard. IMHO Paul Red Cloud® wrote: On Thu, 02 Jun 2005 01:46:45 GMT, Rich Hampel wrote: l.

: In 5-6 foot seas. It was no great cause for concern. rusty redcloud That'd be OK in a lake or fair day close to shore. Does it get dunked over the powerhead in a following 12 sea with waves crashing over the stern? The diesel doesn't..... |

Speed of boat is not an issue. Not widely. Most boats 27' and up have inboards. 1) Diesel inboard or over the stern gas outboard? Outboard easy to reach and repair/replace, no worry of shaft seal leak and less thru hulls, but small diesel's are very fuel effcient plus large alternator. What's to worry about re/shaft seal? 2) Over the stern rudder or binnacle/shaft type rudder? Once more, seems the over the stern rudder would be less problematical and repairable even at sea. No thru hulls or gears would seem better. Skeg hung rudder-if you're really worried about the rudder, you should be worried about losing the rudder more than anything. You seem overly concerned about sinking. You know they have cruisers that are advertised as unsinkable, may be you should consider one of those. http://www.etapyachts.com/ John Cairns Yout thoughts would be appreciated.

Thanks. The children are much older now and enjoy sailing very much. Years
later they asked me if some of the situations in which we sailed scared me as much as it did them. (I never intentionally put them in any danger, but sometimes a sudden squall would pop up or there would be an occasional rough sea.) I told them that sure I was scared, but I did not have time to show it; I was too busy thinking about the options and plans B and C should anything go wrong. They are all married now, but we had some great sails together when they were younger. Tom "FMac" wrote in message ... "Tom R." wrote in message ... The water would come over the transom and the engine would start to sputter. "Putt, putt, putt, varoom." The look from the children and spouse would be answered by, "Don't worry, it is just gasping for air." My look of confidence was not shared by my brain which was thinking "this is stupid, get an inboard." I admire your tenacity during a somewhat difficult situation. You have a skill shared by few. Your children will never forgot your look of confidence and will have a grand time sailing. |
