Peace for sure. I guess I mistook your comment that 'the Lagoons, Privilege, Catana, most of the So. African cats I've seen, all seem to have pretty good clearance' meant all of the Lagoons, Privilege, Catanas and most of the S.African cats. In any case, I'm assuming Twisty will begin to ask boat specific questions as she starts inspecting some boats - and I suspect that would probably be the best time for all of us to chime in with specifics rather than generalities intended to, or capable of being interpreted as applying to older boats in general, or all models of boats by a given manufacturer.

Yes as I get further into this process I will definitely want to get into certain boats specifics, but at the same time general rules of thumb, so to speak, when beginning isn't a bad idea either so I really appreciate everyones input on this.

As such, sufficient bridge deck clearance has been added to my requirements list. If I am going to be alone sleep is going to be an issue and needs to be as uninterrupted as possible. Never mind the consequences of a boat constantly being pounded because it does has enough bridgedeck clearance.

My sailing for dummies book should arrive tomorrow so I know I will have a million more questions.

P.S. a $400k boat is out of the question, unless I win the lottery in the next few months, and in that case all I will need to know is what is the best boat money can buy and who can I hire to crew it...lol

So much anti-cat sentiment on a website that highlights one on it's main banner?

To each their own, remember that.

ok lets get back to one of my original questions.

Is there anything I should be looking for knowing I will refitting it for solo handling?

Go Sail, you can always motor if you need too. I would recommend not getting a boat with saildrives. Stay with desel, stay in the 32 to 36 range, all those lines can be lead aft for single hand sailing. The PDQ is a great choice, small enough to handle and large enough to go anywhere.

Cheers and Good Luck with everything,


Todd

Major lines led aft.
Jib or Genoa on a roller furler.
Single line reefing.
Simple easy to use autopilot (ST4000 is what I use)
Bimini, preferrably hardtop.
Chartplotter at the helm, not the nav station.
Low steps to the water on both sides.
Twin engines means more likely that at least one will start and better slow speed control.
One engine means cheaper maintenance.
Dinghy davits.


The biggest thing for me was feeling safe and secure. Any boat feels very small out of sight of land, including Destroyers. I was looking at the PDQ and the Gemini. The PDQ is MUCH more solid than the Gemini which was cheaper and probably faster in light winds. I also wanted a boat that was already dinged up, I find myself more relaxed about the kids beating it up that way.

Could you please indicate how this post adds to constructively answering Twisty's questions?

Twisty, I think it needs to be emphasised that bridge deck clearance is not the only factor in causing the slamming.

As has been mentioned, the clearance needs to be considered in relation to the width between the hulls, but again this is not the whole story.

Probably one of the most crucial points is the design of the bridgedeck to hull join. In early cats this was a 90 degree corner. It was quickly discovered that this lead to such slamming on this join that some actually failed. Much experimentation followed which discovered that a good radius to this join allowed the water force travelling upwards at the hull edge to be redirected horizontally. This protected the join, but also reduced the slamming significantly. You will see on some cats, especially those with the lower clearance, that this radius has been taken to extreme in an effort to reduce the slamming. Thus most of the worst slamming now is purely the wave crest catching the centre of the bridgedeck, rather than the much more dangerous wave at the hull edge.

Excellent info, I am taking notes!

And the rail seen running along the bottom of the bridgedeck is made to reduce this beating even further?

Not all cats have these rails - they tend to be more for ply construction or earlier GRP (Catalacs have them)

They are much more for strengthening the bridgedeck against the slamming than for reducing slamming. Most of these are far too small to do anything worthwhile about the slamming, and are the wrong shape/position.

Some cats do have a large nacelle under the bridgedeck specifically for the slamming. This is taken to the extreme with the Prout Snowgoose. However, if these nacelles are underwater, they significantly increase drag - this happens with an overloaded snowgoose. The Prout Escale had much more clearance with the nacelle, and was much faster.

Privilege have a form of central nacelle at a much higher level than the bridgedeck, which does help to reduce the slamming.

Did you mention what your budget is ?? So you dont keep getting a lot of information that would not apply to you? I see so much info being put out here, but I have not heard what would be realistic for you?
