Do Cat Owners Actually Beach Their Cats ?

Maybe that was what happend with that FP.
Still, looking at the keels on the FP:s I have seen, they look quite short and with sharp corners, which doesn't feel strong enough.

No problem Tolly. What happens is your friend was first hand, you are second, and we are third - which is a long way from first - ya know what I mean?

Having received this info straight from FP I can say this - I'll still avoid putting all the weight on the keels. What it may not take into account is the weight of the generators, extra diesel tanks, etc. I would conservativily estimate that Palarran weighs 8 to 10k lbs more then it did at the factory. If the blocking isn't perfect that would be a lot of point load. And if there is a rock 2" below the sand that it's beached on? Could be trouble.

Regardsless of this I leave this discussion now and let you continue with it, happy that I don't really have to worry about the issue.

I am now in the process of moving my boat home to Melbourne,
Where I will be repairing my hulls,

But these hulls will be stiffened and supported through out the full hull lenght and I will be able to set it on any sandy beach any where I choose to park it, with out damage,

I am also looking at installing a V under the bridge deck to reduce slam from the small Gap there is under there.

A few other minor changes that I will do, This is going to be one hell off a boat when I am finished with it,

I do like indestructible, Hahahahahahaha

Cheers,
Brian,

The later explanation was that the FP:s are not strong enough built to stand on their keels without extra support.

If FP paid for the fix, says to me that not meant to do that - and if other owners have not regularly been breaking keels / punching through then FP probably right. Maybe that boat was built on a Friday? (or had a hard landing(s) from the hoist?).

Nothing is indestructible and if your not careful you may find this out the hard way- again!

One thing you might think about in your quest to make the boat indestructible- you may make her so heavy as to offset the balance and she could ride lower and slower in the water-and not be very good sailer - try using Kevlar its a lot lighter and a lot stronger- I did my bows under the water line with this

I’ve also was at the FP factory where I picked my boat up - all were standing on the keels only- I’ve beached mine with no props and also at haul out time i have not used props and have walked all around the bows this way- I’m lightly loaded at the bows-

Like so many stories that are second hand the "story " Tollys friend told him sounds like the old fisherman’s tale of -Fish are the only animals on the planet that continue to grow after their dead. Each week after the fish was caught and eat the fisherman retold the story and it gained 10 pounds each time the story was retold- 20 pounds each time others retold it!

Any thing man made has built in obsolecence, and will self destruct in time,
Its a 34 foot Cat, Not a battle ship,

I understand and that time could be ...anytime!

Whilst I have never been one for taking what folks say as gospel, many things do go into the pot - at least for future consideration.

In this case, if spending $250 or $500k I would consider it prudent to at least consider how sensible an action was before doing it. FWIW I do have a long history of simply giving things a punt - and events not always going as intended / hoped for ......so not averse to the principal.

How much thought is, as always, a matter of personal choice .

Ram is probably right, every kg that you add while trying to beef up any boat needs to be offset by a reduction of weight somewhere else or you will end up with less clearance than you already have. Probably better to accept the Gemini as it is,it does a lot of things very well and some things better than most cats like fit in a marina berth and haul out with any travelift. One thing that hasnt been mentioned is that structurally daggerboard and centerboard multis have tremendous strength imparted by their trunks which is right in the area where they sit on the bottom, the only problem is that not having that mini keel is it it harder to work on the bottom when on the beach as well as of course the sharp rock problem. I was on a Gemini recently that had had previous repairs done a few feet ahead of the trunk which was probably from a point load.

I'd like to see the pics. To post click on the Post Reply tab at the botton of this page and then it will open up the Reply to Thread window. On the top of that window is a paper clip which will open a window which will allow you to browse through pics on your computer. Click on the ones you want then click upload and there you are.

Recently out cruising we met up with an old friend from our yacht club. He has an FP Venezia. He told us he has successfully beached his cat several times for maintenance...........from the horse's mouth to me

What about fitting a "shoe" to the bottom of the keel? The keels are timber and epoxy coated, and I am thinking of taking them to a metalworker to have 316SS shoes made up now in 5mm plate, before the keel is fitted.

Would be real shame to throw away all your hard work, even if that was a long term thing (and likely the problem of a next owner). My answer would be to add something to the bottom of the keels, the question would only be what.

I certainly think that now (whilst still building) is the best time to address this, if you decide to.

If not simply layers of (sacrificial) fibreglass I would personally also look for something that could later be removed and replaced (without chopping the keel(s) off!) - even if unlikely that it was you who would be doing that......but you never know!

In addition to the methods previously mentioned, have also seen folk using simple wood (hardwood) on keels as sacrifical strips albeit that mostly on smaller vessels (might be done on larger boats, just have never seen it).

One thing to bear in mind is if fixing via screws (or bolts) from underneath that can be source of water ingress, plus the heads are first thing to wear off!....have seen a few boats over the years where the keel bands dropped off!


Yesterday I took a few snaps of a Catamaran that was parked a couple of boats along. Appreciate that a Catfisher is not exactly a performance boat!, but this is what has been done (no idea how old the keel bands are, but she has been a drying mooring as long as I can remember).



The bar has been fixed on using simple welded on tangs (look closely and you can see the bumps) - possibly thru bolted (the usual MO) - and then glassed over.



A couple of of other Multihulls in the harbour (including a small(?!) Lagoon) - but they live in the muddy bit, so I won't be wading through the mud just to snap some pics! But I do that on occassion, so might snap some pics - if I remember .

Would it be worth the effort and the $1000?

IMO, if beaching is intended on a regular basis (rather than occassionally to antifoul etc, in carefully chosen places) then I would. But I ain't claiming to be an "expert".

Of course nothing lasts forever - but I would prefer to replace a keel band than an inch or more of keel, on any sort of boat:-



This on a Wood Mono (keel is solid hardwood, dating from late 60's) - fitted around 20 years ago (by my Father - boat long since sold, to a succession of idjuts ), that would have been at least 1/4 inch steel bar. Obviously rust would have played a part in it's present condition - but more about having been beached twice a day (drying moorings over here).

[clockwork orange]

Years ago we used to screw a sacraficial piece of Totara, (a worm resistant New Zealand wood) to the bottom of the keel on powerboats we built for this very reason, these were production fiberglass 40ft planing hulls

My boat is a mono hull but is made to be beached. Really made for the tides in England has retractable keel so it will sit straight up. I have beached it a couple times its fun watching the other crews as we go aground. Check out the Southerly's.
