Well, so many comments here it's a job to know where to start:
Stiff Suspension - a mono rolls (not always right over) and a cat is like a jeep going cross country unless the bows and hulls are very slim which makes them more likely to pitchpole when pressed. Bro and I used to go stand on a bow each on sailing demo's. Only one boat had us scuttling back to the cockpit
pretty sharpish and that was in sheltered waters on a french boat with vertical stems and finely tapered bows.
In short seas and an f6 my 30fter was hard to get around on, handhold to handhold being the general technique. On a cruise
you find a kindly heading then look for a destination
in that direction. Where were you headed for anyway?
Comments on weight and squeeking are quite right. I'd suggest strengthening the structural bulkheads where the history
is uncertain, paying attention to the known weak points on the Catana
. The solution to squeeking is easy for you, just don't build furniture from floor to ceiling because cats flex when they are supported on two opposite corners. Secure furniture to the wall OR the floor.
You do gets lots of deck
space that can be vented below so storage
for gas, fuel
, wet sail, dirty anchors and so on is easy to install. Just make sure the hatches are solidly fitted and hinge the right way not to be opened by green water
over the bow.
I don't know what the rear deck
space is like but I'd look to add a forward facing watch seat at the very back end of each hull
. It's a lovely spot to stay awake and enjoy good weather
. A shallow backed bar seat at the helm
is better for wetter days but pleeaase don't fit a windscreen. They're useless in the rain and add drag to a fairly streamlined top shape. makes it difficult to link up with anyone working forward too.
doors must slam shut if you're swamped from astern. NOT sliding doors in plastic that will allow the saloon
to fill with water
Personally I'd have a serving hatch
so the watch can be served hot drinks without the indoor folks getting cold draughts.
Apart from that you just add such cradles and stuff for diving gear
as you need. A good diving
ladder and an easy place to keep, launch and recover your dinghy
all make life easier.
(the flexy sort that charge in cloudy weather) will run all your usual boat stuff. Add a petrol genny if you want air conditioning
with the petrol stored up forrard away from the dinghy
I found clip on points for the dinghy really useful when transferring gear/people to the boat. And take the chance to hoik the mast
and rewire everything now. I'd use some bendy plastic water pipe to run all the mast cables
in to prevent wear and tear.
You've enough experience to make a really good job of a boat you can fit out to your needs. Just don't waste the space. My bro served 12 guests Xmas lunch in his Snowgoose. Generally only the mid or read is fit for sleeping at sea but the forward area of the saloon makes a lovely big proper bed
for marina stays if it's curtained off nicely.
I much prefer the galley
in a hull
. Spills are easier to manage, rough weather
is easier to cope with while preparing and cooking
, and all the washing
up can be left 'till later without making a mess of the lounge.
A framed bimini
with soft top and curtain sides is the best bet, good access to the boom and main with easy to change wind
and weather protection when you need it.
Make sure you have can rig a storm staysail to keep steerage way so you can ride the worst out without leaving the cockpit.
How I wish I had the chance to build from scratch!!!!! Too many ideas for one boat. But it would be a cat!
