Question
Catamaran Sailboats

Hello. I wrote that I was a novice on the water. I wanted to build a boat RG65 JIF. I can not do only "bulbkeel". So I thought to circumvent this problem, build a catamaran. Traditionally, balsa and plywood. I can not find the plans. Many links on the internet but old and not active. Something on this shape.

Hi:

If you are a novice sailor, I would suggest to do a keelboat first. Catamarans are very tricky to handle, the biggest problem being they tip-off, and you will find yourself 90% of the time walking/rowing/swimming to recover it!

What are your restrictions on keelboats? Pond depth? There are keelboats for almost every pond!

Hello
on ebay, under "toys and hobbies" search "rc sailboats"
you will find pre-made keels from many production sailboats sold as parts.
can you use a pre-made keel for you boat ? they have many parts for RG65
type boats there also.

It is too expensive. Maybe in the US it is cheap but for me too expensive. I build my models - not buy. In the opposite event, i bay a catamaran on eBay. Ready with transmitter. I ask again do you have a plans for catamaran ?

Where are you from? I'm sure lots of people can help you here on getting a nice keel+bulb for little money!

Most of us build our own stuff here... But again, some parts its better to get already made instead of making them yourself. Lead is a good example!

If you go for a catamaran, do not say we did not warn you about their difficult handling! Here you have two pointers to some modern wing-sail cats:

I know the two links that you sent and I know 100% that do not contain plans. but they contain information content such as: "$300.00 us plus shipping." Someone can answer the question in the subject?

Burakko -

What "kind" of plans do you seek? Some plans are step-by-step with many photos, many pages and you follow each step in the building process. Other plans - like most multihull plans, are just the line drawings - side view, top view and front view. These require you to break the plans apart yourself - and are designed for those who have had building experience - with boats or airplanes. These are the most basic, and do not guide you in "HOW" to build - only that this is what they look like.

Do you have model building experience - or will this be your first one? Please download these construction tips. They are for a 1 meter long boat, and a monohull with lead, but many steps are able to be used regardless of what size you are building.
http://www.theamya.org/boats/us1m/us1mcons.php

If you must build a multihull, I suggest a trimaran, and you don't go smaller than 1 meter in length. You will be able to see it on the water, and it will have room for your electronics inside. The trimaran, as opposed to a catamaran, will be a bit easier to sail, and while they can tip over, they aren't as quick to go over as a catamaran.

Finally, can you tell us where you live, please. It helps for those giving advice - as to sources for lead, electronics, sail material, etc.

After you look over the documents at the link provided, and if you still desire to build a multihull boat, post back here. There are a few of us who probably can help with plans once you are positive which direction you want to go.

- Final question - can you have DXF or DWG format building drawings converted or printed to large paper where you live?

Best regards, Dick L.

So that:

Dear tarmstro thank you very much for your message.

Sir Dick L. - What to build the boat I am a beginner but I built several aircraft, gliders and hovercraft. The boats have a proven hull IOM class of fiberglass. But I will not have access to the lathe did not perform Keelbulb.
As for the plans that I know what you mean. No difference whether it's 3 throws drawing or printouts elements
Sorry for the english but I'm learning. I understand what you write but I lack the words to comment - sometimes. Thanks for help me...

Give those above a try.

I'm sure German, French or U.K. monohull sailors could send you information on purchasing a lead bulb for your boat if you wanted to finish that one.

Now I'm going on vacation. I take a lot of balsa. execute frame and floats. At the beginning powered propeller them because I did not have time to make a sail. I will be praised during construction. Thank you guys for your help.

I have lots of place to sail https://www.google.pl/maps/@52.4877264,18.6388876,15z
