Looking for a Low-Cost Easy to build multihull sailing design

[kekdu]

Hello everyone, as the title suggests im looking for a Low-Cost Easy to build multihull for me and my wife. We are not experienced in building boats. I think around 25 feet multihull will offer us a comfortable space. I'm looking forward to hearing your suggestions and ideas.

Richard Woods Eagle 24 fits all your requirements.
Plenty of information and pics online. Check out the Woods Design website for details. I also recommend reading the articles on his site, there is a wealth of good information and advice there. Also a forum where Eagle builders connect and post pics.

A good boat from a good designer.

Kekdu. What are your skills, can you work with wood, plywood or are you skilled with fiberglass? Do you want to keep the boat on a mooring or trail it home? Do you want a full standing headroom cabin with a galley double berth and toilet? Is it for sailing in a bay or coastal cruising for a week. Do you want to sail fast or cruise along? The answers to these questions will guide people to a better answer for you. Hope this helps.

i have minimal experience with plywood and no expereince with fiberglass but the building will take place on a friends farm so we will have additional manpower and handy people who can join us and another friend who works on huge wind turbines which uses very similar material to modern yachts. I will keep on a mooring. Full standing is hard for me since im 1.94m. I want it for cruising so yes we need toilet/berth. THanks for the help.

Eagle 24 looks like a solid choice. Thanks.

Check catamarans by Bernd Kohler, very simple but clever designs.

Sango ( hard chined version) is a great choice I would chose over Eagle myself…Both by Richard Woods

 

[Burger]

Sango and Eagle are very different boats, despite being nearly the same length.

Sango (hard chine) uses 123 sheets of ply. Eagle uses 42 sheets.
Sango weighs 0.9 ton, displacement 1.4 ton. Eagle weighs 0.65 ton, displacement 1.25 ton, so 100kg more payload.
Sango would take considerably longer to build, due to the folding beams and cuddy cabin. On the plus side, comfortable enclosed deck cabin, and easy trailering. (Don't forget to budget for a large trailer and suitable towing vehicle.)

Eagle is simpler, cheaper, quicker to build. Sango would be more comfortable for a family. Performance/seakeeping would be about the same, excellent as Woods boats are.

If you are not experienced in building boats, it will take you several years to finish the project. Ask yourself if the main goal is to learn boatbuilding or go sailing. If going sailing is the goal, a used boat is cheaper and faster.

Eagle does look like a good choice ,if you look on the Woods builders forum,Peet extended his to 25.5’ approx.
…Peet has some good ideas and photos.
I have Eagle plans , Sango’s Cuddy appeals to me and as mentioned above you can add a Cuddy in a few years , if TR is Trinidad….
Eagle is a good choice ….

Epoxy glue is recommended for all glue joints as it is gap filling and the strongest and most watertight glue

Sorry Redreuben,
but (imho) I do not consider a Scarab to be an easy build. There are way too much planks to cut, fit, glue and sand fair to be simple and fast. For an unexperienced builder too much manhours to build and too much opportunities to make mistakes and up with an unfair boat.
Have Fun, Michel

That may be, but your not the OP, so…..
I’m just providing options, in my observations here builders like $150 plans V $1000 plans, it buys a lot of epoxy.
But that is not my call.
