Opinion please on a possible boat

Good day,

I am currently heading up a research group where we develop methods and algorithms to detect, classify and track cetaceans using passive acoustic monitoring, i.e., we only record dolphin and whale sounds. We mainly work in False bay, near the Cape of Storms/ Good Hope....

After a lot of deliberation, I settled on using a sail boat rather than a motor boat, mainly due to fuel costs, and also due to engine noise while recording sounds.

Currently, we have a 26 ft Beneteau First. It is an awesome boat, and sails like a dream (in my opinion). However, the Beneteau is a bit small, with 3 people the cockpit starts to get cramped.

I would like to upgrade to a bigger boat. Our main requirements would be:

1. Safe boat - I might be taking students with, so safety is the biggest factor

2. Easy boat to sail short handed, must be able to be sailed with 2 persons.

3. Deploying dipping hydrophones from the boat - a single element connected to a wire that is about 9 - 15 long, which records sounds in the sea. Works better the deeper it is suspended.

4. Deploying temporary moored sensors or floating sensors and collecting them later on

5. Deploying towed arrays and tow them behind the vessel.

6. Do extended trips of 2 - 4 days.

Unfortunately, our budget is limited. What would your thoughts be on the following boat, regarding the points mentioned above:

My concerns:

1. The steel hull do add complications, but we have welders in our workshop for which the labour would be free.

2. The high free board of the ketch is worrying me, especially when we need to retrieve sensors. I wonder if adding a "suger scoup" at the stern would solve that problem.

3. The engine is very small for a 10 Tonne vessel, I believe a 55HP would be better.

Your suggestions, thoughts and opinions will be greatly appreciated
Jaco

Re: Opinion please on a possible boat

I'm biased... however....

That gumtree boat looks a bit on the far side of unsuitable.... the mizzen will be nothing but an ongoing pest.....

There are number of Westerly Oceanlords on the market at any given time... they- like everything else boat wise - are slow to sell just now... https://www.yachtworld.co.uk/boats/1...nlord-3532591/
OK they are in Europe or the Carib... sounds like a good excuse to go sailing to me.

Nice wide stern and a good quarterdeck for your purposes

Re: Opinion please on a possible boat

Have to agree with El P about the steel ketch. The mizzen and its rigging will take up space in the cockpit and aft so that it will seem smaller than the Beneteau. Everything being steel, it will all be HEAVY and slow, and continuously rusting. Ugly, too, and a mess below decks. Not a lot of sailboats on Gumtree. There is a Van de Stadt which might be suitable: https://www.gumtree.co.za/a-yachts-s...00910260054709 . It is bigger than your Beneteau and the cockpit seems big enough. Van de Stadts generally sail well, though this one’s hard chines might impact that somewhat. The price is right, but not much information in the ad about the condition, construction, or other details. Those factors could be why the price is where it is. It would probably be a good idea to keep looking.
