Semi-Displacement vs Planing Hulls

[Guest]

I have a 25ft sports criuser (planing hull) and am thinking of changing it for a Beneteau Antares 7.60 or 9m which are both semi-displacement and capable of 25 knots. Are there any advantages or disadvantages between the two different hull types?. Also does anyone have any experience of these two Beneteaus.

I would appreciate any information anyone can offer.

Regards, Tallon

Much depends on what you want to use the boat for. If you are doing alot of fishing and river use. Probably go for the semi displacement. I would think them more comfortabl when stopped and better handling at river speeds. On the other hand, a planing boatwould be much faster.

Hi

I have no knowledge of the boats you are looking at but would say that usage is an important factor.

Planning hulls are faster and like for like use less fuel - due to the obviously less drag of not having to push the full displacement through the water.

If it were me, and I was looking for something to 'play around' in and cruise modestly then my opinion would be planning.

If your looking for serious cruising id go for semi or displacement these being my reasons....

For a planning boats hull to be working correctly/ efficiently it has to planing once off plane the hull isnt working as it was designed to do, so if your caught out in bad weather, so bad that to get to planing speed is uncomfortable or unstable or unsafe you are left in a semi discplacment movement with a planing hull- the hull then not working as it should.

If you have a semi displacment or displacement hull all time the hull is working as it was designed to do irrespective to a large part on speed, with no need to get onto plane for the hull to be efficient.

Therefore If i was cruising a lot, France , Channel islands etc and wanted to be less restricted by weather and sea conditions Id always go discplacement not forgetting the extra fuel costs involved!

again I do not know the specific boats you mention. hope it may help

We took delivert of a Series 9 in February and have been particularly pleased with it.
Cruising speed approx 15 knots (Volvo KAMD43P) 18 litres approx per hour.
Good handling at all speeds although we reduce speed when necessary for a 'more comfortable ride'.
Able to take the ground (with legs).

If you would like further specific info etc. please PM me.
